the resistor u are looking for is roughly under gas tank close to center lifting hook, wire numbers attached to resistor should be 90 and 51, it is important to keep the resistors movable band in or very close to the same spot, this sets your open circuit voltage for weld output, if not sure resistor is good or bad, use jumper wire and hook it on wire 90 and 51, just for test purpose only!!!
