I have a brushless diesel unit that lost power, I was going to just put a complete new head on it, but after watching many hours of his content I might actually try and fix it.
Hello James, I wanted to echo the positive comments from your many viewers (students). Watching you troubleshoot these problem generators and fixing the combination of normal wear, breakage, and human error is very enjoyable. Your thorough explanations of the problems with your final solutions are worthy of any technical college in the world. Thank you for taking the time to share all your knowledge and expertise!
This was the equivalent of the Electrical Murder on the Orient Express. A who done it!! Great detective work unravelling wires that were connected wrong. Just the best.
Jim, I was a GE gas turbine technician for the local utility, for over 20 years. Generators tend to be older, because they are sometimes rarely used, but the run hours are low. Therefore, many times when a part or more over, an electronic component goes bad, you find the problem you had...." not made anymore; obsolete" . TIP. : When you hit a dead end like that, call the company up, and ask to speak to a senior technician. They will usually be able to refer you to an alternate part. Once, the guy sent me a replacement / alternate part free....!!!!
Jim, I must give you accolades, for your ubdying tenacity. The way you went through that sauerkraut of wiring, and spotted the coil reversal, was amazing; Bravo....!!!!
Nice to see that your son is interested, I grew up on a farm always helping my father fixing something, to this day fixing something is my profession and hobby.
Hi Jim, I just watched this video. You were very detailed and patient. You take away much of the intimidation of working on these by process of elimination. Fatherly skills are to be commended also by letting your son be a part. Great job
I appreciate your perseverance on a very nice unit. It's tough when you have to figure out the mistakes other people have made. It's also nice that you admit your own mistakes and what you have done to rectify them. We all do it and have to back track or go a different direction..
By far my favorite of your generator repairs. I appreciated you leaving the length, showing your mistakes and following through on everything. I laughed a little, I cried a little, but really enjoyed it ;)
This is just what is needed for partial rv backup. Operates the ac and stuff perfectly. ruclips.net/user/postUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y is quieter than my rv generator. Only suggestion is that it needs a fuel shutoff valve. So it is easier to store.
Your understanding of the diodes is really good. They are everywhere nowadays. People will often hook up a battery backwards and "pop" goes the diodes...
So dense with information! You are a bit of a geek! I just learned a shit load and I’m going to watch this several times to try and absorb all of these troubleshooting strategies of yours. I work at a small engine shop at least currently I do and there is no way my boss will let me spend this much time on one unit. I showed the power was coming out of the generator and through the voltage regulator and he was happy at that point and told me to stop diagnosing! He didn’t Want me going any further. Thanks for this and nice job!
Really enjoying watching your videos, great content and excellent commentary/explanations. This kind of work has to be a real pain to film, tremendous job showing all the hard to reach places. I need lessons
Knowing how involved these things are and how touchy they can be is a good lesson for people who don't know what they're doing. Don't mess with things you don't know anything about. Find someone who does. I'm trying to figure my equipment problems with no training. I'm glad you're around!
I am trying to wrap my head around what occurred to get the wiring so wrong. The generator was so clean that it makes me wonder if someone restored it and had to rewire after taking it all apart. I always take pictures before.
I can't wait to see the next video. Being a old man an retired, I love watching these because he gets these generators in not working conditions and he fixes everything on them Correctly. A Huge Thumbs up for you Buddy. I am so glad that I found your channel the other night. God must have been smiling at me and said here you go little buddy watch this guy's videos because he and you are both perfectionist in working on stuff. Thank you all. God knows how much I love excellence. Quality videos.
@@TimHancock-h6e There is new and then there is being aware you have no idea what you are doing but do it anyway. The wise person know when he does not know.
I think messing with electrical wiring is foolish unless you know what you are doing. Its unclear why some of the wires would have been touched in the first place. I commend James for spotting the coils were mounted backwards. One thing he did not explain is why there are diodes in between the coils and the post that is connected to the ground. I believe in one of the videos James stated his dayjob, not sure if he is an engineeror computer programmer but his diagnostic skill is very good.

You are the surgeon of small engine repair :-)). Thanks agin!!
Hi I have the same generator. I injoy everything and appreciate watching you troubleshoot and figure out the problems. Watching and listening and taking good notes I'm learning. My problem is a bad rubber grommet that seals/holds the fuel shutoff valve to the fuel tank and fuel coming out of the carb. vent tube. After watching your video I feel more comfortable now getting to the carb. 👍 Thank you Don
Hi just found you ! I’ve been working on a 8000 watt deville bliss with a 14 horse vanguard. I bought it in 1999 and left it in my dads shed. Needless to say it had fuel in it so carb was trash. So I took it to a Briggs and Stratton dealer who quoted me around 700 bucks to fix ! I found clone carb on eBay less than 50 bucks and 7 bucks in fuel lines and she’s purring like a cat !
