To test the ground, I used direct battery voltage and the ground wire at the pump motor. The system will work under those conditions.
Seems not to have sufficient amperage in the hot lines. I do want to check the grounds but I cannot find them. Anyone know where the ground points for the system are located?
Any other ideas where or what junction X48F might be?
