                  Remove 2 jumper wires from R606 locations and replace 2.2 ohm, 20W Cement
                  Resistor.

Note:             1. The circuit board has large hole for mounting this cement resistor.
                  Therefore, please bend resistor legs at foil pattern side to avoid cold solder joint.

                  2. This circuit upgrade will reduce AC spark at plug in.

                                                  20W RESISTOR




                                             REMOVE JUMPER WIRE

                                             ADD 2.2 OHM, 20W CEMENT RESISTOR

                                             BEND RESISTOR LEGS TO AVOID