I absolutely LOVED this video. You are an excellent troubleshooter. I have an antique "DynaPro" 5500W generator (Model DP6000) that still impresses me. It uses no AVR, (you should see the simple wiring diag.), yet manages to output 126V no load, 115V full load and freq. varies only between 61-59 Hz. The old 11HP Briggs engine has a very aggressive governor that is probably the reason. Both phases AND the neutral (3 slip rings) come right off the rotating assembly (so is this called "a rotor", or "a rotating stator"?), with a stationary field...not at all how the newer ones are...
You are an inspiration because no matter the expectation, the "fix" that isn't the fix, you are not set back and just continue to analyze and diagnose. I really like your adherence to the Scientific Method.
Don G from Fla. Watched you rebuild the carburetor and then adjust the valves on one of the generators last night It gave me enough information to tackle one that has been sitting for a few years gas tank rusted out after fiddling with it for I don't know three or four hours ajusting the valves cleaning the carb rebuild it the whole nine yard got it to fire up and running and it's producing electric I just wanted to thank you I'm a subscriber now and really enjoy your videos very informative Thanks again
Watched this for a 3rd time now. Way to persist and attack each issue one step at a time. Had similar situation, the board was no longer available but Generac was able to get me a part number that would replace it made by WEN. After adding a propane adapter she has been powering my whole house thru 6 FL hurricane seasons now. Keep the great content coming.
I really liked the way you saw those diodes backwards. When you said someone had messed with that wire I didn't think so because the wire looked perfect then when you hooked the other clip on it all made sense. Those wires under the outlets were really bizarre that someone hooked the hot lead to ground. What in heavens name were they thinking. The motor looked new. Every component looked new. I bet they never used this 5 min. Good thinking on this repair you got my respect as this mess might have made me scratch my head for two months. No kidding.
Thanks. This one was a real mess. Just seemed like every time I fixed something, it was just to discover something else was wrong. Hot to ground, what could go wrong. Lucky the ground was not actually grounded.
Most of the Generator Maint. videos I watch are run of the mill (Clean them up Carb. "it runs" no power? "too bad". ) Yours go so much farther into it. I am learning a lot and I thank you so much. Mechanical I do well but the electrical, I am getting a real education.
I am the opposite. Started with carbs but got into the electrical. Slowly been getting deeper into the mechanical. Just did another Generac XG10000e that someone had wired incorrectly. Almost tricked me into thinking the power head was bad.
@@jcondon1 I got a hold of one of these a few weeks ago. The owner was selling for the motor and parts for 600 because when he took it to a shop for service he was told (after it was serviced) that the power head was bad and it was more than he was willing to pay to replace it. Other than no power, this thing was in like New Mint condition. I bought it for 300.00 after watching you fix this one. Well, it looked the same, but it was different. Had a brushless power head and no AVR. Instead I found it had TWO 25 uF Capacitors hidden in a compartment on top the power head. One was visually, obviously bad. I replaced them, put it back together and the problem was solved. Full power restored and I was one happy camper. Too bad I don't know how to send you pictures of what I found, it was like Christmas and I thought, I would have never done this without your videos. I did post some for sale pictures on Marketplace (FB- Chiefland FL).
I didn't believe the power head was bad because it was showing between 4 and 5 volts at the plug with the engine running. The two capacitors cost me $23.00 each and were shipped from China. LOL
Just got this same machine yesterday, bad stepper and probably the board also. Parts are not available, I'm just going to run it off the mechanical governor. Thank You for the video, I learned alot about the machine just watching you.
Guessing a shop gave up on it and the owner passed it on. The good condition made it easy for the sellers dishonesty to be easier to be missed. Good job staying with it!
Great learning video and appreciate your methodical diagnosis which whittles down the possibilities. Another thing which made my heart glad is your son having this record of his dad and him helping at your side... priceless! God bless you and your family.
Dude, i work as a small engine mechanic in SanDiego CA, and let me tell you that u are beating ur self up too much. U are a magnificent detective 🕵️♂️!!! U are an amazing mechanic!
James, You're the best small engine tech here on TY, BAR NONE. Great diagnostics, and careful reassembly of all mechanical aspects of these machines. Don't compare yourself to anybody else here repairing this small utility engines, the others are simply hacks.......
NICE videography !! So often, people know their subject but have shaky camera, poor sound, bad script , bad lighting ... but the shot of the loose wire was perfect. THANKS !
Jim: I have to give you much credit for working on this "CLUGE". Some one was inside the unit and screwed it up royally. You are, "One great machanic" for having the stick toerdness and patience to fix this disaster. Much credit and an "ATTABOY!!" for havinge the patience that I do not posess anymore!!
