Howdy all,
Picked up a couple MEP-831A units at OKC a couple weeks back. Have one running now, with a few issues I'm hoping someone might be able to help me with.
The intermittent short light I was getting has gone away, at least for now. Ran the unit and plugged in my shop vac to clean the truck last night and it would run fine when the fuel control was locked to high-speed. Otherwise it hunts and surges nearly constantly. From what I've seen on the other MEP-831A threads, the magnet "target" on the engine speed control is out of whack.
The latest odd issue came up today. I ran the unit again, and this time it fired right up, at a lower idle, and then when I went to shut it down- it didn't. When I moved the start-run-stop switch to "stop" the DC components shut off (pumps, fuel gauge) and the unit ran at a slightly lower speed. I flipped the switch back to "run" and the unit revved up to what sounded like normal full running speeds and resumed its hunting and surging. Is this a stuck relay situation?
Where should I start with any of these issues? I'll pull the technical manual but would like to get opinions before taking a wrench to it. I understand there are specific starting places in order to get it right.
Thanks to all. Very happy to have found steel soldiers and this forum, it's been a great help!
