Holding on to the generator until the video paid for the part is genius. You basically get the part for free, sell the generator, and everything you make from here is profit. This generator is valuable enough to wait on. That is a great idea. I really need to get my channel started. I have done some filming, but I don't have a great camera, computer, or the proper editing software yet. I have enough machines already to keep me busy for a year or so. I really need to get started.
Only a youtuber ever thinks about that. The cheapest cameras today are "good enough" YOU are FAR, FAR more important than your equipment. I could give you a million dollar camera and if you don't pay attention to things like lighting and angle, all that million dollar gear will not help. I can give you a low end, but OK camera and if you do everything physical correctly, nobody will ever be the wiser. Mustie1 is a great example. The guy buys his cameras at flea markets and uploads in 1080 or 720 and his video is great. NEVER a complaint from me. The computer is really where you need the power. But I am pretty sure it is FAR more dependent on your video card than the processor. Also, it doesn't take awesome equipment for audio, but it is incredibly easy to screw up audio;.
As a low end you-tuber I can tell you it is all about the content, I have had many camera setups to suit budget but because of my location I can't earn money from YT as the partner program does not support my country, I do not have a very high subscriber count but that does not bother me..... I am here to teach and that is it. It is all about your mindset. Just do what your goal is and forget the rest, those that like will watch and if the content is good they will sub.... Just get a decent lapel mic and for the most part you can use your cell phone to video with, most of todays cell phone cameras have more than enough resolution for the normal person to make 1080p videos with.......
Well you just saved me time and money by making me realise my decision just to drop $1k on a brand new inv / gen was the right call. I won't bother trying to fix my old one. Thank you very much!
James, this is why I like viewing your post. You always give cost analysis and part availability when you find the issue on repair. Keep posting as I do enjoy them on your findings and repair. Michael
What's crazy is he held on to the generator till the videos paid for the part. What's even crazier is now that it's fixed he can sell it and still make money on this thing even after it's gone great job and awesome videos thank you for all you do and keep us entertained.
James, really high-five you on this one. A year into the making, production and outcome. Perseverance here paid off, no pun intended. But, it's your perseverance here that I want to applaud. Many, many would kick this to the curb. You stayed steadfast, positive and waited for the videos to turn the profit margin around. I'm glad you kept with it. The end product was success and hopefully the continuation of Likes garners you the deserved profit. Really enjoyed watching all three vids. Job well done Young Man!
I have an old Chicago 5500 W generator that was given to me by a friend about 7 years ago. They couldn't get it to run. But a little clean up and I got it running. It's been helping me through power problems, even 10 days without power one time. The last time I had it running 3 days after a power outage and the power became erratic. Of course when a major storm comes through a wide area. All the generators vanish at stores. But I located a 7.5KW Predator Inverter machine and finished the outage using it. The power was super clean. But I had no idea how clean. I'd been looking though your videos for a inverter gen repair and here it finally is. This makes my choice in picking such a machine up a winner. Thanks so much for seeing this through. As for the old generator, your videos have inspired me to see if I can restore it to full operation. Only thing better than having one generator is having 2 in case one breaks down. Cheers!
Nice Gen-Set! I love Honda's and Yamaha's. They are very quiet and "usually" a trouble free machine if taken care of. Well done James! Looking forward the the EU2000 Honda repair!!
I love the fact it did not end up in the land fill. That sir is my favorite part of all your videos - and you recycle parts when you can, ALSO a massive plus. Love ALL your videos!
Very clean output from that unit . I am on the fence with the sub economic repair tho . For the typical owner , TH-cam revenue is not a realistic option , so you are fortunate in that regard . No surprise though . Your content is very good and your troubleshooting skills are top drawer .
if it were mine, and I knew it's operational history, and a good used replacement is around $900, making my own good used replacement where I knew the most expensive part was brand knew, I'd do the repair. For someone repairing and reselling, makes no sense to repair.
I'm so glad to see this Part 3 with a replacement inverter board! I was wondering if you would ever locate a used board to get this running again. This model Yamaha was rare to begin with.... and now OLD and RARE. Brilliant idea with the revenue to order a new board! Great fix. That Amprobe with THD is awesome for the price too. I might have to get that.
Well that was nothing short of war ! Inverters give nice clean power. However if you can get by without it and are working on a tight budget I'd advise staying away from them, especially if it's old. Newer models have probably come on somewhat.. A great series of videos. Glad James pushed on and got it fixed. It was good as an exercise to guide others even if not very financially viable.
