Yes sir. I checked each side of the power supply fuses to cabinet ground. I was told later to check on pins in the back of the board but the readings were the same from the non running car as they were from the running car in the duplex. I never had a chance to check voltages properly while I was on site. Your idea about the safe edge might hold some water on my situation. When I first found the car and could get in it and run with car calls the safe edge would not re open the doors.
