Absolutely a great tip for finding the break in a wire. Saves a ton of time and frustration. I don't know why I didn't think of doing this on my own. It's so simple! Thanks for sharing.
I am 78 years old and have worked on a lot of vehicles, but honestly that is the first time I have seen that tip with the thumb nail. Great tip indeed, yes you can teach an old dog new tricks. Just curious, what would cause those wires to break like that, it is stranded wire. I can see solid wires breaking but then again you don't see solid wires in vehicles. Thanks for sharing....Ken
it is the wire they use now in everything it as weak as a coat hanger if it bend back and forth or even vibration it breaks clean it's stranded 18 gauge wire it's all low voltage 5 volt so they use small wire cheap wire on everything
@@Rusty411 absolutely, vibration even on a small 3 cylinder engine (along with poor routing without enough strain relief) and the wires will just fatigue break in as little as 15K miles.
This is one of the best automotive videos I have seen on You tube! I am having an electrical issue with my truck now, this is how I found your video. A thousand thank yous!!!
THANK YOU BRO! This is Legendary and under rated information for real men. Cheers to all the MEN out there, we meet again! Not those "thirst" videos for simps. Just real info for real men.
Thanks Rusty , for sharing your knowledge . especially the finger nail tip . although whole video was spot on. great for helping others save on the cost of those new expensive cables !
I don't even know why I continued to watch this video to get to the thumbnail part but damn I am glad that I did. I thought it was just a video on basic continuity but that thumbnail trick is some seriously valuable stuff! Thank you very much for posting that
Awesome trick using thumb nail to locate the break in the wire and way cheaper than one of those annoying devices that beeped until it locates the break. Thank you for this gem . I've watched so many videos where they over explain everything and I end up more confused than I was before their video.
i know you say its basics. but its good to see the little tricks from the guys in the field figuring stuff out. this is why i go to you tube, to get the other guys idea and maybe save time and learn some simple stuff. thanks for the thumb nail trick. been chasing a dead wire on my boat trailer. was about to just install a new harness. but now armed with a good way. i can hopefully save some money.
Just came across this video for the first time, really helpful tip, as I am currently diagnosing some possible wiring harness failures and can't pinpoint the break based off of looks alone. Thank you for posting!
Been racking my brain for weeks trying to find the issue with my son’s 2016 Kia Soul high mount stop light and this was magic!!! Found the hidden break in the ground wire in 2 minutes!
Great bush mechanic tip. A solder joint would have been the icing on the cake but again great trick for an old dog like me. Keep up the great work. 👍🇦🇺
Thanks for the tip. I`m retired from working as mechanic in new car dealer and truck lease company. Lotta broken wires on trucks. New stuff can have bad wires from the supplier too.
I like that thumbnail trick. I had a no crank problem with my XJ after I bought it and couldn't find the problem to save my life. Finally bought a FSM and traced it down to the wire between the clutch safety switch and the starter relay. I never did find the break. Was lazy and spliced in a new wire next to the connectors and ran it through the firewall... Ain't pretty, but it still works.
Thank you my friend! You are an artist. This is once again proof positive why you should do what you love. There is a job for how you are wired. When you have an artist in any field that loves what they do, what a pleasure it is a to watch an artist at his craft! Bravo
So how do you check continuity where you don’t have access to one end? For example a wire got pulled while you were dropping the transmission and forgot to unplug a sensor but unsure if the wire was stretched to the point where it broke inside the jacket...
thanks for sharing your knowledge. its tips like this that you only learn from years of experience and understanding of your trade. much appreciated ill be sending you good vibes from texas.
