About the schematic, SW inquires ....

OK, now you're talking. I have some questions.
1. Are the the coils of the contactor solenoids intended to operate at 36 - 48V?
2. Are you connecting the 12V battery ground and the 36V battery grounds together? Or is only one connected to the body (I assume atleast the 12V gnd is or you'd have to rewire the rest of the car).
3. The controller looks as if it regulates only the negative connection to the motor. If the negative side of the battery is always connected to ground (once the neg contactor is closed) and the positive is always connected to the motor (once the positive contactor is closed), then there is a risk of any short (e.g. dropping a wrench) between ground and the negative motor connections throwing the motor into full power (serious lurch).