You sir are excellent at diagnostics ! :-) no doubt you know that a generator that sits for a long time looses its polarity and can be excited the way you did it . The reversed coils was an awesome catch. I think that in its self would put it out of time . Great video !!!!!! :-)
Be careful using portable generators ruclips.net/video/I1jT3ANENvI/видео.html here’s an advice about how to keep your family safe while using generators. Just hoping you stay safe
Anyone who buys a small engine should look at your video's in order to avoid the problems that you correct ..clean fuel and air and clean oil is all a small engine needs to live along life ..the most informative video's..
I just recently found your videos and they are pretty awesome. In this one, I think the reason the left side was not sparking initially was because the spark tester was grounded to the valve cover. Otherwise it probably would have acted just like the right side. Keep the videos coming!
You are a patitient man for sure. Someyimes I imagine folks are selling you badly messed up "honeypots" just for fun to freak you out, but you pull it through every freakin' time - hah! Love your videos, they have become my favorites, really appreciate your calm and always analyzing attitude..
Wow, good work figuring that out. Wish I had that much understanding about the electrical side. Now with your profits would you please buy yourself a small lift so you aren’t working on the ground all the time. It will be the best investment. My back hurts just watching your videos.
Holy smokes, kudos to you for sticking with this comedy of errors until the very end ! At first , I wasn't going to watch the video due to its length, but I was intrigued with your trouble shooting skills and professionalism so I stuck with it. Thank you very much. Also enjoy the audio and video quality of all of your videos. : )
That is one of the cleanest generator engines i've seen in a couple of years. The only electrical work i do on generators is replace the outlets. I never touch the wiring itself
This is the A #1 generator learning channel on you tube. The absolute BEST! I've got to look at the electrical portion again. You have got to be or have had electrical/mechanical engineering training. I am mesmerized with your ability to SNIFF out problems. You need to consider a new RUclips ID "THE GENERATOR BLOODHOUND" I enjoy the videos, I am proud to see that you have your son there with you. He will be eternally grateful for your knowledge that you can teach him.
Nice projects! Thank you! I don't think there is a residual magnet. The excitation is from an external source. There is no excitation which is why the output voltage is so low. I have to reach way back for this information but I think that it is accurate! The excitation is D.C from an AC source which is why the Rotator has commutator segments! The banded end of the diode is the negative cathode end! Ron
I have been going through your videos and I am learning quite a lot about these 3600 RPM generators. I have my father’s “old” DeVilbiss PowereBack 5250 generator that he bought quite a few years back; perhaps sometime in the ‘90s. I crank it up from time to time just to keep it lubricated and check it out. It still runs fine, although the output voltage is a little bit on the low side, but nothing excessive. After watching your videos, I decided to check the frequency and discovered that it was low. I increased the engine speed and got it up to where it should be. This was something I had not previously considered checking on, thanks. I recently checked it out prior to the upcoming hard freeze that we had in February, but even though the state had rolling blackouts, living a couple of blocks from a hospital, we never experienced any outages. However, we know of some people that were down for as much as eight hours. During the freeze, we were all asked to minimize our power usage as much as we could. This got me thinking how much do we use? I have already changed out all of our lights from incandescent to first CFL and more recently LED bulbs. Our house uses a gas furnace, and is well insulated. So I really could not think of any heavy loads in use. We did not do any laundry during this time and the microwave in only on for 1 -2 minutes several times a day, so I could not see where we were using that much power. So to answer my question, I went to the main panel, took the cover off, and using my current clamp meter, I measured the current draw on the two legs coming into the panel. I was shocked to see that on one leg I was pulling 5.3A and the other was 3.7A. This was less than what some toaster pull. Granted, at the time of my readings, the furnace was not on (the blower motor does pull around 10A) and the microwave was not in use, but still, was astounded to see how little we were using. In fact, I turned on a couple of known devices to check my meter to verify it was correct. So this has got me thinking about a 12KW (or greater) whole home generator. The most obvious solution would be to install a Generac unit, but because of this video, I am also considering a portable unit like the ones you work on. This would not only be a cheaper solution, but also simpler to install. If I needed to replace the unit somewhere down the road, I would just buy the unit and there would be no installation cost involved. So here is the reason for my post. While you primarily focus on repairing broken units, you might want to consider making a video (or several) discussing the various units out there. The pros and cons of various styles, features, and most importantly, what to watch out for. You might want to also touch on maintenance, service, and other factors for maximizing the service life of the unit. Also, tips on considering the purchase of used units versus new units. Anyway, thanks for your videos, I have learned a lot and have come to have a higher respect for these 3600, 2-pole generators. I had not considered these as anything other than work site units, primarily due to the high RPM, and air cooled “lawn mower” engines. But with a sound reducing enclosure, and venting, I could see this as a viable alternative during hurricane season, which is my main concern. Thanks again for your videos.
