A subscriber dropped off his generator which was in storage for 5+ years. He fixed the fuel problems only to find out that the generator was only generating 35 volts! After a little work, was able to fix the issue and it makes 120 volts again.
Generator Model# 030471-01

There are those who swap parts until it works. Mr Condon is a forensic pathologist when it comes to repairing generators and engines. Not only does he identify what failed, but why it failed and he explains it well. The "why it failed" keeps generators coming back for a repair of the same problem. I hope I don't have to but if my generator fails, I might just be able to repair it now.

We have used the kzfaq.infoUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y for probably 30 hours with our camper and it’s been great! The noise level is really only noticeable when running the AC and other appliances like the microwave, hair dryer, or coffee pot. It’s not huge like other ones and it has wheels so even at 90lbs, I can move it!

I have that very generator. I ran it pretty regularly for 1/2 hour a week as recommended for more than two years and just out of warranty, @90h it developed a stuck intake valve and bent a pushrod. No kidding, it was maybe the second time I ever pulled the cord to start it -- normally used the starter. I took the head off today, broke the plastic lever the remote choke cable attaches to DOH! I freed up the stuck valve, cleaned up the head -- there is evidence of rust in the intake tract and blow by on the bottom of the head -- two head bolts were very snug, two others were less so. TONS of carbon and sticky stuff around the exhaust valve. Tommorrow is reassembly day. Wish me luck! Excellent video -- helped this guy! Oh yeah, my engine does not look exactly like this, the markings on the valve cover are different, and it is a different shape. Edit - it is running in the yard, it now has 91h on it! Only one part left over. :( groan.

Adjusting the potentiometer on the AVR was the takeaway on this vid for me. So simple. So obvious. And I never considered it. Question about that arm setting and adjustment ‘room’ on the throttle adjustment: what if you moved it to the fourth hole? Wouldn’t it give you more threads on that bolt? Would it make sense to put a drop of a thread locker on that throttle bolt to keep it from moving in or out? Thanks for your videos. Familiarization of all the different engines is really eye opening. And comforting.

Excellent video! It's always a treat to see a true mechanic at work. Full knowledge of the machine and testing/ investigating instead of guessing/part changing. After several months on loan I got my Powermate generator with Honda motor back. Upon starting and checking it over I found it was only supplying 103v. After watching this video I dove right in and after checking resistance at all the locations mentioned, inspection of brushes and cleaning the slip rings, it moved to 106v. Upon inspecting the AVR made by GTDK I found an adjustment screw on the front. After two adjustments to complete 3 full turns, it now supplies 119.8v. This style AVR doesn't require removal of the AVR to adjust it. Thanks, I learned a lot...

I am quite proficient at electrics and electronics in general but have always shied away from the power end of gensets. After watching your trouble shooting process over and over I am getting much more comfortable as I do with small engines going through “the Mustie1” process. Really great stuff from you. When I can say out loud what I think you will try next then I am getting there!! Thanks for great videos of real time trouble shooting.

Nice job of explaining everything you had to do on this generator. I used to work in a factory with a lot of DC motors and one thing we did to clean up commutators was to put fine emery cloth under the brushes and turn the motor over. I'm not sure if there is room to do it on these small generator slip rings, but you might want to try it sometime if you haven't already.

Nice job on getting all the setting correct. On the cleanup, you use water and a green pad. Water may induce future rusting. I suggest WD and fine steel wool as an alternate.

love the video.. stumbled upon this for adjustment of governor and frequency. Happen to have the exact same generator.. Use it for music festivals and dance events running a very large PA system and nightclub lighting etc on stages for several hundred people.. Added a 50 amp SPA breaker panel on the side, new #6 wiring to the inside and a Range plug on it. Over 12 years of use and almost 1200 hours on it.. This generator is pretty much bullet proof! Still runs like a champ with minimal work (mainly just minor engine work) think its time to check the brushes and clean the slip rings.. Thanks!

If you want a trouble free generator, then Honda is the way to go. With a little care, it will last. Most others are similar. As long as it has an oil sensor and an AVR then it is a good generator. The other thing to consider is parts support. Most Chinese engines are not branded and difficult to find parts for. Vendors like Ryobi, Briggs and Generac use Chinese engines and they also sell the engine parts. A lot of others do not. Also like any generator that has a name brand engine on it like Honda, Yamaha, Subaru and Briggs.

James, I own one of these as our main backup generator, and cannot tell you how much I just learned from watching this! I have tried to watch as many of your videos as possible and will continue, but this one hit real close to home! I'm assuming that AVR = Automatic Voltage Regulator? When I first got this unit, I was reluctant to use it to power up our new furnace with all of its electronics during power failures because I was unsure of how clean the power actually was. I read that only inverter generators (which this is not) would be acceptable. I used a scope meter on it while running a hair dryer to see what it looked like and was surprised to see a decent sine wave output! Eventually, I had to pucker up my butt and try it! LOL No issues! I did experience a failure of the fuel solenoid back when it was still under warranty and they replaced the whole carburetor. I have since only had to replace the battery. I try to exercise it every month or two. I noticed that you check the oil level without screwing in the dipstick? Checked the manual and they agree! Great video!

