Mine quit starting from the dash during our first trip. The following weekend, I discovered a broken yellow wire near the genset. It is in the bundle of wires coming out of the side of the genset near the box the manual start switch is on, anyway, I spliced that wire back and the dash switch works again. Hope this helps you locate the problem.
