2002 GEM Dead Overnight

I have a 2002 GEM, display came on for a few second and goes off, key switch is only showing 13.5 volts. Solenoid is showing 75.1 volts. Lights, turn signals, horn, wipers and lights work. No display so no error code shows.

Sounds like the batteries are charged and the 12V DC-DC converter is working. So, did you check the wiring from the display back to the controller? Maybe throw the main disconnect and check the connections on the controller too.

Need B+ on controller pin 2 for display.
