Wow, thanks everyone for your help. I think Bundcur is unto something. I received the schematic from AssyRequired (Thanks!) and was using it to trace out the low current 72V system through the PWB, I now know the 72v signal from the keyswitch is not getting through the timer relay to the main relay. The timer relay is signaling the key is on to the “main relay” as someone called it.
This is a 12v relay that takes the constant 72v and powers the GRY/WHT wire to the motor controller.
I know the main relay is working, I tested it out of the car with a 12V source. What I don’t understand is how it’s suppose to operate. It uses a (BLK) 12V- from the DC converter and the B- from the timer relay. I don’t see how this would ever change the state of the coil.
