Hi ron, Interesting problem.
The XW-AGS is a dry contact system so should be no voltage there, and since that "worked" for years, seems unlikely. Only thoughts at this point are. 1. load on genny is too high. 2. generator is connected to the Grid input and it trying to sell back. 3. any new loads or production sources added lately? 4. Its not the generator, but something outside of it thats changed. Good luck, Jay peltz power On Aug 16, 2012, at 3:30 PM, Ron @ earthRight Solar wrote: > Hi Wrenches, > > I have a client that has burned up two control boards on an Onan-Cummings 5.5 > kw propane generator.
