first, check fuses, next, check remove clean all terminal ends, 3 rd, chuck wobly.. back in 1973, i learnt, cables, earths, corrode. so now i paint, grease, oil, protect them..posative earth cars were better.. 1800,s.
I first checked if I was getting power to the starter (obvious if you are hearing clicking though), then I might use jumper cables from the battery to the starter and see if it functions. This is more diy though, but a quick test of the starter. If it works, you know to look else where. You know the signal wire is good with the clicking, so really its battery, battery connection, or wiring.
65? You're just a damn kid!😂 I'm coming up behind you, fast! I'm turning 40 in December and I'm still learning and trying to retain a lot if information. My father who just turned 65 once told me about working with drywall compound that if you can't get it right, the hell with it. Get out of it. Let it dry. Cone back tomorrow and sand it, and hit it again. I remembered that as I was doing some drywall in my own house. There is a lesson in that for all of us in all aspects though. It's that in our obsession to get it done or to make it look the best today or succeed TODAY, sometimes it is best to just say "the hell with it" and take a step back, or just take a break until tomorrow when we are rested and/or refreshed and ready to give it another shot. Sometimes doing nothing is the best course of action. Might seem counter intuitive. But if you're making mistakes and getting frustrated today, you're work is going to suffer until you are ready to focus and do your best again.
I changed a starter on a 78 Pont Catalina in the snow, because I thought it was bad. didn't fix it. Towed to a local shop, he called before I got home, it was the ground cable. charged me $15, I was very happy with his work.
The sad part is that there are any number of shops out there who'd throw a starter on it, discover the corroded cable, and then charge the customer for both 'repairs'. Customer would get a substandard starter and shade tree cables... At a premium price of course!. It's always a kick to watch a real technician at work!
You are one the very few honest-to-a-fault mechanics out there who will take responsibility for a misdiagnosis and wear the cost of a new starter. (although that's very rare at SMA) We all know that often, especially dealerships, just shoot the parts canon at a car and charge through the nose for each part. (and that car often ends up at Eric's place)
work for the AA in the Uk, its amazing how many breakdowns I go to that have just had starters or alternators fitted, when all it was is a poor cable. what's also amazing is the amount of qualified people fixing this stuff that don't know how to do a voltage drop.
I love the way you showed how to do active drop testing even when you don't want to turn the key when intake is off. The common excuse by pros is that it is too much trouble to do drop testing when you can't get at the terminals without major surgery. Once they do that, they feel committed. Time and again you show how drop testing doesn't need to be a time waster, you do it quickly and efficiently. The trick is to select a few quick, reliable screening tests and move on with your day if those tests check out.
Eric....as a lifetime electronics troubleshooter, I often smile at some of your explanations. Certainly not the way I would explain it, but you are demonstrating techniques to people watching you troubleshoot. Your explanations are excellent. When I have been called upon to teach people techniques, I am talking to folks who have an in depth understanding of the circuitry involved. My explanations would only serve to confuse your followers. I have watched your videos since day one, & I am always intrigued by your explanations , that are just as if we were all standing beside you. My God ! You provide intensive learning for your followers, without sounding like a college professor, or like some of the nitwits that I have come across that have NO idea what they are talking about. Ivan & Scanner Danner are also good, but Scanner Danner speaks too rapidly , & occasionally misses a link in the diagnosis. I mean that he omits a link in the diagnosis chain that is of no consequence to people who have electrical knowledge, but may be confusing to those who are just starting to learn. This is an observation , NOT a criticism ! Further, it is not a regular event in his explanations. Eric, technical schools need people like yourself & your colleagues to bring their students to your & your colleagues level of expertise. Carry on Sir.... first class trouble shooting techniques await your followers. Cheers! from the wind swept Prairies of Alberta Canada.
I need a mechanic like Eric or Rainman Ray in Calgary. I know a dangerous amount for an amateur, but nothing beats years of experience. If nothing else, I know I won't be taking any short cuts on this 2000 Jeep Grand Cherokee 4.7 rebuild when it comes to the aftermarket electrical upgrades for the storm chasing gear!
Anyone on here that says they would have checked that before is full of crap!! They would have checked it after they put a new starter in, when that didn't work 😂
@@tomtke7351good luck finding that. 99% of repair shops, including dealer shops, just swap the parts the code says is bad. Minimal diagnosis or testing done. Starter clicks? Battery charged? If yes must be the starter. Didn't fix it oh well, the customer still, pays for it. What next? Battery? Ground cable? You'll be $1000 in before they check the positive cable.
Between Eric O. and @RainmanRaysRepairs, I've learned the value of checking power and grounds thoroughly! Very grateful to both for sharing their work and knowledge online!
There was one time I was helping out a fellow traveler on the road because their car would not start. I swapped out the battery (either one I had in the trunk, or the one in my car - for definitive diagnosis purposes) & cleaned (battery wire brush) the battery terminals & cables and the car started. I popped their battery back into their car & it started right up. All that was to say that the corrosion between the battery posts & cables caused enough resistance to prevent the car from starting. Ever since then I am always suspicious of battery to starter connections as a source of high resistance. Nowadays I carry a meter in the car!
So, I guess it's story time. This one involves a girlfriend, a 73 Camaro and corroded side post battery cables. No crank, no nothing as I remember. Unscrewed the battery cables from the battery and lots of corrosion found. Cleaned up the cables as best I could without a brush and reconnected the cables to the battery. There had been zero indication that I had corroded battery terminals. That no crank was the very first indication of trouble. The girlfriend made it home!
@@thomasshaffer8547 Yeah, back in the day you would use a knife or screwdriver to shine up the cables & terminals where they contacted each other, just scrape until the metal was shiny again.
