Checked the windings of the generator and it appears that I have a short between two of them, the ones terminated via (J1) pins 2, 5, 8 and 12 are shorted... Not good, will be difficult to work on, probably best to look for a new generator head, so if anybody is parting out a MEP018, let me know.

Well, I installed the control box and fired up the engine and with a known good wiring it does the same thing as before, bog down the engine when the field flash is engaged...guess the damage was already done. Next I'll be checking the generator windings for shorts and continuity... Taking a...

In a separate thread I show how one of the cylinders was replaced on the 4A084 engine and it now starts...

Thanks for taking time to respond! Alright, so I rang out the selector switch according to fig 7-4 (TM 5-6115-275-14). On the chart for 120/240V 1 Ph position, only 3 out of 11 settings were correct! Spent all day yesterday removing the switch and proceeded to hardwire the settings using...
