SOME OWNERS MAY COMMENT ON THE STARTER MOTOR RUNNING CONTINUOUSLY. WHEN THE IGNITION SWITCH IS RETURNED TO THE "RUN" POSITION AFTER IT IS TURNED TO "CRANK", THE STARTER MOTOR MAY CONTINUE TO RUN. IT MAY NOT TURN OFF EVEN IF THE IGNITION SWITCH IS SET TO THE "OFF" POSITION.
CONTACT OF THE PARK/NEUTRAL POSITION SWITCH PURPLE STARTER LEAD WITH A SHARP EDGE ON THE TRANSAXLE MAY CAUSE DAMAGE TO THE PARK/NEUTRAL POSITION SWITCH STARTER LEAD.
DETERMINE IF THE PARK/NEUTRAL POSITION SWITCH IS DAMAGED AND CORRECT AS FOLLOWS:
1. DISCONNECT NEGATIVE BATTERY CABLE.

5. REPLACE THE PARK/NEUTRAL SWITCH, P/N 1994330, IF IT IS DAMAGED. DO NOT ATTEMPT TO REPAIR THE SWITCH HARNESS OR STARTER LEAD.
