I got another chance to work on the generator yesterday. At the IP rebuilder's advice, I tried adjusting the droop screw, but it still wasn't acting like it should. It would bring the engine speed back up, but when I opened the circuit breaker, it would jump up above 62 Hz. He had given me...

When I took it to the shop, I told him that it was a military MEP-006A generator, which he wrote on the ticket. He's done military stuff before so I would have thought he had what he needed to get the right specs. When I got it back he even had put a new coat of CARC on it, which I wasn't...

I have worked on this set again a couple times in the last month. I followed all the above advice and came to the conclusion that the injection pump had issues inside and needed to come out. So I did, took it to a reputable local shop and had it rebuilt. He said it had lots of crud in it and the...

I went back to the camp today to work on the 006A. First thing I did was to open the timing cover to check for fuel. It was dry, no fuel came out. So I pulled the check valve out of the top of the pump and sure enough it was completely clogged. I spent about 20 minutes with various pointy...

Thanks @Guyfang! I did your steps 1 and 2 yesterday and had good fuel flow to the injection pump inlet. I did not try to run the lift pumps with the top of the tee open, but it was bone dry there. I did not try to open the drain on the injection pump either. Is that also the timing cover? I am...

Good morning and thanks for the post! The batteries on this set are less than a year old and were charged completely over the past couple days. It is cranking faster now than I have started and ran it with before, and is still showing ~25.2 volts after multiple cranking events. So I do not...

I'm back working on the camp's generator. After I got it working for them a few years back (looks like 2019 from the earlier posts in the thread) they neglected my pleads to operate and load bank it once in a while by one means or another. It never got used until last year when the camp...

I only get down to this camp a few times a year, but a couple weeks ago in anticipation of my trip today I told the camp leader that the entire exciter module was available online and that it was my only remaining suggestion to fix the generator. Tonight I swapped out the exciter module, and...

Is this the same test in the -34 described on table 2-2 item 22? It references the K5 relay on the A5 card, and has you test at the terminals on the card rather than the pins on the relay itself. I did that test a couple weeks ago and it all checked out OK. I can go back and check the other...

When I release S2 to go back to the 'run' position, no idiot lights / warning lights come on. I have verified using the test / reset switch that all the bulbs do indeed work.

I got a chance to work on this generator after work today, but unfortunately I don't have any good news to report. I replaced the voltage regulator and it's still doing the same things it did before. When I let off the start switch, it no longer makes power. I brought the old voltage regulator...

Thank you, Guyfang! This is very helpful information for me. I thought I had read that running a generator at idle would damage something, but I didn't know what it would damage and what speed / duration would cause it. I looked at the internals of the exciter assembly yesterday and didn't see...

Ok folks, I spent some time troubleshooting this MEP-006A yesterday, and I'm still stuck and in need of guidance. It starts instantly and will generate power as long as I hold the switch in the 'start' position, but if I set the switch to 'run' all of the AC gauges go dead and the engine...

I do some volunteer work with a Christian camp near where I live, and they have asked me to assist with getting their backup generator operational. It is an MEP-006A unit, obtained through a FEMA grant. They had it installed a few years ago and the power company connected it by a manual transfer...