Great job James on the repair! Way to close the loop on it! I too would have been wanting to fix it even though it was very costly. The THD is extremely good, but I be curious to the transistor MOSFET noise. That's up in the 20K to 50K Hertz range sometimes higher. When you get more familiar with your oscilloscope it has an FFT function where you can see the entire frequency spectrum. Be curious to see if there are any noise spikes up in that high range. It should be pretty low considering the filtering to where it won't be a problem. That's one of the things I'm going to do with my Yamaha EF 2000 IS at some point.
I'm glad you repaired this unit, especially considering you could have easily parted it out and probably made more money in the process, excellent job James
I’ve got the 3500 iseb version of this. I believe it’s identical other than it uses the battery for a 500w “boost”, thus the b in the model. We use primarily for our camper and that boost works well for a/c start up load. We also use it for back up at the house. Does everything except run the 240v well which we have a bigger unit for. Really come to love the yami generators after owning this one for a while.
Random free advice: if you plan on running your generator in temperatures below freezing in an area without a lot of dust or dirt, remove your air filter, and your crankcase breather tube from your intake, the breather vents the warm crankcase fumes from the bottom of the engine, but there is always moisture inside the crankcase unless it is only serviced and oil added in extremely dry conditions, 99% of the time there is moisture in the air during the oil addi g or changing procedure, this let's water in tiny amounts into the crankcase, as the generator heats up this turns to water vapor, and when sucked into the intake(the coldest part of the generator when operating in sub freezing temperatures) it condenses on the air filter foam and can cause carburetor icing problems whe running, and then after the generator is shut down, this freezes inside the foam air filter and the next time it is needed, the air filter is a frozen block of ice, which can cause lots of running problems and voltage output fluctuations. General rule is this: if there's no dust or dirt present in the location of the generator, then the air filter assembly and breather tube will cause more problems than they will solve. P.s. put a small disposable cup or jar under the disconnected breather tube to keep oil from spilling around the generator, this is usually clean oil and can be reused in the crankcase unless heavily contaminated by water which will present itself as a white residue in the oil. Just thought I'd pass that tidbit of advice along from the frozen north of Alaska to you and your viewers. Love the videos, keep em coming!!
Good tip. I recently had to run my generator in single digits and was waiting for the carb to ice up. Some models allow you to adjust the air pickup to recirculate hot air coming off the head or exhaust pipe to prevent that. Most do not have that.
You are a real die hard James. I thought that you had given up on this one. I took another look at the previous two videos for this about 3 months ago. I gave some consideration to what else you could do to this machine without breaking it down or paying the full price to repair it. It did occur to me that it might make a good portable DC output machine rated at say 300V dc at 8 - 10A. Machines like this are mostly switch mode based. These SMPS ones sell at a pretty penny. This would be an old fashioned linear one. Ah Well it was a good idea.
12:13 you can restore plastics like those with a heat gun. Run it just over the surface until you see the plastic turn shinny and keep moving it like a paint gun. You can experiment first on the inside. Clean it very well with acetone or lacquer thinner first.
Nice job! We have 3 of the 6300isde with 5-6000 hrs on them. All 3 have similar issues to the one you worked on. The sad part is that they have 2 inverter modules.😮
Great video as always. Those Yamaha gensets are awsome. My son has two of them and uses them in his business and they are very reliable and great quality. Thanks for making this video!
Very nice, been wondering what happened with this one. I enjoy the show and watch often, it gives me confidence I could actually do more myself than I typically would believe. Nice to see it brought back to life. Someone will have themselves a bargain with that unit, unless you are tempted to keep it? I have the very same generator, perhaps a more recent version about 6-8 years old, but set up for Australia with 2 x 15 A 230 V outlets. I got it for half price with ~10 hours on the clock. Super nice machine. Starts first turn of the key every time and the pull start is also very easy. I keep mine inside a housing with the factory Yamaha cover. Even have the original packing box! Treat them well and they will not let you down. Resale value very high here. It's my backup to my backup (I have an off-grid battery set up) so if needed it can re-charge my battery with 2 kW being a charging sweetspot for me, or just power the home directly which it also does well and absolutely no concern about power quality. It has perhaps 25 hours only (no runtime clock on these). I get it out every so often for a run, put the battery on the trickle charger and like yours I have a battery plug set up to make for an easy external connect to the charger. I gave it an oil change the other day which reminded me about your incomplete project. These Yamahas make such a satisfying purr and that engine wind down sound is a dead giveaway of the Yamaha. Didn't happen to do a noise level test? They seem so quiet. Thanks for your channel.
