I am stumped! Tractor was running fine and mowing then just quit. No Lights, no ignition, no start, and no clutch power. Battery both + and - connections good. Replaced ignition switch and circuit breaker reconnected battery and there was one click but nothing else. Disconnected battery to check for shorts with continuity tester and found continuity to ground on all three voltage regulator terminals on the Onan engine. Something tells me this is not right. Any help would be appreciated.