As someone who has worked on Hondas for 30 years first thing i seen was that junky ass battery terminal. Hondas dont like those. Ive got bitten by those before. Just today actually with one with a turn over no start. Spent an hour on it before realizing it had that same junky ass ternimal. Gotta remember to start with the simple stuff first. Even i forget. Great video!
My brother in law recently had nothing when he turned the key on a 2008 F150 5.4. He told me that the starter was a few months old and the battery was good. I told him not to assume either was good. I also told him to test before buying because it is stupid to put out $300 for a starter when it doesn’t fix the issue. He put a new starter on and it still did the same. I told him he could have a bad negative cable. He said it “looked good”. (You can imagine what I said). I talked him through a voltmeter and test light test and indeed it was the negative cable. He ordered a new one and his 18 year old son installed it. Fired right up after cable install.
People who don't know about how cars work don't know exactly what to look for when something goes wrong. They should take a class in automotive technology, or read a book (or two) about how cars work, in addition to watching South Main Auto.
Picture worth a thousand words, or in this case, a video. You've coached us on the value of doing voltage drop tests and this is indisputable evidence of why it's important. Thanks for bringing us along. Part 2?
This was very interesting and informative. I never would have thought of checking for voltage drop first! I've replaced many starters and was lucky to fall within that 95% chance odds. Thanks for sharing this, Eric!
I'm not a particularly skilled mechanic, but I had a situation like this.... and if you are in the dark, the corroded spot will light right up so you can see it.
Fun fact: On those K24 hondoo motors, you can actually pull the starter mounting bolts and drop the starter down from underneath the motor. Then remove the solenoid wires. Saves a ton of time by not having to remove the intake plenum. It’s less of a PITA, in my experience. Great diagnostic video!
I have a 2003 Element with the same engine. Had a bad original starter after 10 years and 150K… shop replaced the starter with an aftermarket… which was bad out of the box. The shop did NOT pull the intake when they needed to replace the starter again the next day… doing that they destroyed the wiring harness to the knock sensor which is also right there. Didn’t tell me about that damage. A few years later when I needed yet another starter as the aftermarket one was dead my new non dealer Honda mechanic needed to call in a few favors to get a full harness to splice in the correct wires and connectors into the knock sensor. With time and corrosion it was throwing codes… fixed now with a Honda OEM starter. 211,000 miles on my 21 year old Element. Still love it. Best car I have ever owned.
We do put a ton of starters on Hondas and Toyotas but those braided ground straps on Hondas also do fall apart in our rusty areas anyway besides all the regular stuff like what happened in todays video but also don’t know why people do such poor wire and cable repairs as they cause so many problems down the road and sometimes not far down the road
I find that on toyotas, the usual starter problem is the "L" shaped contacts in the solenoid. I made some from some copper parts in about 1990, and told my friend at the dealer, who thought that was funny cause toyota sells them separately, and cheap. Now, they are even cheaper on Amazon. It's like $7 to fix them, and very easy. Honda starters, however, seem to go through brushes.
Exactly. I've had people look at me strange when I take an hour just replacing terminal ends with copper lugs and marine terminals instead of the cheap garbage that would actually get me back on the road in 10 minutes. If you're going to do it do it right and don't have to do it again. Between the heat shrink, crimping copper terminal, and then filling the remainder of it with solder I've never had one fail.
That starter in that location with that symptom.... THAT would of caught a lot of folks... including me... and I troubleshoot multiple cars a day, taking pride in being spot on! Thanks for keeping us sharp Eric!
After about 3+ years of learning this from channels such as soutmain Auto scanner Dan western truck & tractor repair. Knowledge is power thanks to channels like this. Much appreciated
That era hondooo is the only manufacturer that still made a starter with very easily replaceable brushes for $13. Typical telltale sign that brushes are going bad is excessive current draw when starting. It makes it seem as if the battery is weaknor going bad because if you put a jump pack on it will seem to crank normal because you've basically doubled the cranking amps available to the starter.
Not sure if this counts on new cars, but we had a car that would turn over but not start till you let off the key. I say we, I was helping my Dad many moons ago. Anyways, best we could figure was the starter was drawin so much juice, it had none left to give a strong spark and why it would fire off just as you let off the key. Upshot was a rebuilt starter and worked good, point being, we didn't know squat about how to test for that and only figured it out by using our ears and grey matter and deduction on an old car with very few gizmo's. These new cars, boy... Glad we have Eric to show us the ropes. Thanks for the great vid!
Easy peeze, try drivability in a new car and you will get into inputs and outputs. Many mechanics will just throw parts at a car because of the variables.
I am 100% sure I would have replaced the starter. And then maybe I would have figured out the wires were bad after I got lucky and smelled the smoke that I probably would not have found. Awesome video…again. Luv me sum SMA video
Voltage drop can trick anyone when its hidden or even in plain view. So many times a headlamp was dim for no reason and the connection looked normal,,, yet she was sizzling with heat from high resistance. A simple removal and cleaning or fix of the bad terminal and it was good again. Good test there Eric using the meter for a confirmed voltage drop.
As always, much respect to Eric for taking the time and finding the issue. As for me, I would still recommend a new starter to the customer since they are very prone to failure and since I had the intake off anyway.
For everyone crapping on mechanics who have mistakenly replaced starters in the past, MOST of the time, it is an intermittent fault. It’s easy enough to diagnose properly when then starter has failed completely, but try it when it only fails once every 3rd Sunday when the old lady is trying to go to church.