I would have tested the noise. It sounds a lot louder in the video, but it’s very quiet. These in running condition usually go for $1200-$1500. $900 is the rock bottom price I have ever seen. On eBay they have broken ones for $900.
If this was 20 years old, it would date back to 2003. I left a comment on video number 2 of this generator saying that if a cap is physically damaged it is almost certainly electrically damaged. 2003 is smack dab in the bad cap era. This great affected the electronics industry. You saw premature capacitor failures very widespread. I have fixed MANY computers from the era. I was fixing them back when they weren't obsolete. I don't know if it was widespread outside of consumer electronics (or affects such large caps), but if it was, that could be the reason. It was very widespread and not a brand (of the equipment) was spared.
Mr. Condom I wished you lived closer to Texas I have a Honda that needs some work 1 leg is gone you would be the only one I would trust to fix it. I love the videos keep up the GREAT work.
@@jcondon1 He may be embarrassed about. If you would like me to reach out to this person, it might allow the inverter to be returned because the person won't have to face you in conversation. Let me know whatever I can do! I repair lots of inverters in medical equipment, and rebuild switch-mode power supplies for entertainment.
I really wished you would have de potted the board. I have one of these and it failed the day after the warranty went out here in Chile South America. We really depend on our generator since we live off grid. So now I am up a creek so to speak. Thank you kindly for the video either way as it was very informative. Jim in Chile.
Another fix, ta very much. I'm glad that our views helped out here. I do find that some channels really push merch etc which annoys me (hubnut are you listening). You just provide excellent content, don't ask for anything and these vids are magic. Thanks again Jim.
James!! Thanks for all your video's on the generators, you helped solve my problem! I'm also glad to see that when you repair an old carburetor, you actually clean the the whole unit, and once the generator is fixed you cleaned the whole generator, not many repair men do that, but I have always done it, and been laughed at for doing it! Do you think you could do 2 more videos on generators, one for installing a duel carburetor for natural gas, and gas, and do you know of any way to install a better muffler system to quiet a generator down. Again thanks James for your video's, keep up the good work!
Great video. Helping me diagnose my Westinghouse iPro4200. During my quarterly test run using my Camper AC unit, it went into overload and would not come back out. Of course Westinghouse telling me it's my fault even though it's run it before, but I digress. Thought about getting a new inverter unit but could not bear thinking about spending 180 bucks for a maybe $600 generator. On a whim I took the x3 20A GFCI outlets out of the circuit and I get a green light. No other obvious signs of a short anywhere. Can GFCIs fail without popping and cause my short? I'm going to install one at a time and see if that's what's causing the fail. Load side is in parallel, bonded neutrals are in series. UGH
Yeah James you might have gave me the motivation to finally buy one as well. Was really excited to see a finish to this repair series. I basically have the same generator with a bad control board but the replacement cost always stopped me. Board got damaged from falling off a pontoon on the road and that was almost ten years ago now. But generator has low time and was quite new then. I should just spend the money and get a new one. Thanks again and love to see extended test runs. Great video and content. Keep them coming.
Beautiful machine ideal rating very low distortion and Yamaha quality. Pretty quiet too I like how inverter generators do not drop frequency on heavy loads as the frequency is set by electronic circuitry not governer settings engine speed and loadings. That has to be worthwhile fixing even with the expensive inverter board replacement.
As a computer engineer (and owner of the same generator), I would love to know what went wrong with the original inverter board and try to fix it. Though getting through that potting material could be a biblical level lesson in patience and persistence.
I was hoping to do the same. I actually sent the original failed inverter to a subscriber who wanted to depot it. He went radio silent shortly after he received it. Guess it did not go well.
@@jcondon1 The key is not to depot the whole thing but to try to go after likely suspects like the large capacitors or the MOSFETs. That's much more doable than depotting the whole board.
Excellent video and having the expertise to test, diagnosis the problem and come up w/ a cost effective solution. Glad you have the equipment to show the THD and sine wave to confirm that this unit will be safe to run sensitive electronics. Keep up the great videos.