Unfortunately most generators run at 3600 rpm. The 1800 RPM units are a million times more quiet. Even the installed hole house Generac generators run at a screaming 3600 rpm (but they are enclosed so much more quiet). I use an inverter generator for my house, but am limited on the power. They produce very clean power and max out around 7000 watts. That said they can produce up to 58 continuous amps which can do a lot (but not all at once). The portable units cost a lot less and are available up to about 22000 surge watts.
Wow what a great video!!! I learned a lot THANKS SO MUCH I HAVE A PARTS GENERATOR THAT I THE EXACT ONE YOU GOT THAT USED BOARD FROM I converted my 6500 generac 6500 mega force to electric start!!!
I'd check the resistance of each winding, the part of the outlet that looks like it has a 90 degree off it is the ground. The residual field u got from flashing,makes voltage in the stator, part of that goes to the AVR auto volts reg. and sends a certain amount of voltage to the brushes , could be a.c. then gets rectified to d.c. for the rotor excitation.
After watching several of your videos, I'm astounded that there are not more reports of people being killed by generators (and not by carbon monoxide). Great job fixing all the botched work!
Sad so many people have Screwed the equipment up and then declared it cant be fixed and is Junk. meanwhile owners are trusting these people to fix or maintain stuff. Our country is Screwed. Not many thorough guys like you. Thanks John
FYI, bayonet lugs on coil wires that become disconnected from the high tension wire have a real tendency to smoke the solid state circuitry in a lot of coils. It is probably due to the coil voltage exceeding the PIV rating of the internal circuitry in the coil. I have found this is a real problem in two cycle chainsaws.
This was a very good video. I have watched several of your videos in an attempt to learn how to fix my own. With your help I now have four working generators. A Mikuni for the Subaru EX30 was giving me fits. Also a Nikki on a B&S 10HP, Thanks to your videos They all purr now.
Good job sir, you're thorough and meticulous and it paid off with this generator! If you decide to sell this machine I hope you turn a nice profit, you surely earned it!
When I remove carburetor jets I use screwdrivers that are machined and not molded like a regular screwdriver. I own the Briggs jet screw screwdrivers but gunsmithing screwdrivers work well or even one of the 4in1 screwdrivers from harbor freight work well. Quite often if I find them stuck I will firmly hit them with a small ball peen hammer. Good luck and thanks for the videos.
Enjoyed every step of the way. The electrical troubleshooting is my weak point on these things. It really irks me also that when trying to repair these things the manufacturer discontinues key parts like the power board or even something simple like the muffler. I like the Generac generators from the EX 7000, 7550, and 8000 Power range. They are tough and last a long time but a lot of the parts are no longer available.
Nice work. I buy non working gensets, repair them for resale as well. The older Generacs are nice machines, but the AVR’s and system control boards are expensive, proprietary and can be hard to find. I generally stay away from these older generacs because of this reason. Love the drill trick, I get a thrill every time it works and have bought gensets in which that was the only problem. Theses are a lot of fun to work on. I stick to the Honda clones with traditional AVR’s because parts are plentiful and cheap.
I try and stay away from ones like this for the same reason. Its disappointing that they do not make that PCB anymore or at least share the circuit board design under the potted material.
@@jcondon1Couldn't the public be soaked in something to dissolve/loosen the potting material? Once issues corrected apply new potting material to finish? Seems like when there is a will there is a way.
I always feel encouraged watching your videos...... I have some nightmare repair projects (Electronics)....... and seeing that I'm not alone having to take something apart a dozen times does me good
Great video, thank you. Just loved your thought processes, you could hear the cogs turning, well done. Greetings from the UK, a small island off the coast of Europe. 😀
You are a genius, the best videos I have ever seen keep up the good work and get yourself a work table I can’t see you working on the floor. Thank for for sharing your knowledge.
Awesome video, I watched it like I was watching a movie on tv, closely following it every step of the way awaiting the final scene. Looking forward to more of your videos.
As the old guy says "The hardest part about fixing any machine is to first find the faults introduced by the "other guy", then you can set about finding out what's actually wrong with it!".... This all reminds me of 20 to 25 years ago, when I used to go with my dad to collective and dispersal sales. We bought a fair few generators (amongst other machines) to haul home to fix up and turn around for resale. There were some machines that just were not going to play ball, and a lot that had been butchered to the point of not even worth bidding on. Sadly, we lost my dad in February 2008, but we still have some of those machines around the yard, and until CoViD came along, still got to some of the sales. Well, I think that Generac turned out well in the end, but I began to wonder if you were developing a fetish for taking that fan shroud off that engine! We don't see many Generacs over here, more SDMO and CHonda clones, a few Suzuki, genuine Hondas, and the odd Yamaha or two and a smattering of domestic makes and models.
I would definitely feel more confident buying a used generator from this dude than buying a new one. This guy is a guru for sure.