I know that the standards for my repairs are different that a paid mechanic. A paid mechanic has to fix the failing part every time, or at least most of the time. Come-backs are costly for the customer and the shop, even if it only to the shop's reputation. Replacing serviceable but worn parts both makes the shop money and avoids unrelated/coincidental failures. For failure-averse customers it's arguably money well spent.
I love to share my experience with a customer telling me he needed a starter. I found voltage drop on the negative cable and replaced the cable from the battery to the block with the negative cable on my 25 foot long jumper cables. I then went inside the car and turned the key to the sound of the engine starting i then checked the cable ends and found the end that was attached to the block had corroded so bad that the plastic cover on the cable was the only thing that supported 2 inches of that cable. I had to remove almost 3 inches of the cover on that negative cable before i found the nice copper color i was looking for. I replaced the $14 cable and bolt instead of the price of that new starter which at that time was about $80 my price. Good video as always Sir!
i would have burn through 2 starters before getting to the battery terminals, not anymore thanks to you MR O, thank you for sharing your knowledge and experience.
Thanks again Eric for teaching all of us DA’s out here how to do something properly. I, like several others people in the comment section, would have changed that starter only to find out I was wrong…. Not that I’m gonna be changing a starter on a Honda or anything for that matter. I still change my own oil and brakes but that’s about it. I’m getting to old to do that stuff……
Great testing Erik. I might have to add that to my starter R&Rs. Voltage drop like that takes seconds with it all apart! Some shops would throw 10 starters at it, THEN send it to you!
Eric has learned- ALWAYS pay heed to that little voice in your head when it starts telling you something! It is your subconscious trying to save you from your EGO! Another great video Eric!
So, in an unrelated, slightly dumb story. Me and my father were going up north from Dutchess County to Buffalo for a family event. My father stopped off for us to take a pit stop and happened to coincidentally pulled over in your town and drove by your shop. I explained I've been watching you on RUclips for more than 5 years I think now. We drove by your shop and I looked and saw and drove down the road you always go down. It was interesting. Would have stopped off but 5pm on Friday and knowing how you feel about non customers just dropping by or calling without work needing to be done. I opted against it. I opened my mobile mechanic business modeled sort of how you do things but with my own twist. Thank you for doing a sometimes thankless job just to keep us educated and entertained.
Good find and demonstration. Plus, you saved the customer lots of money. That's worth the price of admission and why these vids of yours are so important.
This is why I always do a full visual inspection of the problem area before beginning my diagnosis, would have saved so much time here. Never don't untape the harness first.
My mom has a 2007 Accord and it had several problems. The starter went bad, it currently has a bad catalytic converter, both window regulators failed at the same time, a wire broke in the door for the power windows, and another issue was similar to this case. The car wouldn’t crank or start. I went to check the battery and found that the positive terminal was so corroded that the terminal was very thin and didn’t make good contact. I cut the terminal off, luckily the cable wasn’t corroded, and I was able to put on an aftermarket terminal and the car started and ran perfectly ever since. I was able to save money by not having to buy a new cable.
Dorrman makes better than OEM replacment rear power window regulator / motor assemblies. Both went out at about the same time on my wifes 06 Accord. I dont get anything for saying that. I just dont like doing the same repair twice on the same car if I dont have to.
I learnt this exact lesson at the age of 15, it was May 1st 1972, and the very first day of my official employment at the garage of a local haulage company after leaving school. The truck we were to fix was a 4 year old Ford D Series, it presented all the signs of a bad starter motor. However, before we dived in to fit new parts, the old school mechanic I was working under did a voltage drop test. Sure enough we found a full 12 volts where there should have been none. Turned out to be a poor connection on the common earth point on the chassis, this was hidden away right behind the battery. After a through cleaning, and replacing a corroded cable connection the truck fired right up. That "voltage drop lesson" stuck with me throughout my 53 years with the same company, and I myself have taught it to many new apprentice mechanics, and many an old one too. I'm retired now, but the company still owns that same old 1969 Ford D Series, it was the companies very first 'brand new' truck. Many thanks. David in the UK.
Come on Eric...I doubt anyone here would question your troubleshooting techniques!! If you didn't start there, no one would have, thanks for another lesson!
I had the exact same problem after I replaced the connection on my old F-150 and I even forgot to check it when it wouldn't crank. I ended up cutting out the junk crimp connection and a little wired and got some good marine (I live 30 miles from the GOM) solder lugs and a good lead terminal. Been way better ever since.
I carried a 4 foot tubafour in my '67 Ford wagon for years. The cable lug on the starter would lose contact in winter temps. Key on, dash lights were bright. All accessories worked. Key to crank, not a sound. Pop the hood and poke the lug on the starter, fired right up. Toss the tubafour in back and drive on.
The older side Post Terminals on Chevy Trucks would often Corrode underneath the Terminals, everything outside looked clean but it would not allow vehicle to start, my engine just shut off at a Traffic Light. A mechanic that I knew pulled up beside me and knew what the problem was, an education for me...
Ya know Eric if you save one of us from the dreaded "A" hole status you have done a great job today. Learned a long time ago find where its good and work it to the bad. Nice repair. Thanks once again for sharing your skill and wisdom with us.
I fixed photocopiers before I retired, so I always had a bit of time to think over the customer complaint while driving to the site. That thinking led me astray many times, fixing what I thought was the problem, not necessarily the problem the machine actually had.
Corrosion & water can sure travel along wiring. I repair/install TV satellite and cable coaxial cables. I have found corroded connectors with up to SIX FEET of corroded coaxial cable. Every time I find it, I show the customer why they have no TV. It amazes them every time.
