Test Procedure 10 - Solid State Speed Controller:
DANGER
• TURN KEY SWITCH TO OFF, PUT THE F&R SWITCH IN NEUTRAL, AND DISCONNECT THE
BATTERY CABLES AS SHOWN IN FIGURE 17-1, PAGE 17-2. FAILURE TO DO THIS MAY
CAUSE THE VEHICLE TO RUN OVER YOU, RESULTING IN SEVERE INJURY OR DEATH!
WARNING
• TO AVOID ELECTRICAL SHOCK, DISCHARGE THE CONTROLLER AS FOLLOWS:
- TURN THE KEY SWITCH TO "ON" AND PLACE THE FORWARD/REVERSE LEVER IN THE
REVERSE POSITION.
- SLOWLY DEPRESS THE ACCELERATOR PEDAL AND KEEP IT DEPRESSED UNTIL THE
REVERSE WARNING BUZZER CAN NO LONGER BE HEARD. WHEN THE BUZZER STOPS
SOUNDING THE CONTROLLER IS DISCHARGED.

NEUTRAL POSITION.
• WHEN MAKING ELECTRICAL TESTS OR REPAIRS, ALWAYS WEAR APPROVED EYE PRO-
TECTION OR SAFETY GLASSES. FOLLOW ALL PROCEDURES EXACTLY AS STATED.
1. Because the solid state speed controller is a sealed solid state unit, it requires almost no maintenance.
It is recommended, however, that the following 2 operations be done occasionally.
1.1. Make sure that the electrical connections to the controller (as well as those to the motor, batteries,
etc.) are tight. When checking the controller bus bar connections for tightness, be sure to use the
double-wrench technique to avoid stressing the bus bars and cracking the seals.
1.2. Remove from the terminal area any corrosion or accumulations of dirt, acids, fertilizers, etc. It is
especially important that the controller terminal face be free of these substances. Their presence
could lead to electrical leakage and cause faulty operation.
NOTE
• PRIOR TO ATTEMPTING THE FOLLOWING TESTS, THE REAR OF THE VEHICLE MUST BE
RAISED AND SECURED ON JACK STANDS WITH THE DRIVE WHEELS OFF THE GROUND.
WARNING
• LIFT ONLY ONE END OF UNLOADED VEHICLE AT A TIME. CHOCK THE WHEELS AND LOCK
BRAKES PRIOR TO LIFTING. USE A SUITABLE LIFTING DEVICE (CHAIN HOIST OR
HYDRAULIC FLOOR JACK), WITH 454 KILOGRAMS (1000 LBS) MINIMUM LIFTING CAPACITY.
DO NOT USE LIFTING DEVICE TO HOLD VEHICLE IN RAISED POSITION. ALWAYS USE
APPROVED JACK STANDS OF PROPER WEIGHT CAPACITY TO SUPPORT VEHICLE.
2. Check for solenoid input.
2.1 Remove No. 6 white wire from A2 motor terminal and secure it so that it will not make contact with
any live components or connections.