Modern AC inverters create a high voltage half - waveform followed by 4 Mosfets in a "H" bridge to invert the polarity of alternating half cycles to produce the normal AC output. Looks like your original inverter module just needed two replacement FETs which probably blew open circuit although getting to them through the potting compound would not have been easy. Maybe $10 ?
Hello Jim I learnt a lot from you video's thanks. Based on the cost of the inverter module you should continue to remove the potting. It looks like the positive side of the sine wave is missing based on the clipping shown on the oscilloscope. This is passably caused by a bad three phase bridge rectifier, the IGBT or Mosfet power transistor(s), or that hv cap that's damaged may be bad. Due to the high cost of this module you should consider digging deeper. It maybe nothing more than a few diodes (Arcing wires?) that need to be replaced. It appears to me (as far as I can see) that everything else in the module is working ok. By the way Very good job constructing the AVR circuit from the schematic in your other video and you apparently have little electronics knowledge impressive. Best wishes.
Thank you! I have a ef1000is with a similar problem . I will be running the test and looking for other faults that you have pointed out. (It to was given to me. )I was afraid that would be the problem. Thank you so much for showing it. Dean
Nice videos, I watched all three. Just wondering why the 15 amp breaker didn't pop with that 2500 watt load. There is a 23 amp socket next to the 15 that could have been used with the right plug. I have four of those generators, they are terrific.
There is not circuit breaker on this model. The inverter monitors for an overload exceeding 2800 watts. So technically you can pull 23 amps out of the 15 amp outlet. The inverter does not know which outlet is being used.
Something to think about, when it comes to selling this include the fact that it has a new inverter board and if people are smart they would look up the cost of that part. So, I would think with the new board you should be able to get your money back and then some, but if the generator was using it’s original board, I can see the $900 being the potential price. Have you seen Terrel Fixes All video about why he hates Hondas, it’s definitely a good watch.
I saw that. Definitely a hard repair to justify. Honda inverters are usually cheaper. I looked up the cost for a new inverter on my Honda EU6500 and think it was only $600. Twice the power and half the cost. These machine are a lot new and the inverter is the most expensive part to replace.
Great video as usual James! One question though, were you measuring THD on the output of a surge protected power strip? If so, wonder if it has any impact on the THD levels.
It should not impact THD. Those surge protected strips usually just have a few sacrificial metal oxide varistors. Normally they do nothing unless there is a voltage spike.
Which utility provides power to your house? We used to live in N.Y. about 20 years ago. I happen to see the new style N.Y. plates in your driveway. I used to work for ConEd when we lived in Westchester County. We live in Connecticut & I work for Eversource Energy as a lineman. I see a huge difference between an inverter generator & and non inverter generator. The sine wave is perfect & the voltage is on the high side but comes down with load. Also the THD is vastly better. Hence why I picked an inverter generator at my house. I talked to many of people (mostly customers) & they only know “watts”. It’s sad because they go by the big number printed on the side of the machine. When I talk about the other important issues I get the blank face. We do business with a small mom & pop business that sells kitchen appliances. They tell me after a big storm customers come looking to replace all their appliances after their generator burned up all their appliances. Not to say they look forward to big storms? They just know people buy the cheapest generator & burn up $10,000 in appliances. Makes perfect scence! 🤨
James, from your videos I know that a gas generators differs for a gasoline one mostly with pressure reducer and carburettor, but what about diesel? Can you give us a video on how to diagnose and repair a diesel generator? I found no good video on youtube neither in English nor in Russian.
Thanks god is not a 4th video it felt like a series where you want to find out what would happen on the next episode Im glad I finished. Bc im in the same situation 🤦🏻♂️. On a AIms gen6600w 120/240v electric starter inverter. But like u said the problem is I can’t find any parts for sale. N inerd the dame part you replace.
I have one of these and I’m about to throw it out. POS 15amp plugs won’t even work to run my Fridge. It ran my entire trailer yesterday so idk why it won’t work on the smaller plugs.
After the loss of a few aircraft in the '80s due to wire chafing the USAF launched a service-wide anti-chafing training program. I attended some of that training. 😉

Can't believe you found that yellow replacement!
So awesome.
That's great you were able to get a new inverter module, this generator lives again, nice work James!
Well done sir for putting some (the) YT money back into this generator, it’s a shame to see so many scrapped.
I like shiny stuff Jim, it's easy to shine up the other black parts.
I use Aerospace 303, or the automotive protectant called Back to Black.