Good evening my friend and nice to meet you! It's an awesome video and i enjoyed watching it. My vehicle (2003 Dodge Caravan Se V6 3.3) is giving me a (P0201-Injector Circuit/Open Cylinder 1) code and i have a (2003 POWERTRAIN DIAGNOSTIC PROCEDURES book for town & country, caravan and voyager) that shows on page 88-89 test procedures to follow and apply. So far i have applied (test 1) and (test 2) and im on (test 3) now and im stuck on not being able to follow and apply it cause im not grasping and understanding it at all. This is test 3 Turn the ignition off. Disconnect the Fuel Injector harness connector. Remove the ASD Relay from the IPM. Turn the ignition on. Jumper the Fused B+ circuit and the ASD Relay Output circuit in the IPM. (This part im lost) Using a 12-volt test light connected to ground, probe the (K342) ASD Relay Output circuit. Does the test light illuminate brightly? Yes Go To 4 No Repair the open in the (K342) ASD Relay Output circuit. Perform POWERTRAIN VERIFICATION TEST VER-5. This is a video of me following and applying (test 2-@ and in that video it shows the pages in the book from page 88-89 and pages 312-314 for code (P0201-Injector Circuit/Open Cylinder 1). Are you able to please make a video showing me how to perform all of these test procedures so it can help me grasp and understand to where im able to apply the test procedures from all those pages?
I like that trick with the thumb nail man I'm glad I watched this video now I'm about to start working on my dads old truck to fix the AC in it and we know its a wiring problem cause we changed out every thing so ill be sure to use that trick thanks man
I've got a 40 ton excavator with 10k hours .. now we're talking vibration digging in rock .. I've got some work ahead of me chasing down breaks with the codes showing up ..thanks for the info
In my experience, broken wires are pretty rare, unless it's running between moving parts, like the taillight harness to the boot lid, or speakers & window winders in doors. Opening and closing these things flexes the wire till it eventually breaks from metal fatigue. It's more an older car problem IME. The more usual continuity issue is the connection between wire & plug contacts, or the contacts themselves. If it's a high current circuit, there may have been enough heat to distort the plastic plug right at the problem contacts. So, that can be a clue, but not always. The reason for the loss if continuity between wire & plug pin is generally corrosion/oxidation of the wire or the pin. Sometimes the pin may not have been crimped tightly so the air & moisture got to the metal building up oxides between the surfacers. You can often get something working again with some Deoxit contact spray, but it's not 100% over time. Deoxit is a good product that lasts longer (often a lot longer) than most any other contact cleaner, but it's really just sweeping the problem under the carpet. If you want to preserve the original plug routing, occasionally you may be able to repair the connection but taking the pins out crimping harder or soldering the wire to the pin. However, the more sure way is cut the old pins away and install a new connector that bypasses the original plug entirely. If you want to test continuity through a plug, you can either disconnect the plug either side of the suspect one & probe the exposed contacts, or you can push sewing pins through the wire insulation & conductor & use those to probe. Just remember to remove the pins after because shorts are not fun for anyone but spectators.
Rusty, Happy new Year God bless you Sir that was an awesome way to find those breaks in the wires and reading comments you also mentioned the cheap wires been used and vibration causes as well thank you so much for this information.
Really helpful man,I have a 99 Honda 450 ES wire harness to go through.I have an idea it’s my fan wires but I’m gonna check some other stuff too so thanks for the info
1) 0:44 "on the beeps blip scale"? What did you say there? 2) This is awesome method. Does it usually work well? How many times over your career you have had to use it? It would be really awesome to hear anecdotes about you and your job, you could tell us stories!

