IF you have the rotor out of it, check where the wires are soldered or crimped from the windings to the slip rings. Many of them had a bad connection at that point, especially if the rotor shows open. If it shows grounded this won't apply. If it is open these wires can be cleaned and resoldered then insulated with epoxy.Harley145 said:I need a rotor for and Onan 3600 or 4000 generator
