ELECTRICAL SYSTEM AND TESTING
DANGER
• MOST OF THE FOLLOWING TEST PROCEDURES ARE PERFORMED WITH THE BATTERIES
CONNECTED TO THE ELECTRICAL SYSTEM.
• RAISE THE REAR END OF THE VEHICLE AND SUPPORT ON JACKSTANDS. CHOCK FRONT TIRES.
• WEAR SAFETY GLASSES WHEN PERFORMING CIRCUIT TESTS. FAILURE TO FOLLOW THESE
INSTRUCTIONS COULD RESULT IN SEVERE PERSONAL INJURY OR DEATH.
WARNING
• IF A TEST PROCEDURE REQUIRES THE BATTERIES TO BE DISCONNECTED, PLACE THE RUN/TOW SWITCH IN THE
TOW POSITION FIRST, THEN DISCONNECT THE BATTERIES.
• BEFORE ANY TESTS OR REPAIRS ARE PERFORMED, THE CAPACITORS INSIDE THE CONTROLLER MUST BE
DISCHARGED. THE CAPACITORS WILL NORMALLY SELF-DISCHARGE AFTER THE BATTERY CABLES ARE
DISCONNECTED, HOWEVER, TO ENSURE THE CAPACITORS ARE DISCHARGED PLACE THE FORWARD/REVERSE
ROCKER SWITCH IN REVERSE AND LISTEN FOR THE REVERSE BUZZER.
- IF THE REVERSE BUZZER DOES NOT SOUND, AFTER THE BATTERY CABLES ARE DISCONNECTED, THE
CAPACITORS ARE DISCHARGED.
- IF THE REVERSE BUZZER SOUNDS, TURN THE KEY SWITCH TO THE ON POSITION AND DEPRESS THE
ACCELERATOR PEDAL UNTIL THE BUZZER CAN NO LONGER BE HEARD.
