Will be there today. Local for me.

FWIW, the solenoid has two functions- engages the starter to the engine flywheel, but also controls current flow to the starter motor. There is a copper disc inside the solenoid that bridges a set of contacts when the coil is magnetized and the plunger is pulled in. I have seen these weld closed...

Same here in WV. I put 1/4" screen over the side air inlets, and was going to do the same on the top. Then I looked over at that exhaust flap...

I was looking for a way to load test my MEP802A and had an idea: I happened to have an old heat pump air handler laying around. The air handler has a 15KW heating coil pack installed for aux heat. Now, 15KW is too much for the 802A, however the coil pack consists of 3 separate 5KW coils...

I got things back together and load tested for 45 minutes at 90%. There was a light haze of smoke under load, but exhaust was nice and hot. Freq dropped about 2Hz drop that I adjusted up. Electrical and engine guage readings remained steady once things warmed up. I wanted to keep debris out of...

What you do during DISASSEMBLY will determine your success when assembling an unfamiliar device. If you are working with small parts, do your work in an area where dropped items can't hide from view. (I once rebuilt a carburetor in a garage with a gravel floor - bad choice). Before I started...

Stator replacement was successful and we are now making power. All modes of operation show good on the guages and my meter agrees, with one exception. I have to disclose that I incorrectly installed a jumper between position 25 and 29 on S8. The gremlin revealed itself when I switched to...

I decided to disassemble S8 to inspect and clean its contacts. These switches are rebuildable, but its best to avoid distraction while doing so. There are several different cam and contact configurations to contend with. Hold on to your "bad" switches as they are a potential source of parts to...

They were crated, so I would have given them a pass. Fortunately it was only a flesh wound lol. My issue was the fact that there were unserv tags in the bottom of each crate. The pictures of the contents were taken at an angle that did not show the tags, though they were in plain view when you...

Well, I finally had a little time to work on the 802A. I was able to secure a pair of complete generator units from GovPlanet. I found out after the fact that both have green unservicable tags (thanks GP for not including pictures of them in the auction) Fortunately, one of the units is very...

Good advice. Will do.

Something I forgot to mention - wires #6 and #9 were reversed on TB3. Maybe the culprit? I will dig deeper and update. So far the stator is top of the shopping list. Unit is clean, has 300 hours and a reman engine, so it will probably be a good one to repair. Ray, yes, please reach out with...

I have been working on a 2002 MEP802A purchased from the GovPlanet auction. Original symptom was no generator output with the engine running. I dug into the exciter circuit, and found the crankshaft sensor was backed out of adjustment. After adjusting to spec, the generator "excites" and...

I found this site while troubleshooting my MEP-802A. I have a knack for taking on unusual "projects" and this generator is no exception! My avatar picture is my unrestored 1971 IH 1110 pickup that is as ready to work as I am. Catch you in the forums.