I agree, at least you would know that it's the best it could possibly be
I have a brushless diesel unit that lost power, I was going to just put a complete new head on it, but after watching many hours of his content I might actually try and fix it.
.@@a-k-jun-1
Except if you buy a Honda generator. Even James has one & his like mine has never required service.
Yes, I agree. And, though I will never have the skills & knowledge, I will at least know how to store my machine, and take care of it!😎❤️
Not going to lie, these videos are strangely addictive
Thanks!
Very informative if not educational
Aren't they?!
Yes they are.
They are well made and show what pride in your work looks like.

Hi
I have the same generator. I injoy everything and appreciate watching you troubleshoot and figure out the problems. Watching and listening and taking good notes I'm learning.
My problem is a bad rubber grommet that seals/holds the fuel shutoff valve to the fuel tank and fuel coming out of the carb. vent tube.
After watching your video I feel more comfortable now getting to the carb.
👍
Thank you
Don
Picked up the same generator from a buddy cuz he couldnt get it running. Turns out the carb had come loose. Great score!
Just now saw this video Doc., I was on the edge of my seat for this one, it was challenging. Learned alot.
lol, it is one of my favorites.
You sir are one of the best keep secrets on RUclips ! Keep the videos coming ! From a new subscriber. You showed great patients & determination.
Thanks! I think RUclips woke up.

You are an inspiration because no matter the expectation, the "fix" that isn't the fix, you are not set back and just continue to analyze and diagnose. I really like your adherence to the Scientific Method.
Don G from Fla. Watched you rebuild the carburetor and then adjust the valves on one of the generators last night It gave me enough information to tackle one that has been sitting for a few years gas tank rusted out after fiddling with it for I don't know three or four hours ajusting the valves cleaning the carb rebuild it the whole nine yard got it to fire up and running and it's producing electric I just wanted to thank you I'm a subscriber now and really enjoy your videos very informative Thanks again
Thanks. Glad to hear you were able to get it running.
Would you say it's inspiration also?
Watched this for a 3rd time now. Way to persist and attack each issue one step at a time. Had similar situation, the board was no longer available but Generac was able to get me a part number that would replace it made by WEN. After adding a propane adapter she has been powering my whole house thru 6 FL hurricane seasons now. Keep the great content coming.
I really liked the way you saw those diodes backwards. When you said someone had messed with that wire I didn't think so because the wire looked perfect then when you hooked the other clip on it all made sense. Those wires under the outlets were really bizarre that someone hooked the hot lead to ground. What in heavens name were they thinking. The motor looked new. Every component looked new. I bet they never used this 5 min. Good thinking on this repair you got my respect as this mess might have made me scratch my head for two months. No kidding.
Thanks. This one was a real mess. Just seemed like every time I fixed something, it was just to discover something else was wrong. Hot to ground, what could go wrong. Lucky the ground was not actually grounded.
Most of the Generator Maint. videos I watch are run of the mill (Clean them up Carb. "it runs" no power? "too bad". ) Yours go so much farther into it. I am learning a lot and I thank you so much. Mechanical I do well but the electrical, I am getting a real education.
I am the opposite. Started with carbs but got into the electrical. Slowly been getting deeper into the mechanical. Just did another Generac XG10000e that someone had wired incorrectly. Almost tricked me into thinking the power head was bad.
@@jcondon1 I got a hold of one of these a few weeks ago. The owner was selling for the motor and parts for 600 because when he took it to a shop for service he was told (after it was serviced) that the power head was bad and it was more than he was willing to pay to replace it. Other than no power, this thing was in like New Mint condition. I bought it for 300.00 after watching you fix this one. Well, it looked the same, but it was different. Had a brushless power head and no AVR. Instead I found it had TWO 25 uF Capacitors hidden in a compartment on top the power head. One was visually, obviously bad. I replaced them, put it back together and the problem was solved. Full power restored and I was one happy camper. Too bad I don't know how to send you pictures of what I found, it was like Christmas and I thought, I would have never done this without your videos. I did post some for sale pictures on Marketplace (FB- Chiefland FL).
I didn't believe the power head was bad because it was showing between 4 and 5 volts at the plug with the engine running. The two capacitors cost me $23.00 each and were shipped from China. LOL
Out of curiosity, what was your asking price for the one you had or did you keep it?
As you reconnected the electric start lead with your vice grips, I literally said "That's not going anywhere" just before you did, lol.
Great channel. Very helpful I just picked up a generac centurion 15kw with lots of work needed,
can’t beat free. This video is exactly what I needed.
Free is the best. Takes the pressure off. Nothing worse then paying money for something broken just to discover it cannot be fixed.
Just got this same machine yesterday, bad stepper and probably the board also. Parts are not available, I'm just going to run it off the mechanical governor. Thank You for the video, I learned alot about the machine just watching you.