To be honest, i probably would have replaced it twice because i would have done the same preliminary check of trying to start it and seeing if the lights dim. So after the replacement starter didn't work, i would have assumed (we all know what that means) the replacement was defective and swapped it a second time. You went the smarter and less laborious route. Good find.
Had that same problem on my 96 Rav4, but i didn't have the click click. I thought it was my alternator and with family who have worked on cars going back to the stone age; we discovered that the positive side corroded from the inside out. Problem solved, nope a week later at 9pm on a dark country road, the car judt died going around a corner. Called my cousin and he thought the engine went. He jumped the car and she fired right up. Alternator bad, think God no. It was the battery. Replaced it I did and not had a problem since. Great video. Funny, it wasn't the starter nor the alternator. Ot was the battery 😊
Within the last couple of weeks, I replaced the alternator in a 1993 Chevy C1500. The original alternator was a two-wire. One wire was for the positive output of the alternator. The other small-gauge wire was the alternator's primary coil exciter feed from the idiot light on the dashboard. Replacement alternator #1 works for fifteen minutes before going dark and back to battery voltage. Same thing with replacement alternator #2 and #3. What? For #4 I go all nuts with voltage drop testing. I test each and every segment of grounding cable and positive starter and alternator cable. It all checks out. Finally, after a butt ton of Internet research, I find a data sheet for replacement alternators that states, "The primary coil wire should not exceed 1.0 amps." Well, mine is up around 1.5 amps. And this is with the old-school incandescent dash idiot light in the mix already. I source a selection of big 10 watt resistors to get the current for the exciter wire down to below 1.0 amps. And with everything set up with alligator clip leads, I take off to the auto parts store to walk them through the setup so if I fry alternator #4, they were participants. Standing there in front of the engine bay, the kid clerk asks me about the condition of the cables. I state I voltage drop tested all of them. He gets this funny look in his eye. So, I do a parking lot electrical clinic concerning voltage drop testing with a multimeter for the kid. Boy! Did his eyes light up! I told him, "You master voltage drop testing, and you'll be able to solve 90% of all electrical problems. With my add-on resistor in the alternator's primary coil exciter feed, the truck idled in the parts store's parking lot for an hour without blowing alternator #4. The current on the exciter wire was down to 0.2 amps. I'm currently 2,000 miles away from home. The 0.2 amps is too low for the battery idiot light in the dash to illuminate. This will be fine for the drive home. I'll just need to keep an eye on the dash volt meter. Once home, I'll use a 4-decade variable resistance box to dial in the necessary resistor to keep the primary exciter circuit as low as possible and still have the dash idiot light illuminate.
1.5A? That's 20W. The dash bulb shouldn't be that high. 1.5-2W. Either the bulb (not sure how) is wrong or there is some other problem. 0.2A is ~2.5W which would be really. Right even for the right bulb.
@@TheBenjammin The importance of voltage drop testing... The issues with the alternators wasn't that they were being overworked with bad resistance-loaded power and ground cables.
@@TEDodd I agree. But, until I get back home and have the time and the tools to dig into it further, it remains what it is... Short-to-power somewhere in the dash? Gonna take some more investigation, for sure, once home.
@@russellstephan6844 I'd be inclined to just disconnect the bulb and it's wires completely then. Something that broken could cause other problems. It's not working as a warning light anyway. Connect the excitation wire to the batt terminal, basic 1 wire configuration.
No, I’ll freely admit. I assumed it was the starter too. I’ll also admit I would’ve checked the battery cables for loose connections on the battery and any corrosion, but I wouldn’t have thought to look under that tape. Well, at least until I saw the smoke. This is a good lesson and not to make too many assumptions and jump on them blindly. I have to do some work on my defender tomorrow and it’s either replacing the coolant sensor or it’s a bad ground so I’m gonna replace the coolant sender because honestly they are cheap easy to access and only take a minute to do. Plus I don’t wanna screw with the grounds unless I really have to. If you want folding utility knife that opens really easy with one hand I suggest the Klein folding utility knife. It just pushed the button, flick your wrist, and it opens with no effort. Then push the button again and it folds down with just gravity.
I had a similar situation in a 2007 Civic, only intermittent. I checked all the connections, then tapped on the starter with a long extension. Each time I struck the starter it came to life. The starter was junk. I was able to change the starter with the intake on. The top bolt was stupid tight. I enjoyed the video, and learned something this morning.
Lesson learned right there.its hard to not jump right to the fix when the flat rate clock is ticking.but it could save me buying a starter .I have to tell myself to slow down to go fast.
I would have pulled and replaced the starter, put it all back together, tried starting it, click, click, clik, yelled the F word and thrown a wrench across the garage. Thanks for the lesson.
Yup, and then back to advance auto parts to give them their POS non-functional starter back to them
first, check fuses, next, check remove clean all terminal ends, 3 rd, chuck wobly.. back in 1973, i learnt, cables, earths, corrode. so now i paint, grease, oil, protect them..posative earth cars were better.. 1800,s.
LOL I am extremely accomplished at the last two, except i get well beyond the "f" word when i get up on step.
I first checked if I was getting power to the starter (obvious if you are hearing clicking though), then I might use jumper cables from the battery to the starter and see if it functions. This is more diy though, but a quick test of the starter. If it works, you know to look else where. You know the signal wire is good with the clicking, so really its battery, battery connection, or wiring.
Yep and then bought another new starter…….
That voltage drop test was awesome. Never did that before. Like they say, never too old to learn something new, even at 65.
That's is what is taught nowadays by instructors like ScannerDanner.