Running 6 years now and you are still teaching us, awsome tip, will be doing this on my eng harness this weekend. Thank you sir !!
Absolutely a great tip for finding the break in a wire. Saves a ton of time and frustration. I don't know why I didn't think of doing this on my own. It's so simple! Thanks for sharing.

Vibration
One good overstressed yank will do it. The plastic cover stretched, the wire won't! Haha!
@@Rusty411 absolutely, vibration even on a small 3 cylinder engine (along with poor routing without enough strain relief) and the wires will just fatigue break in as little as 15K miles.

That was a great, practical tip. You have the best meter, Fluke. That thumbnail tip was fabulous.
A way more simple way of explaining it than any other video I’ve watched and makes a lot more sense too

Now ive got to find the break in a door harness with almost no space to work. Amazing video! Never would have guessed this !!❤
Very good tip, I see this solution first time. Thank you for sharing. Greatings from Poland, Europe!
Brilliant tip and the Southern accent made it extra special 👍🏻
Probably the best informative video in real life action, thank you for sharing this!

That’s awesome. Thanks for taking the time out to record and post it!
Good video Rusty, this testing is also useful when changing wiring harnesses when the wiring color doesn't match both sides of the plug.
So how do you check continuity where you don’t have access to one end? For example a wire got pulled while you were dropping the transmission and forgot to unplug a sensor but unsure if the wire was stretched to the point where it broke inside the jacket...
Awesome video bro been beating my head trying to find an open circuit for 2 weeks on my transmission 👍
thanks for sharing your knowledge. its tips like this that you only learn from years of experience and understanding of your trade. much appreciated ill be sending you good vibes from texas.
Thanks for the video. Trying to troubleshoot a possible broken wire on ics sensor for my atv. RUclips is great for these fix it videos.
True working man's hands...
Practical and concise tip, thank you, I will be implementing this rewiring my rv.
All those years as kid using my fingernails like that to strip small speaker wire for my stereo has finally paid off lol
Thanks for sharing!
1010 man, much appreciated, i do love having knowledge like this at my fingertips
Thats a really good trick! I've never thougt of running my nail across the wire. Thanks alot, keep up the good work man ☺
that was great thank you 3 years later
This was really helpful. Let's you know that visual inspection isn't completely enough. Thanks!
I will now forever know of this fingernail trick thanks to you. Excellent tip!
Great tip and well explained. Thanks for taking the time to do this.
Thank you for this bit of knowledge along with your helpful tips!! Very good to know!
Thanks for taking the time and effort to share this great tip.
Excellent demo. Simple but one doesn’t think for quick testing .👍
Simple but awesome tip
Never heard of this one! Good teaching. Thanks from Texas.
Great video. I am looking for a chewed wire in my motorcycle after winter storage. Your vid showed up at the top of the search ! Thanks.
Like other commentors before said, it doesn't matter how old you are you can still learn from younger people, cheers Mate, Paul UK
Excellent suggestion good communication skills, nice work.
watching it on a side of a dirt road learning how to troubleshoot this vanagon I'm broken down into. thanks for tips
I've gotta figure out how to test door wires but your "find the break" trick was pretty slick man fuck yeah
Rusty, you're an American hero.
Really smart solution! Its way harder to fix things than just replace em.
Excellent tip. Thanks for taking the time to make this.
Good evening my friend and nice to meet you!

This Guy knows his stuff. I like this guy!!!
It goes to show you that if you want to know something useful ask the man who's been doing it for years with practical experience.
You are so right as it so many people think they know it all & don't know shit
You're a smart craftsman. Great video
Great video!!!! Quick and easily explained!
Great tip if you dont have a cable tracker and the wires arent to terribly long. Thanks!
I like that trick with the thumb nail man I'm glad I watched this video now I'm about to start working on my dads old truck to fix the AC in it and we know its a wiring problem cause we changed out every thing so ill be sure to use that trick thanks man
Man. Good on you. I really appreciatie the tip. Gonna help me find a short in my boat igniting. Thanks again.
What a great way to diagnose a problem. Thank You!
I've got a 40 ton excavator with 10k hours .. now we're talking vibration digging in rock .. I've got some work ahead of me chasing down breaks with the codes showing up ..thanks for the info
That is a useful tip for that application but how do you do utilize that trick if your wires are in a harness?
Awesome tips! I'm having to wire a Linhai 300 and CRX. These tips will greatly help.
You're a legend thank you for posting this.
That video is a classic learned a lot today.
a veery good video and clear instructions, thanks. young Rusty top tips

Nice fault-finding method. Clever.
Amazing tip friend. Much appreciated.
very good video comes from a pro in his field like you master. thank you very much sir
Thank you for the tips trick used the finger thumb to find out the broken wire !!!👍👌👏
The thumbnail trick was great. Thanks for that.
Thank you for the very helpful video sir! 🫡
Great video, thanks for sharing the tip to finding broken wires.
Nice tips man thanks 😊.! I appreciate the hell out of the vid.!
Cheers mate, really helpful video. I’m trying to learn some of the basics 👍🏻
Great vid, looking for a set of these probes to test my connections on my bike, where do you get em/name of ?
Good video good sound good photography , love wiggle test and the fingernail tip test , a
Awsome thumbnail move!! Never knew. Glad for this video!!!
Love that to but what happens is there anything you could do if you can’t get the both ends like that jumper wires or something maybe
Thanks .very good stuff, never think the wire would do that.
Thank you so much you just opened up so much opportunity for me
Hope I pass my electrical ignition test
The tip with the finger nail...awesome!
Great video sir!! 👍
Thanks for this, saved me a headache
1) 0:44 "on the beeps blip scale"? What did you say there?