Someone tried to restore that generator, and did a great job on 97% of it all. You went in and found all their mistakes. Another great video.
Guessing a shop gave up on it and the owner passed it on. The good condition made it easy for the sellers dishonesty to be easier to be missed. Good job staying with it!
a man is never too old to learn something new even when i doo repairs on small engines i still stands out to learning more
Great learning video and appreciate your methodical diagnosis which whittles down the possibilities. Another thing which made my heart glad is your son having this record of his dad and him helping at your side... priceless! God bless you and your family.
Thanks!
You deserve a medal for this one! 🎖 Excellent works/skills!!
James you can indeed make a silk purse out a sows ear. Your knowledge and skill has no end, well done with this one.
After traking about 40 videos from this channel, i'm can declare, this was a challenge ))))
Dude, i work as a small engine mechanic in SanDiego CA, and let me tell you that u are beating ur self up too much. U are a magnificent detective 🕵️♂️!!! U are an amazing mechanic!
Thanks, appreciate that.
James, You're the best small engine tech here on TY, BAR NONE. Great diagnostics, and careful reassembly of all mechanical aspects of these machines. Don't compare yourself to anybody else here repairing this small utility engines, the others are simply hacks.......
NICE videography !! So often, people know their subject but have shaky camera, poor sound,
bad script , bad lighting ... but the shot of the loose wire was perfect. THANKS !
Thanks. Been working on the light, sound and camera angles. My early videos suffer from all those issues.
I have been watching a lot of your older vids . ENJOYING them as much as the first watch !
Jim: I have to give you much credit for working on this "CLUGE". Some one was inside the unit and screwed it up royally. You are, "One great machanic" for having the stick toerdness and patience to fix this disaster. Much credit and an "ATTABOY!!" for havinge the patience that I do not posess anymore!!
You sir are excellent at diagnostics ! :-) no doubt you know that a generator that sits for a long time looses its polarity and can be excited the way you did it . The reversed coils was an awesome catch. I think that in its self would put it out of time . Great video !!!!!! :-)
Be careful using portable generators ruclips.net/video/I1jT3ANENvI/видео.html here’s an advice about how to keep your family safe while using generators. Just hoping you stay safe
Anyone who buys a small engine should look at your video's in order to avoid the problems that you correct ..clean fuel and air and clean oil is all a small engine needs to live along life ..the most informative video's..
These videos are informative, educational and most significantly, they are for real. Troubleshooting is tricky and this is how its done. Hat off!
Thanks
I just recently found your videos and they are pretty awesome. In this one, I think the reason the left side was not sparking initially was because the spark tester was grounded to the valve cover. Otherwise it probably would have acted just like the right side. Keep the videos coming!
Fantastic work James, really enjoyed this and all your videos. I liked how you resolved the issues with this generator.
Great video and troubleshooting skills! I'm impressed! Would have liked to see how you mounted that board though. Keep them coming!
You are a patitient man for sure. Someyimes I imagine folks are selling you badly messed up "honeypots" just for fun to freak you out, but you pull it through every freakin' time - hah! Love your videos, they have become my favorites, really appreciate your calm and always analyzing attitude..
I sometimes wonder the same thing.
Wow, good work figuring that out. Wish I had that much understanding about the electrical side. Now with your profits would you please buy yourself a small lift so you aren’t working on the ground all the time. It will be the best investment. My back hurts just watching your videos.
Would like a lift table, but find it is easier to record and see what I am recording if on the ground. Will get one eventually.
I ordered a lift table for this exact type of work. It will elevate up to 40 inches...
gentil man I like your video but one more thing can you diagnose that your front shoes are open and the winter is coming son sir
That has to be the cleanest molested generator I've ever seen.
Agreed. Looks new! But someone had their way with it.
I like the way you go about problem solving and editing. I'm addicted,lol
Holy smokes, kudos to you for sticking with this comedy of errors until the very end ! At first , I wasn't going to watch the video due to its length, but I was intrigued with your trouble shooting skills and professionalism so I stuck with it. Thank you very much. Also enjoy the audio and video quality of all of your videos. : )
Thanks
That is one of the cleanest generator engines i've seen in a couple of years. The only electrical work i do on generators is replace the outlets. I never touch the wiring itself
You are a true genius! Incredible patience. Awesome outcome. Thank you once again. Love and blessings from Ontario Canada.
You do fine work! You really give a good narrative of how and don’t even throw a wrench!
Lol
Thanks 👍🏻💞❤️
This is the A #1 generator learning channel on you tube. The absolute BEST! I've got to look at the electrical portion again. You have got to be or have had electrical/mechanical engineering training. I am mesmerized with your ability to SNIFF out problems. You need to consider a new RUclips ID "THE GENERATOR BLOODHOUND"
I enjoy the videos, I am proud to see that you have your son there with you. He will be eternally grateful for your knowledge that you can teach him.