I had the carburetor all apart, looked very good but did a clean up and blew everything out while I was in there. Pretty obvious that someone has had it apart, lots of weird stuff, including the start/stop switch installed upside down? I have it apart to check the valve clearance and then going to see if I can sort it out. Other than the surging it seems to start and run well but voltage is a bit low, 112, 113 on both sides.

Great video as usual! My opinion (or guess) on why the original AVR failed is that the bad connections from the brushes to the slip rings caused a lot of sparking and make/break as it was running. The electrical noise produced as a result probably made the voltage spike from the winding that was powering the AVR and most likely blew a diode in the bridge rectifier buried inside the AVR. This effectively puts a short for half a cycle across the power winding for the AVR. That may explain the darkened wires. The loss of half the power to the AVR plus the resistance in the slip rings combined made it drop to 30 volts. Do you have a scope to look at the output of these generators you repair? Thank you for explaining the solenoid. If I understand properly (please correct me) the solenoid shuts off the fuel so there can't be any run on due to self ignition from carbon deposits.

49 ohms not bad for the old brushes makes sense why the brushes were bouncing all over the place because the avr was so low on voltage it was over working

You should look up a CR950. It is basically a predator 212 with a few minor changes

All of these portable generators need inline fuel filters installed bout $5:00 and a bit of fuel line to hook up. The pilot jets holes are very small and it takes one fuel station to ruin your evening. Have the same gen and if worked awesome till one fill of fuel. Had to clean carb twice,.and put filter on. fine brass grindings from pump vanes in bowl. Cheers good work James!

Well because they basically only run full speed the jet hole isn't that small it's pretty big , at least compared to a more elaborate engine with idle Jets to plug up. And you typically remove it directly from the bottom of the carburetor bowl so it's real easy too access and clean. A fuel filter is not a bad idea but it is mass that will shake around on a flimsy plastic fuel line. Bigger problem for carburetor pluggage comes from fuel turning to varnish. If you're not going to run your generator often stabilize your fuel, running the bowl dry then draining it before storage is a good idea

As soon as I saw an electrolytic cap on the AVR - that would be the 1st thing I would change in an older unit. Cheap as chips to replace.

I am a fan of compressed air, my air compressor is my go to, for cleaning and dusting.

Be extremely careful with compressed air. Dust in a generator does not usually kill it but if you blow the wingdings and not clean all the chunks completely it's a recipe for disaster. Just from experience.

Picked up a champion 7500 today and it only makes 75-85 volts. It's enough to make my angle grinder turn at half power. It has a handy built in hz and voltage meter all in one with the hour meter

This may be a crazy request but, I like the way you use the Kill A Watt meter to check the output of the generators you work on. In one of your videos would you mind showing what functions you use when you test them? I am new to maintaining my generator and I've learned lot watching your videos so thanks much...

I also use a cheap kilowatt meter knock off to check the frequency and voltage of the generator it's a easy way to do it. Much easier than using a multimeter. Especially when you're trying to make adjustments too adjust the voltage or frequency. Recently I discovered a problem using it. I discovered my voltage was dropping to 90 volts while the generator was under 2200 w load but the gauge on my generator still showed 120 V. The generator output was 120 volts when there was no load on it. With a 1000w partial load it dropped to 110 volts. Turns out the gauge was wired back on the generator head at the same place the wires to the distribution panel took off from so the problem was in the panel. I'll make a long story short by saying it was a switch that switched between 120 and 240 volts. There was a bad contact internal to switch causing resistance. I ordered another new 4pdt 250v 15a switch from amazon for $8.....problem fixed. In the past it also identified low frequency where the governor speed control had gotten messed up a little bit during transportation by something hitting it and bending the soft aluminum parts. The generator was only running 52 hz. You can get a knock-off kilowatt meter for about 15 or 20 bucks on Amazon and it comes in very useful for evaluating generator

I have watched several of your videos. I have found them to be entertaining and educational. I have a few questions about this video. Why did you not clean the slip rings and generator earlier in your troubleshooting process. You clean the units at the end of your troubleshooting process. Why not earlier?

Well done. Good detective work on the surging governor / spring location. Liked and Subscribed. Question: does it hurt anything to run the generator without a load? I like to start mine at least once a month.
@jcondon1
@jcondon1 2 жыл бұрын
It does not hurt it in the short term, but... a load will increase the heat and help burn off carbon deposits. You are doing better then most running is monthly.
