This one took me about 5 hrs to complete. I almost feel like a machinist more then a train repair electronic guy. Though it was electrical that took about 3 hrs to work out. Another tight fight that requires and upside down off centerline placement. Again clearances are close. Thickness of a heat sink can cause it not to fit. Otherwise went in nice with plenty of clearance for wires.
The issue was wiring. Had to swap motor leads, Had to resolder all the smoke and volume wires that broke off. Then I could not get the fwd coupler to fire. Pulled this board out twice to put it in the tester thinking it wasn't working. Resoldered all the pins and wiring for the light board at the coupler connection. Had good continuity but could not get it to fire. Many of the wires were too long so I did shorted them. I finally got ****ed and direct soldered the PV and coupler wire to the coupler lead. Worked. Then I realized the PV wire was too thin. So I direct routed the PV to the coupler and used a thicker jumper wire to the Light board.
I guess the PS-32 FET isn't firing long enough or the coupler is more sensitive to wiring gauge and length. I have more than 20 PS-32 conversions under my belt and this was the first time I could not get function to work with the engine wiring. Though I did notice that all the harness were extra long on this engine.
Anyway here are the pictures and glad to have this one done. G