My day job involves database programming and coding. Involves a lot of problem solving.
Nice projects! Thank you! I don't think there is a residual magnet. The excitation is from an external source. There is no excitation which is why the output voltage is so low. I have to reach way back for this information but I think that it is accurate! The excitation is D.C from an AC source which is why the Rotator has commutator segments! The banded end of the diode is the negative cathode end! Ron
10k continuous. Wow that's a nice compact unit for it's capabilities!
I have been going through your videos and I am learning quite a lot about these 3600 RPM generators. I have my father’s “old” DeVilbiss PowereBack 5250 generator that he bought quite a few years back; perhaps sometime in the ‘90s. I crank it up from time to time just to keep it lubricated and check it out. It still runs fine, although the output voltage is a little bit on the low side, but nothing excessive. After watching your videos, I decided to check the frequency and discovered that it was low. I increased the engine speed and got it up to where it should be. This was something I had not previously considered checking on, thanks.
I recently checked it out prior to the upcoming hard freeze that we had in February, but even though the state had rolling blackouts, living a couple of blocks from a hospital, we never experienced any outages. However, we know of some people that were down for as much as eight hours. During the freeze, we were all asked to minimize our power usage as much as we could. This got me thinking how much do we use? I have already changed out all of our lights from incandescent to first CFL and more recently LED bulbs. Our house uses a gas furnace, and is well insulated. So I really could not think of any heavy loads in use. We did not do any laundry during this time and the microwave in only on for 1 -2 minutes several times a day, so I could not see where we were using that much power. So to answer my question, I went to the main panel, took the cover off, and using my current clamp meter, I measured the current draw on the two legs coming into the panel. I was shocked to see that on one leg I was pulling 5.3A and the other was 3.7A. This was less than what some toaster pull. Granted, at the time of my readings, the furnace was not on (the blower motor does pull around 10A) and the microwave was not in use, but still, was astounded to see how little we were using. In fact, I turned on a couple of known devices to check my meter to verify it was correct.
So this has got me thinking about a 12KW (or greater) whole home generator. The most obvious solution would be to install a Generac unit, but because of this video, I am also considering a portable unit like the ones you work on. This would not only be a cheaper solution, but also simpler to install. If I needed to replace the unit somewhere down the road, I would just buy the unit and there would be no installation cost involved.
So here is the reason for my post. While you primarily focus on repairing broken units, you might want to consider making a video (or several) discussing the various units out there. The pros and cons of various styles, features, and most importantly, what to watch out for. You might want to also touch on maintenance, service, and other factors for maximizing the service life of the unit. Also, tips on considering the purchase of used units versus new units.
Anyway, thanks for your videos, I have learned a lot and have come to have a higher respect for these 3600, 2-pole generators. I had not considered these as anything other than work site units, primarily due to the high RPM, and air cooled “lawn mower” engines. But with a sound reducing enclosure, and venting, I could see this as a viable alternative during hurricane season, which is my main concern. Thanks again for your videos.
Unfortunately most generators run at 3600 rpm. The 1800 RPM units are a million times more quiet. Even the installed hole house Generac generators run at a screaming 3600 rpm (but they are enclosed so much more quiet). I use an inverter generator for my house, but am limited on the power. They produce very clean power and max out around 7000 watts. That said they can produce up to 58 continuous amps which can do a lot (but not all at once). The portable units cost a lot less and are available up to about 22000 surge watts.
Watching you Holmesing a problem has helped me think through things.Many thanks.
Thank you, Generator Whisperer
That's a really nice generator, right there. Beautiful original condition, American-made. Sounds beefy.
This is the best made generator I have ever worked on.
Wow what a great video!!! I learned a lot THANKS SO MUCH I HAVE A PARTS GENERATOR THAT I THE EXACT ONE YOU GOT THAT USED BOARD FROM I converted my 6500 generac 6500 mega force to electric start!!!
your electrical expertise and most of all .....patience is commendable!
Thanks
I'd check the resistance of each winding, the part of the outlet that looks like it has a 90 degree off it is the ground. The residual field u got from flashing,makes voltage in the stator, part of that goes to the AVR auto volts reg. and sends a certain amount of voltage to the brushes , could be a.c. then gets rectified to d.c. for the rotor excitation.
After watching several of your videos, I'm astounded that there are not more reports of people being killed by generators (and not by carbon monoxide). Great job fixing all the botched work!
Thanks
Sad so many people have Screwed the equipment up and then declared it cant be fixed and is Junk. meanwhile owners are trusting these people to fix or maintain stuff. Our country is Screwed. Not many thorough guys like you. Thanks John
FYI, bayonet lugs on coil wires that become disconnected from the high tension wire have a real tendency to smoke the solid state circuitry in a lot of coils. It is probably due to the coil voltage exceeding the PIV rating of the internal circuitry in the coil. I have found this is a real problem in two cycle chainsaws.