I love the fact it did not end up in the land fill. That sir is my favorite part of all your videos - and you recycle parts when you can, ALSO a massive plus. Love ALL your videos!

I just watched all three videos in this series and was pleased that you finally got it running. Congratulations on your persistence James!
That is the cleanest sine wave I've ever seen from a genset.
Best sine wave ever. The original failure looked like a diode clipping. Totally impressed with Yamaha. Looked like a sine wave from a power company.
Well that was nothing short of war !
Inverters give nice clean power. However if you can get by without it and are working on a tight budget I'd advise staying away from them, especially if it's old. Newer models have probably come on somewhat..

@@jcondon1 At least sometimes. You rarely get more than you pay for
I use these videos to help me sleep - it’s a complement. Thank you
I was kind of hoping that Yamaha might have come to the party and supplied you with the part but ah well. Great video. Don't stop what you're doing ❤
so glad this channel has grown as much so you can finish projects. congrats on 100K subscribers! cheers
Thanks
Very nice, been wondering what happened with this one. I enjoy the show and watch often, it gives me confidence I could actually do more myself than I typically would believe. Nice to see it brought back to life. Someone will have themselves a bargain with that unit, unless you are tempted to keep it?
I have the very same generator, perhaps a more recent version about 6-8 years old, but set up for Australia with 2 x 15 A 230 V outlets. I got it for half price with ~10 hours on the clock. Super nice machine. Starts first turn of the key every time and the pull start is also very easy. I keep mine inside a housing with the factory Yamaha cover. Even have the original packing box! Treat them well and they will not let you down. Resale value very high here.
It's my backup to my backup (I have an off-grid battery set up) so if needed it can re-charge my battery with 2 kW being a charging sweetspot for me, or just power the home directly which it also does well and absolutely no concern about power quality. It has perhaps 25 hours only (no runtime clock on these). I get it out every so often for a run, put the battery on the trickle charger and like yours I have a battery plug set up to make for an easy external connect to the charger. I gave it an oil change the other day which reminded me about your incomplete project.
These Yamahas make such a satisfying purr and that engine wind down sound is a dead giveaway of the Yamaha. Didn't happen to do a noise level test? They seem so quiet.
Thanks for your channel.
I would have tested the noise. It sounds a lot louder in the video, but it’s very quiet. These in running condition usually go for $1200-$1500. $900 is the rock bottom price I have ever seen. On eBay they have broken ones for $900.
Vibration sensing hour meters are quite cheap.
I feel like I gave birth here! What a long journey. Thanks so much. 🤔❤️👍✌️
If this was 20 years old, it would date back to 2003. I left a comment on video number 2 of this generator saying that if a cap is physically damaged it is almost certainly electrically damaged. 2003 is smack dab in the bad cap era. This great affected the electronics industry. You saw premature capacitor failures very widespread. I have fixed MANY computers from the era. I was fixing them back when they weren't obsolete.
I don't know if it was widespread outside of consumer electronics (or affects such large caps), but if it was, that could be the reason. It was very widespread and not a brand (of the equipment) was spared.
Thank you for the explanation ,I will have to read it a couple of times to let it sink in but thank you .
Good informative video Jim That sine wave was was close to perfect that would have been a great generator for a ham operator
Mr. Condom I wished you lived closer to Texas I have a Honda that needs some work 1 leg is gone you would be the only one I would trust to fix it. I love the videos keep up the GREAT work.
Thanks!
Thanks Geoff!
Nice to see persistence has it's rewards.
I sure would love to de-encapsulate, diagnose, and repair that old inverter board if it's available.
Unfortunately not available. I sent it to another subscriber who wanted to do the same. He went radio silent shortly after and it was not returned :(
@@jcondon1 He may be embarrassed about. If you would like me to reach out to this person, it might allow the inverter to be returned because the person won't have to face you in conversation. Let me know whatever I can do! I repair lots of inverters in medical equipment, and rebuild switch-mode power supplies for entertainment.
I really wished you would have de potted the board.
I have one of these and it failed the day after the warranty went out here in Chile South America.
We really depend on our generator since we live off grid. So now I am up a creek so to speak.
Thank you kindly for the video either way as it was very informative. Jim in Chile.
thank you James. brought another one back to life.
Another fix, ta very much. I'm glad that our views helped out here. I do find that some channels really push merch etc which annoys me (hubnut are you listening). You just provide excellent content, don't ask for anything and these vids are magic. Thanks again Jim.
