I have a Generac/B&S Power Boss 5500 Generator. I needed to use it this past week and when I cranked it up it output over 300 volts. I've researched on the internet and have found only the users manual. No repair information. The owners manual shows an exploded view but I find no reference to a voltage regulator in the view. I found that newer Generacs have an AVR (automatic Voltage Regulator) that can be changed to remedy the over voltage situation, but nothing for this model.

It is model 01642 Rev 1.

If anyone has any knowledge about this model, I would appreciate a direction I might follow that might renew this generator to full function.

Thanks in advance.

It looks to me like the first two items on that page should help a little.