Nice detective work, good to have a accurate schematic to follow , had a lot working against you ! Thanks for sharing !
This was a very good video. I have watched several of your videos in an attempt to learn how to fix my own. With your help I now have four working generators. A Mikuni for the Subaru EX30 was giving me fits. Also a Nikki on a B&S 10HP, Thanks to your videos They all purr now.
Glad to hear. The Mikuni’s always fight me. Easy to get them 95% but hard to get them perfect.
Good job sir, you're thorough and meticulous and it paid off with this generator! If you decide to sell this machine I hope you turn a nice profit, you surely earned it!
When I remove carburetor jets I use screwdrivers that are machined and not molded like a regular screwdriver. I own the Briggs jet screw screwdrivers but gunsmithing screwdrivers work well or even one of the 4in1 screwdrivers from harbor freight work well. Quite often if I find them stuck I will firmly hit them with a small ball peen hammer. Good luck and thanks for the videos.
Enjoyed every step of the way. The electrical troubleshooting is my weak point on these things. It really irks me also that when trying to repair these things the manufacturer discontinues key parts like the power board or even something simple like the muffler. I like the Generac generators from the EX 7000, 7550, and 8000 Power range. They are tough and last a long time but a lot of the parts are no longer available.
The starter fluid idea was brilliant it started my generator
I just found your Site….thank you for how you explain in detail the things your doing….really like learning something new.
Nice work. I buy non working gensets, repair them for resale as well. The older Generacs are nice machines, but the AVR’s and system control boards are expensive, proprietary and can be hard to find. I generally stay away from these older generacs because of this reason. Love the drill trick, I get a thrill every time it works and have bought gensets in which that was the only problem. Theses are a lot of fun to work on. I stick to the Honda clones with traditional AVR’s because parts are plentiful and cheap.
I try and stay away from ones like this for the same reason. Its disappointing that they do not make that PCB anymore or at least share the circuit board design under the potted material.
@@jcondon1Couldn't the public be soaked in something to dissolve/loosen the potting material? Once issues corrected apply new potting material to finish?
Seems like when there is a will there is a way.
PCB
You know your electrical stuff. And u are a dang good small engine tech.
Nice work on that gen.
Thanks!
This is the best video yet. You're the goat in this line of work. Thank you!

Just finished watching, covered quite a few issues, very thorough,
Thanks Jim
Thanks
I always feel encouraged watching your videos...... I have some nightmare repair projects (Electronics)....... and seeing that I'm not alone having to take something apart a dozen times does me good
I can imagine. Wish I was better with that.
Man, this was a tough one. Great job done!
Well Explained. Excellent training and trouble shooting. I Will watch again, as I work on generators, to help trouble shoot the systems.
Thanks!
Great video, thank you. Just loved your thought processes, you could hear the cogs turning, well done. Greetings from the UK, a small island off the coast of Europe. 😀
You are a genius, the best videos I have ever seen keep up the good work and get yourself a work table I can’t see you working on the floor.
Thank for for sharing your knowledge.
Great show I watch for hours and I do watch for hours some people are really knowledgeable keep them coming
Awesome video, I watched it like I was watching a movie on tv, closely following it every step of the way awaiting the final scene. Looking forward to more of your videos.
As the old guy says "The hardest part about fixing any machine is to first find the faults introduced by the "other guy", then you can set about finding out what's actually wrong with it!".... This all reminds me of 20 to 25 years ago, when I used to go with my dad to collective and dispersal sales. We bought a fair few generators (amongst other machines) to haul home to fix up and turn around for resale. There were some machines that just were not going to play ball, and a lot that had been butchered to the point of not even worth bidding on. Sadly, we lost my dad in February 2008, but we still have some of those machines around the yard, and until CoViD came along, still got to some of the sales.
Well, I think that Generac turned out well in the end, but I began to wonder if you were developing a fetish for taking that fan shroud off that engine! We don't see many Generacs over here, more SDMO and CHonda clones, a few Suzuki, genuine Hondas, and the odd Yamaha or two and a smattering of domestic makes and models.
I just went through the same overhaul . A beast it is. I ended up selling it because of the weight.
I saw one here near me ....he converted it into a tri fuel generator....he wants 1600....i think that too much? What do you think
@@rockystelone21 for that age, yes.
@@MrReadandlearn brother thats all i need to know ....thank you!
Wow great job! Undoing someone else's mess can be the most challenging thing to face!
Thanks, though it was a simple case of old fuel. Boy was I wrong.
If it's a James Condon video where wrenches are turning and sparks are being chased I click on it. This was a good one. Thanks for posting. 😉