James!! Thanks for all your video's on the generators, you helped solve my problem! I'm also glad to see that when you repair an old carburetor, you actually clean the the whole unit, and once the generator is fixed you cleaned the whole generator, not many repair men do that, but I have always done it, and been laughed at for doing it! Do you think you could do 2 more videos on generators, one for installing a duel carburetor for natural gas, and gas, and do you know of any way to install a better muffler system to quiet a generator down. Again thanks James for your video's, keep up the good work!
Thank you for sharing your video tutorials. Greetings from one of your supporters from Canada
You’re welcome 🙏
very nice video James. great repair.
That part is $1200 dollar's ouch that is expensive glad you got it to work on this machine
Yamaha parts are not cheap.
@@jcondon1 that is the truth about that matter young man 👍😎
Great video. Helping me diagnose my Westinghouse iPro4200. During my quarterly test run using my Camper AC unit, it went into overload and would not come back out. Of course Westinghouse telling me it's my fault even though it's run it before, but I digress. Thought about getting a new inverter unit but could not bear thinking about spending 180 bucks for a maybe $600 generator. On a whim I took the x3 20A GFCI outlets out of the circuit and I get a green light. No other obvious signs of a short anywhere. Can GFCIs fail without popping and cause my short? I'm going to install one at a time and see if that's what's causing the fail. Load side is in parallel, bonded neutrals are in series. UGH
Yeah James you might have gave me the motivation to finally buy one as well. Was really excited to see a finish to this repair series. I basically have the same generator with a bad control board but the replacement cost always stopped me. Board got damaged from falling off a pontoon on the road and that was almost ten years ago now. But generator has low time and was quite new then. I should just spend the money and get a new one. Thanks again and love to see extended test runs. Great video and content. Keep them coming.
Beautiful machine ideal rating very low distortion and Yamaha quality. Pretty quiet too I like how inverter generators do not drop frequency on heavy loads as the frequency is set by electronic circuitry not governer settings engine speed and loadings. That has to be worthwhile fixing even with the expensive inverter board replacement.
As a computer engineer (and owner of the same generator), I would love to know what went wrong with the original inverter board and try to fix it. Though getting through that potting material could be a biblical level lesson in patience and persistence.
I was hoping to do the same. I actually sent the original failed inverter to a subscriber who wanted to depot it. He went radio silent shortly after he received it. Guess it did not go well.
Darn! Maybe he will surprise us all with a reply here, even if it's to let us know that he got stuck at depotting.
@@jcondon1 The key is not to depot the whole thing but to try to go after likely suspects like the large capacitors or the MOSFETs. That's much more doable than depotting the whole board.
Nice.. Glad you were able to get the part to fix it !
A year in the making and turned out fine 🙂 😍 😌
Nice knowing all this stuff instead heading for the landfill. Really sucks Yamaha charge so much for a spare inverter!
Thank you James. Looks to be a very nice generator for a customer. The Hertz and voltage were steady and great THD values.
Great Job, Jim! Thanks for perservering.
A very nice series of videos, I went back and watched all.
Excellent video and having the expertise to test, diagnosis the problem and come up w/ a cost effective solution. Glad you have the equipment to show the THD and sine wave to confirm that this unit will be safe to run sensitive electronics. Keep up the great videos.
Modern AC inverters create a high voltage half - waveform followed by 4 Mosfets in a "H" bridge to invert the polarity of alternating half cycles to produce the normal AC output. Looks like your original inverter module just needed two replacement FETs which probably blew open circuit although getting to them through the potting compound would not have been easy. Maybe $10 ?
That was the worst parts about buying a new one was knowing it was a cheap repair most likely if only the potting was not there.
Great job. I have a Yamaha , but issue is servo not bringing engine up to speed
That is a sweet little generator , wish I had one!
A great way of bringing some thing back to us again with the money from TH-cam
Again James another good save, well done mate, very well done!
Hello Jim I learnt a lot from you video's thanks. Based on the cost of the inverter module you should continue to remove the potting. It looks like the positive side of the sine wave is missing based on the clipping shown on the oscilloscope. This is passably caused by a bad three phase bridge rectifier, the IGBT or Mosfet power transistor(s), or that hv cap that's damaged may be bad. Due to the high cost of this module you should consider digging deeper. It maybe nothing more than a few diodes (Arcing wires?) that need to be replaced. It appears to me (as far as I can see) that everything else in the module is working ok. By the way Very good job constructing the AVR circuit from the schematic in your other video and you apparently have little electronics knowledge impressive. Best wishes.
a new pefect sine wave control board....! A high sales price for this is 100% justified since it delivers clean/distortion free power!
