Mep003 rapid engage and disengage of starter/ spontaneous producing AC

[armyrino]

Good evening everyone. So I am a little stumped. Which doesn't happen easily. Lol. So I have a mep003 . Unit is very clean with only 24hrs run time. So I picked up a sweet trailer power plant with two mep 003 units. This unit had a problem with the injection pump. Which I fixed. Unit fired up and ran great plus produced voltage as it should. Ran unit a couple of times and even load tested. Everything ran great. Covered trailer up and let set for a month. Next time I went to star it the starter would engage and disengage rapidly. Once it would start then it would not produce and voltage but ran great.

Start with the starter lockout to make sure its adjusted correctly. That could be causing your starter issue. After the unit is up and running try to hold the master switch to start so it will excite the field.

Never had to adjust the staryer lock out. How do you gobabouy adjusting the lockout.
When it is running I have held the starter switch in the start position to flash the field. It doesnt do anything. You can see the dash light dim when I do and the dc voltage gage dips down a little almost like its applying a load but nothing happens. But as I said it will sometimes work just fine and then it wont. Unfortunately it doesnt qork more than work.

I would open the -12 TM and find the procedure. Its not hard. Starts on PDF reader page 144. Might not be a bad idea to read up on first.