65? You're just a damn kid!😂 I'm coming up behind you, fast! I'm turning 40 in December and I'm still learning and trying to retain a lot if information. My father who just turned 65 once told me about working with drywall compound that if you can't get it right, the hell with it. Get out of it. Let it dry. Cone back tomorrow and sand it, and hit it again.
I remembered that as I was doing some drywall in my own house. There is a lesson in that for all of us in all aspects though. It's that in our obsession to get it done or to make it look the best today or succeed TODAY, sometimes it is best to just say "the hell with it" and take a step back, or just take a break until tomorrow when we are rested and/or refreshed and ready to give it another shot.
Sometimes doing nothing is the best course of action. Might seem counter intuitive. But if you're making mistakes and getting frustrated today, you're work is going to suffer until you are ready to focus and do your best again.
For some reason I'm really hoping for a part 2, even though it wouldn't be anything super exciting, I know.
Part II would be if the starter was also bad. Hope Eric checked it out before calling the customer and quoting just bad wires.
@@MajorMokoto yes a bad starter could have smoked a weak connection.
How hot does a Banchee get?!?
Part 2 would be a junkyard special.
I don't think I have seen him use the big crimping tool on battery cables before.
I remember a wise man who once said, "plan your work, and work the plan". Thanks for showing this. Don't jump to conclusions.
Thats what Eric just got through saying, Thanks for repeating. You got 5 clicks from it
I changed a starter on a 78 Pont Catalina in the snow, because I thought it was bad. didn't fix it. Towed to a local shop, he called before I got home, it was the ground cable. charged me $15, I was very happy with his work.
Love it when you see the magic smoke out of the cable!
The smoke test was the final straw😢😢
Starters won't work if you let the smoke out of them.

Starter clicks? Battery charged? If yes must be the starter. Didn't fix it oh well, the customer still, pays for it. What next? Battery? Ground cable? You'll be $1000 in before they check the positive cable.
I would…. But only b/c Ive been watching Eric O for many years. Dude has taught me a lot
Between Eric O. and @RainmanRaysRepairs, I've learned the value of checking power and grounds thoroughly!
Very grateful to both for sharing their work and knowledge online!
That would have been a cool one to film with the thermal imaging camera.
for sure
You are so right Eric I would of blamed the starter !!
There was one time I was helping out a fellow traveler on the road because their car would not start. I swapped out the battery (either one I had in the trunk, or the one in my car - for definitive diagnosis purposes) & cleaned (battery wire brush) the battery terminals & cables and the car started. I popped their battery back into their car & it started right up. All that was to say that the corrosion between the battery posts & cables caused enough resistance to prevent the car from starting. Ever since then I am always suspicious of battery to starter connections as a source of high resistance. Nowadays I carry a meter in the car!
Good idea.
So, I guess it's story time. This one involves a girlfriend, a 73 Camaro and corroded side post battery cables. No crank, no nothing as I remember. Unscrewed the battery cables from the battery and lots of corrosion found. Cleaned up the cables as best I could without a brush and reconnected the cables to the battery. There had been zero indication that I had corroded battery terminals. That no crank was the very first indication of trouble. The girlfriend made it home!
@@thomasshaffer8547 Yeah, back in the day you would use a knife or screwdriver to shine up the cables & terminals where they contacted each other, just scrape until the metal was shiny again.
Mr. O shows us that sometimes letting the smoke out of the wire helps speed up the troubleshooting. Great video.
As someone who has worked on Hondas for 30 years first thing i seen was that junky ass battery terminal. Hondas dont like those. Ive got bitten by those before. Just today actually with one with a turn over no start. Spent an hour on it before realizing it had that same junky ass ternimal. Gotta remember to start with the simple stuff first. Even i forget. Great video!
Eric O uses a new version of the Avoca smoker to find the problem - great lesson for us all
I thought for sure it was the starter but guess that’s why you do other test. Good job as always Mr O
When you see electrical tape on a heavy current connection it's a red flag. It didn't come out of the factory that way...
“Who let the Smoke out”….Eric O!😂
white smoke or black smoke?
Ohh noo...even it is one minute past midnight now I have to stay up and enjoy this SMA :D
My brother in law recently had nothing when he turned the key on a 2008 F150 5.4. He told me that the starter was a few months old and the battery was good. I told him not to assume either was good. I also told him to test before buying because it is stupid to put out $300 for a starter when it doesn’t fix the issue. He put a new starter on and it still did the same. I told him he could have a bad negative cable. He said it “looked good”. (You can imagine what I said). I talked him through a voltmeter and test light test and indeed it was the negative cable. He ordered a new one and his 18 year old son installed it. Fired right up after cable install.
An 18 year old son is one of the best tools you'll ever have.
@@fixerofthings HAHA YEP! They still have a back and legs that operate!
People who don't know about how cars work don't know exactly what to look for when something goes wrong. They should take a class in automotive technology, or read a book (or two) about how cars work, in addition to watching South Main Auto.
You just opened my blind eyes. Wow the multitude of things I learned from you. Thanks much
Glad to help
Picture worth a thousand words, or in this case, a video. You've coached us on the value of doing voltage drop tests and this is indisputable evidence of why it's important. Thanks for bringing us along.
Part 2?
sometimes you wonder how hot a banshee might be for something to be hotter than it
nearly as hot as a 2 dollar pistol
This was very interesting and informative. I never would have thought of checking for voltage drop first! I've replaced many starters and was lucky to fall within that 95% chance odds. Thanks for sharing this, Eric!
I'm not a particularly skilled mechanic, but I had a situation like this.... and if you are in the dark, the corroded spot will light right up so you can see it.
I enjoyed it immensely.. I had to look up how to spell it.
