2001 Challenger with twin Rotax 717s.
Curious intermittent problem, must be electrical. I read posts on MPEM diagnosis and cleaned the connectors, checked all fuses, still happening.
Sometimes the MPEM doesn't beep when I connect the DESS key, but I hear a soft click. Engines crank normally, start, and run well, but none of the gauges or accessories work, except strangely the fuel gauge.
Must be an intermittent short somewhere in power supply. Any ideas where to look?