Sounds great. Quiet as well.
Thank you for not making me cringe and using flush cutters to cut the tyraps. 😊
Thank you! I have a ef1000is with a similar problem . I will be running the test and looking for other faults that you have pointed out. (It to was given to me. )I was afraid that would be the problem. Thank you so much for showing it. Dean
Nice videos, I watched all three. Just wondering why the 15 amp breaker didn't pop with that 2500 watt load. There is a 23 amp socket next to the 15 that could have been used with the right plug. I have four of those generators, they are terrific.
There is not circuit breaker on this model. The inverter monitors for an overload exceeding 2800 watts. So technically you can pull 23 amps out of the 15 amp outlet. The inverter does not know which outlet is being used.
Your perseverance is commendable.
James you are a genius love your videos
I would have like to see what that oil looked like on the second oil change!
Quick shipping, beautiful unit, easy to use
Something to think about, when it comes to selling this include the fact that it has a new inverter board and if people are smart they would look up the cost of that part.
So, I would think with the new board you should be able to get your money back and then some, but if the generator was using it’s original board, I can see the $900 being the potential price.
Have you seen Terrel Fixes All video about why he hates Hondas, it’s definitely a good watch.
I saw that. Definitely a hard repair to justify. Honda inverters are usually cheaper. I looked up the cost for a new inverter on my Honda EU6500 and think it was only $600. Twice the power and half the cost. These machine are a lot new and the inverter is the most expensive part to replace.
@@jcondon1 Are they typically all potted like that?
Hi James nice generator well worth saving thanks for sharing mate
That is a nice generator, glad you saved it. Thanks for the great videos.
Great fix Jim. Most people would send it to the landfill. I like the Yamaha better than the Honda's. Thanks
That is where I found it
Nice fix Jim!
A satisfying success story! Awesome!
Great video as usual James! One question though, were you measuring THD on the output of a surge protected power strip? If so, wonder if it has any impact on the THD levels.
It should not impact THD. Those surge protected strips usually just have a few sacrificial metal oxide varistors. Normally they do nothing unless there is a voltage spike.
Congrats on 100k subs!!!
Thanks
Could you explain what we are seeing on the sign wave?
Which utility provides power to your house? We used to live in N.Y. about 20 years ago. I happen to see the new style N.Y. plates in your driveway. I used to work for ConEd when we lived in Westchester County. We live in Connecticut & I work for Eversource Energy as a lineman.
I see a huge difference between an inverter generator & and non inverter generator. The sine wave is perfect & the voltage is on the high side but comes down with load. Also the THD is vastly better. Hence why I picked an inverter generator at my house. I talked to many of people (mostly customers) & they only know “watts”. It’s sad because they go by the big number printed on the side of the machine. When I talk about the other important issues I get the blank face.
We do business with a small mom & pop business that sells kitchen appliances. They tell me after a big storm customers come looking to replace all their appliances after their generator burned up all their appliances. Not to say they look forward to big storms? They just know people buy the cheapest generator & burn up $10,000 in appliances. Makes perfect scence! 🤨
James, from your videos I know that a gas generators differs for a gasoline one mostly with pressure reducer and carburettor, but what about diesel? Can you give us a video on how to diagnose and repair a diesel generator? I found no good video on youtube neither in English nor in Russian.
An investment well worth the money and time. Good money going after a great machine. 👍
Nice gen set and sine wave. For some reason, it reminds me of a VW van, LOL.
Thanks god is not a 4th video it felt like a series where you want to find out what would happen on the next episode Im glad I finished. Bc im in the same situation 🤦🏻♂️. On a AIms gen6600w 120/240v electric starter inverter. But like u said the problem is I can’t find any parts for sale. N inerd the dame part you replace.
I have one of these and I’m about to throw it out. POS 15amp plugs won’t even work to run my Fridge. It ran my entire trailer yesterday so idk why it won’t work on the smaller plugs.
Hi James, if you ever need parts voor a yamaha ef1000 or a Honda ex1000 I still have a hole lot of parts.
After the loss of a few aircraft in the '80s due to wire chafing the USAF launched a service-wide anti-chafing training program. I attended some of that training. 😉
