hi. last summer i purchased a returned 3750watt generator from home depot. i got it for half off with no warranty due to the return. it worked great when the power went out for a few days, tgen suddenly their was no electrical output, though the engine runs great. i took a look at it and noticed where the wires come out of the alternator, they werent run through a grommet. the vibration cut through both of them. i put the wires together figuring it would work again. no dice. it still runs but with no output. what gives?