Fun fact: On those K24 hondoo motors, you can actually pull the starter mounting bolts and drop the starter down from underneath the motor. Then remove the solenoid wires. Saves a ton of time by not having to remove the intake plenum. It’s less of a PITA, in my experience. Great diagnostic video!
I have a 2003 Element with the same engine. Had a bad original starter after 10 years and 150K… shop replaced the starter with an aftermarket… which was bad out of the box. The shop did NOT pull the intake when they needed to replace the starter again the next day… doing that they destroyed the wiring harness to the knock sensor which is also right there. Didn’t tell me about that damage. A few years later when I needed yet another starter as the aftermarket one was dead my new non dealer Honda mechanic needed to call in a few favors to get a full harness to splice in the correct wires and connectors into the knock sensor. With time and corrosion it was throwing codes… fixed now with a Honda OEM starter. 211,000 miles on my 21 year old Element. Still love it. Best car I have ever owned.
I would’ve immediately checked the blinker fluid level. This is why I watch Eric!
We do put a ton of starters on Hondas and Toyotas but those braided ground straps on Hondas also do fall apart in our rusty areas anyway besides all the regular stuff like what happened in todays video but also don’t know why people do such poor wire and cable repairs as they cause so many problems down the road and sometimes not far down the road
I find that on toyotas, the usual starter problem is the "L" shaped contacts in the solenoid. I made some from some copper parts in about 1990, and told my friend at the dealer, who thought that was funny cause toyota sells them separately, and cheap. Now, they are even cheaper on Amazon. It's like $7 to fix them, and very easy.
Honda starters, however, seem to go through brushes.
Exactly. I've had people look at me strange when I take an hour just replacing terminal ends with copper lugs and marine terminals instead of the cheap garbage that would actually get me back on the road in 10 minutes. If you're going to do it do it right and don't have to do it again. Between the heat shrink, crimping copper terminal, and then filling the remainder of it with solder I've never had one fail.
That starter in that location with that symptom.... THAT would of caught a lot of folks... including me... and I troubleshoot multiple cars a day, taking pride in being spot on! Thanks for keeping us sharp Eric!
You are correct my friend. I enjoy these videos very much.
After about 3+ years of learning this from channels such as soutmain Auto scanner Dan western truck & tractor repair.
Knowledge is power thanks to channels like this. Much appreciated
Darn it Eric, you let the smoke out of that junk connection. Good troubleshooting once again Eric.
That era hondooo is the only manufacturer that still made a starter with very easily replaceable brushes for $13. Typical telltale sign that brushes are going bad is excessive current draw when starting. It makes it seem as if the battery is weaknor going bad because if you put a jump pack on it will seem to crank normal because you've basically doubled the cranking amps available to the starter.
the parts cannon lives another day without being fired... great job
Let that smoke out. One of the best test that I have ever seen. Good job.
Not sure if this counts on new cars, but we had a car that would turn over but not start till you let off the key. I say we, I was helping my Dad many moons ago. Anyways, best we could figure was the starter was drawin so much juice, it had none left to give a strong spark and why it would fire off just as you let off the key. Upshot was a rebuilt starter and worked good, point being, we didn't know squat about how to test for that and only figured it out by using our ears and grey matter and deduction on an old car with very few gizmo's. These new cars, boy... Glad we have Eric to show us the ropes. Thanks for the great vid!
Easy peeze, try drivability in a new car and you will get into inputs and outputs. Many mechanics will just throw parts at a car because of the variables.
Ivan would be proud of your diagnosis.
South Main Auto.. Awesome video. Very well explained Eric. That is the correct way to test/diagnose this vehicles concern.
Dragging out the tutorial to eleven minutes, and not ending with the beautiful repair you made!
I am 100% sure I would have replaced the starter. And then maybe I would have figured out the wires were bad after I got lucky and smelled the smoke that I probably would not have found.
Awesome video…again.
Luv me sum SMA video
This, everyone.... is the difference between a mechanic and a parts changer. Eric is a true mechanic.
I'm happy that you have done another basic electronics analysis and brought us in to watch it progress. Great work Eric!
Voltage drop can trick anyone when its hidden or even in plain view. So many times a headlamp was dim for no reason and the connection looked normal,,, yet she was sizzling with heat from high resistance. A simple removal and cleaning or fix of the bad terminal and it was good again. Good test there Eric using the meter for a confirmed voltage drop.
As always, much respect to Eric for taking the time and finding the issue. As for me, I would still recommend a new starter to the customer since they are very prone to failure and since I had the intake off anyway.
Yes i would love a part 2. These are my favorite type of malfunctions
I just sent it to all my techs! Thanks Eric!
For everyone crapping on mechanics who have mistakenly replaced starters in the past, MOST of the time, it is an intermittent fault. It’s easy enough to diagnose properly when then starter has failed completely, but try it when it only fails once every 3rd Sunday when the old lady is trying to go to church.
Facts, people are way too hard on mechanics when it takes a special kind of person to even be one.
I know that the standards for my repairs are different that a paid mechanic.
A paid mechanic has to fix the failing part every time, or at least most of the time. Come-backs are costly for the customer and the shop, even if it only to the shop's reputation. Replacing serviceable but worn parts both makes the shop money and avoids unrelated/coincidental failures. For failure-averse customers it's arguably money well spent.
I love to share my experience with a customer telling me he needed a starter. I found voltage drop on the negative cable and replaced the cable from the battery to the block with the negative cable on my 25 foot long jumper cables. I then went inside the car and turned the key to the sound of the engine starting i then checked the cable ends and found the end that was attached to the block had corroded so bad that the plastic cover on the cable was the only thing that supported 2 inches of that cable. I had to remove almost 3 inches of the cover on that negative cable before i found the nice copper color i was looking for. I replaced the $14 cable and bolt instead of the price of that new starter which at that time was about $80 my price. Good video as always Sir!
