Electrical Gremlins - Where to begin?

Patience is a virtue, but sometimes not.

Look on the brightside your answer would have been - Bad Ground, dead battery, go solar, 12 volt, EMS, bad converter, soy insulation, voltage drop, self resetting breaker, 120 VAC, fuse, incompetent dealer, LED, Ready Kilowatt.

The question was ?

something we said? or didn't say?

Thank you
