Thought I had given up on military generators, but I know own another. Starts easily with pull rope and runs great. On all single phase voltage settings, however, it puts out a little over 41 volts between L1 and L2 lugs. I have a reman generator head for this unit, but I’m hoping the solution...

Does someone sell the bell housing and shaft adapter to put an MEP 016 head onto a Yanmar L70?

I’ve given up trying to fix either of my MEP 831a generators. One of them has a good Yanmar L70. I’ve purchased an MEP 016 head, but I need the appropriate bell housing. Anybody have one? I would buy it or swap 831a parts. I have one of Kurt’s solid state speed controllers for an 831a and many...

Thanks so much for the work around. Machine is running smoothly and rock steady under load. It is a joy to watch the state of charge on my monitor. This is the same motor as machine we've used for four years, but it's never run this smoothly. I can tell by the sound that it's running at a lower...

This is a pinch. I need to charge my batteries. I also want to fix it properly. This engine does not have a pull start rope.

Spring is in proper position top and bottom. After I checked, I closed the gap to a little under 1/4". Now it shuts down with switch, at least with cold engine. Engine speed still cycles constantly. No idea how it may run under load with engine warm. I would love to proceed with getting load to...

The gap is set to 5/16". The machine does not shut off with the switch. Often it will turn off if I turn it to off then immediately cycle to run and back to off. Sometimes I have to open the case and kill it with the compression release. That gap is hard to adjust because the machine does not...

I checked again in about an hour. Found one of the relay hold down clips loose and apparently shorted. Fixed that. Machine ran much better. Still some fluctuation, but not much. Readings still 223 v. Ran it for over an hour with no problem. It sometimes does not turn off with switch.

When I did not find numbered terminals on the governor control module, I consulted the manual. Read there that A/B, B/C and C/A should all read 178 vac =/- 2 v. I checked those. This is your module. A/B reads 223 v. B/C reads 223 v. C/A reads 221 v. The machine is not holding a steady speed. It...

Will do. Thanks.

Gonna try this again. Here are the readings I got and posted on Friday. They may have gotten lost in the shuffle. K12-12 0v K12-4 0v K15-12 0v K15-8 0v S7-8 24.3v S5-5 24.3v S5-6 0v S5-4 24.5v S5-1 24.5v S5-2 24.5v Hope this is what you need. Thanks again for your help.

Typo on S5-4 and S5-1. They were 24.5v.

I had negative probe clamped to battery negative. I will retest in the morning with probe affixed elsewhere. Thanks again for your help.

I greatly appreciate your help. Took time and the strongest glasses I could find to make out numbers on the relay sockets. Reaching K15-12 with the probe was challenging. The small LED inside K12 came on while S5 is in On position. It went off after engine started. K12-12. 13.35v K12-4...

I have a good Fluke meter, but I’m not the best at troubleshooting. I have since learned that I have good voltage on top of inverter at L1-N-L2. I tested both 120 and 240 settings. I’ve been distracted today. Hope to find in manual where to test contactor even though I swapped the one from the...

I’ve been using an MEP 831a as backup for our off-grid solar system for four years. It has always given trouble, but the problems were less after I bought a governor control module from a member of this forum. His name may be Klopp. Three years ago, I bought a second machine for backup. It was...

I would appreciate any parts sources for these machines, I have two of them, and both need parts. I particularly need a Speed Load Control, SLC100. So far, Governors America Corp has not seen fit to respond to my inquiry. Maybe they will eventually. I've not found it anywhere else. I would love...

Thanks, Chris. I’m gonna drag it out of its shed in the morning so I can reach the pull rope. Assuming I get it started that way, where do I check the output you mention?

We use a pair of 831 generators as primary backup for an off grid solar home. The main unit has been down for a few months. For the past three weeks, the backup unit has been hard to start. Acted like weak batteries. Today it would not turn over. When I pulled the two batteries to clean the...