The church of ERIC o!!!
Tell them big man!!!
You are the best!
i would have burn through 2 starters before getting to the battery terminals, not anymore thanks to you MR O, thank you for sharing your knowledge and experience.
I learned to always wait before changing parts to check cables and connection and as you mentioned voltage drop test is a first step
Thank you for the tip.
That is a very good example of a huge voltage drop.
You can replace Honda 2.4 K starters from below without pulling the intake. It’s tight,but it can be done
Thanks again Eric for teaching all of us DA’s out here how to do something properly. I, like several others people in the comment section, would have changed that starter only to find out I was wrong…. Not that I’m gonna be changing a starter on a Honda or anything for that matter. I still change my own oil and brakes but that’s about it. I’m getting to old to do that stuff……
Great testing Erik. I might have to add that to my starter R&Rs. Voltage drop like that takes seconds with it all apart! Some shops would throw 10 starters at it, THEN send it to you!
Eric has learned- ALWAYS pay heed to that little voice in your head when it starts telling you something! It is your subconscious trying to save you from your EGO! Another great video Eric!
Thanks Eric. I'm old school and just learned something new.
Thanks for the video Eric. Great troubleshooting as usual.
Aww! I thought i was going to see soldering on a new battery terminal, a process that always brings out the critical experts on soldering.
Well, the close-up of the battery terminal crimps sent me into a full belly laugh, so yes, I did enjoy this
So, in an unrelated, slightly dumb story. Me and my father were going up north from Dutchess County to Buffalo for a family event. My father stopped off for us to take a pit stop and happened to coincidentally pulled over in your town and drove by your shop. I explained I've been watching you on RUclips for more than 5 years I think now. We drove by your shop and I looked and saw and drove down the road you always go down. It was interesting. Would have stopped off but 5pm on Friday and knowing how you feel about non customers just dropping by or calling without work needing to be done. I opted against it. I opened my mobile mechanic business modeled sort of how you do things but with my own twist. Thank you for doing a sometimes thankless job just to keep us educated and entertained.
Good find and demonstration. Plus, you saved the customer lots of money. That's worth the price of admission and why these vids of yours are so important.
This is why I always do a full visual inspection of the problem area before beginning my diagnosis, would have saved so much time here. Never don't untape the harness first.
Experience and knowledge will always prevail. Nice to have the thought process explained.
My mom has a 2007 Accord and it had several problems. The starter went bad, it currently has a bad catalytic converter, both window regulators failed at the same time, a wire broke in the door for the power windows, and another issue was similar to this case.
The car wouldn’t crank or start. I went to check the battery and found that the positive terminal was so corroded that the terminal was very thin and didn’t make good contact. I cut the terminal off, luckily the cable wasn’t corroded, and I was able to put on an aftermarket terminal and the car started and ran perfectly ever since. I was able to save money by not having to buy a new cable.
Dorrman makes better than OEM replacment rear power window regulator / motor assemblies. Both went out at about the same time on my wifes 06 Accord. I dont get anything for saying that. I just dont like doing the same repair twice on the same car if I dont have to.
Your electrical videos are my favorite! I’ve learned a lot from watching them about auto electrical ( I’m a commercial electrician)
I learnt this exact lesson at the age of 15, it was May 1st 1972, and the very first day of my official employment at the garage of a local haulage company after leaving school. The truck we were to fix was a 4 year old Ford D Series, it presented all the signs of a bad starter motor. However, before we dived in to fit new parts, the old school mechanic I was working under did a voltage drop test. Sure enough we found a full 12 volts where there should have been none. Turned out to be a poor connection on the common earth point on the chassis, this was hidden away right behind the battery. After a through cleaning, and replacing a corroded cable connection the truck fired right up. That "voltage drop lesson" stuck with me throughout my 53 years with the same company, and I myself have taught it to many new apprentice mechanics, and many an old one too. I'm retired now, but the company still owns that same old 1969 Ford D Series, it was the companies very first 'brand new' truck.
Many thanks.
David in the UK.
Electrical tape that’s not factory is always suspect
Love the vids, you the man!!
Come on Eric...I doubt anyone here would question your troubleshooting techniques!! If you didn't start there, no one would have, thanks for another lesson!
I had the exact same problem after I replaced the connection on my old F-150 and I even forgot to check it when it wouldn't crank. I ended up cutting out the junk crimp connection and a little wired and got some good marine (I live 30 miles from the GOM) solder lugs and a good lead terminal. Been way better ever since.
That bit making it smoke was the best lol of the day
Good stuff, Eric! You are an excellent teacher and the viewers are better for it!
I carried a 4 foot tubafour in my '67 Ford wagon for years. The cable lug on the starter would lose contact in winter temps. Key on, dash lights were bright. All accessories worked. Key to crank, not a sound. Pop the hood and poke the lug on the starter, fired right up. Toss the tubafour in back and drive on.
Very nice, I like the voltage drop test before taking the starter out
Because you told me to say it..... I would have checked the terminal first! Great Video, very instructional, love the test with the meter.
That is why I enjoy watching this channel.
You earned 5 stars from me amigo
The older side Post Terminals on Chevy Trucks would often Corrode underneath the Terminals, everything outside looked clean but it would not allow vehicle to start, my engine just shut off at a Traffic Light. A mechanic that I knew pulled up beside me and knew what the problem was, an education for me...
