1995 FORD PSOM Repair

FORD PSOM - 1995 E-350 van.

I had no odometer showing, and the transmission was shifting harshly. I followed two other youtube videos in my efforts to repair this.

I did the parts replacement and it still didn't work. So I bought another unit from ebay and compared signals with my broken unit.

I determined that an internal trace in the board between the + side of the electrolytic, the + side of the MOV, and the transistor collector (point C) was broken. I added a wire jumper on the bottom of the circuit board and the unit now powers up.
