Disconnect either lead of the varistor (CR7).

Part number of the varistor
Serial number of the generatorAfter the varistor has been replaced, verify that the strapping of the field winding lead is securely wound on the shaft. Also, verify that the strapping of the field winding lead is securely tied.
