Question

Carl, This generator came to me after I found the owner an AVR board. They still couldn't get it to produce power after installing it. I advised them to "Flash the field". Still nothing. Brought it to me. AVR board has an obvious burn on it, but I want to know what caused it before I get another board. I work on Generac and any Briggs Power Product. I have no info on these Colemans. Need a wiring schematic so I can test the stator and rotor for problems. Generator has less than 10 hours on it.Even with bad AVR board, still produces 190 volts ac on one set of power wires. Nothing on the other set. I can't tell which wire is which. Jerry [e-mail]