Ya know Eric if you save one of us from the dreaded "A" hole status you have done a great job today. Learned a long time ago find where its good and work it to the bad. Nice repair. Thanks once again for sharing your skill and wisdom with us.
I fixed photocopiers before I retired, so I always had a bit of time to think over the customer complaint while driving to the site. That thinking led me astray many times, fixing what I thought was the problem, not necessarily the problem the machine actually had.
Absolutely a fbomb and more moment after replacing that starter and realizing your mistake. Good catch and thank you for sharing.
Corrosion & water can sure travel along wiring. I repair/install TV satellite and cable coaxial cables. I have found corroded connectors with up to SIX FEET of corroded coaxial cable. Every time I find it, I show the customer why they have no TV. It amazes them every time.
To be honest, i probably would have replaced it twice because i would have done the same preliminary check of trying to start it and seeing if the lights dim. So after the replacement starter didn't work, i would have assumed (we all know what that means) the replacement was defective and swapped it a second time. You went the smarter and less laborious route. Good find.
Had that same problem on my 96 Rav4, but i didn't have the click click. I thought it was my alternator and with family who have worked on cars going back to the stone age; we discovered that the positive side corroded from the inside out. Problem solved, nope a week later at 9pm on a dark country road, the car judt died going around a corner. Called my cousin and he thought the engine went. He jumped the car and she fired right up. Alternator bad, think God no. It was the battery. Replaced it I did and not had a problem since. Great video. Funny, it wasn't the starter nor the alternator. Ot was the battery 😊
It’s easy to say you know the answer when you already know what the answer is. Keep em in line Eric!!
Within the last couple of weeks, I replaced the alternator in a 1993 Chevy C1500. The original alternator was a two-wire. One wire was for the positive output of the alternator. The other small-gauge wire was the alternator's primary coil exciter feed from the idiot light on the dashboard.
Replacement alternator #1 works for fifteen minutes before going dark and back to battery voltage. Same thing with replacement alternator #2 and #3. What?
For #4 I go all nuts with voltage drop testing. I test each and every segment of grounding cable and positive starter and alternator cable. It all checks out.
Finally, after a butt ton of Internet research, I find a data sheet for replacement alternators that states, "The primary coil wire should not exceed 1.0 amps."
Well, mine is up around 1.5 amps. And this is with the old-school incandescent dash idiot light in the mix already. I source a selection of big 10 watt resistors to get the current for the exciter wire down to below 1.0 amps.
And with everything set up with alligator clip leads, I take off to the auto parts store to walk them through the setup so if I fry alternator #4, they were participants.
Standing there in front of the engine bay, the kid clerk asks me about the condition of the cables. I state I voltage drop tested all of them. He gets this funny look in his eye. So, I do a parking lot electrical clinic concerning voltage drop testing with a multimeter for the kid. Boy! Did his eyes light up! I told him, "You master voltage drop testing, and you'll be able to solve 90% of all electrical problems.
With my add-on resistor in the alternator's primary coil exciter feed, the truck idled in the parts store's parking lot for an hour without blowing alternator #4. The current on the exciter wire was down to 0.2 amps.
I'm currently 2,000 miles away from home. The 0.2 amps is too low for the battery idiot light in the dash to illuminate. This will be fine for the drive home. I'll just need to keep an eye on the dash volt meter.
Once home, I'll use a 4-decade variable resistance box to dial in the necessary resistor to keep the primary exciter circuit as low as possible and still have the dash idiot light illuminate.
1.5A? That's 20W. The dash bulb shouldn't be that high. 1.5-2W. Either the bulb (not sure how) is wrong or there is some other problem.
0.2A is ~2.5W which would be really. Right even for the right bulb.
What was the point to that story?
@@TheBenjammin The importance of voltage drop testing... The issues with the alternators wasn't that they were being overworked with bad resistance-loaded power and ground cables.
@@TEDodd I agree. But, until I get back home and have the time and the tools to dig into it further, it remains what it is...
Short-to-power somewhere in the dash? Gonna take some more investigation, for sure, once home.
@@russellstephan6844 I'd be inclined to just disconnect the bulb and it's wires completely then. Something that broken could cause other problems. It's not working as a warning light anyway.
Connect the excitation wire to the batt terminal, basic 1 wire configuration.
You are the man of the hour! Thanks for the great tip! I have replaced a starter only to find that it was the cable that was rotten. You are so right.
No, I’ll freely admit. I assumed it was the starter too. I’ll also admit I would’ve checked the battery cables for loose connections on the battery and any corrosion, but I wouldn’t have thought to look under that tape. Well, at least until I saw the smoke.
This is a good lesson and not to make too many assumptions and jump on them blindly. I have to do some work on my defender tomorrow and it’s either replacing the coolant sensor or it’s a bad ground so I’m gonna replace the coolant sender because honestly they are cheap easy to access and only take a minute to do. Plus I don’t wanna screw with the grounds unless I really have to.
If you want folding utility knife that opens really easy with one hand I suggest the Klein folding utility knife. It just pushed the button, flick your wrist, and it opens with no effort. Then push the button again and it folds down with just gravity.
Great work as usual. Most people wouldn't do that voltage drop test.
Thanks Dr. O !!! I've personally been burnt from not checking the dang battery connections first and then fuses ECT! Another great video!!
I had a similar situation in a 2007 Civic, only intermittent. I checked all the connections, then tapped on the starter with a long extension. Each time I struck the starter it came to life. The starter was junk. I was able to change the starter with the intake on. The top bolt was stupid tight. I enjoyed the video, and learned something this morning.
Lesson learned right there.its hard to not jump right to the fix when the flat rate clock is ticking.but it could save me buying a starter .I have to tell myself to slow down to go fast.
