Re: honda es6500 generator overvoltage

If you are mechanically handy, remove the cover on the generator end. Inside on lower left is the automatic voltage regulator (AVR) which is a curved box-looking thing on K2 models, diamond shaped box on earlier models. An output overvoltage is caused by the AVR not throttling the generator field voltage properly. Look toward the top and you will see the brushes in their holder. With the generator running at normal speed (3600-3750rpm), you should be able to measure around 25Vdc with a voltmeter at the connector to the brushes. Any more (and I bet there is), and the AVR is bad. I had the same problem and I ended up buying a replacement AVR from Plano Power Equipment for just under $300.00. Do an internet search to find them.
