Generator blows control board


My brother-in-law has a Coleman 8750 Watt portable generator with a 13hp Honda engine. Worked fine for a couple of years and then all of a sudden it wouldn't provide any voltage at the outlets. So he called up Coleman and they said the problem was probably a $50 control board. So he ordered one and installed it. This temporarily fixed the genset but after an hour or so the electric quit again. So it appears something is causing the control boards to go bad. Any idea what could be causing this?

Best bet would be is to call Coleman again...

Sometimes they lose their magnetics and you have to take a 12 volt battery and do what they call flash the field. Been a while.
