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 accumulation of dirt, acid, fertilizer, 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.
2. Check for solenoid input. See NOTE and WARNING below.
NOTE NOTE
• BEFORE ATTEMPTING THE FOLLOWING TESTS, THE REAR OF THE VEHICLE MUST BE
RAISED AND SECURED ON JACKSTANDS WITH THE DRIVE WHEELS OFF THE GROUND.
WARNING
• LIFT ONLY ONE END OF A VEHICLE AT A TIME. BEFORE LIFTING, LOCK THE BRAKES AND
CHOCK THE WHEELS THAT REMAIN ON THE FLOOR. USE A SUITABLE LIFTING DEVICE
(CHAIN HOIST OR HYDRAULIC FLOOR JACK) WITH 1000 LBS. (454 KG.) MINIMUM LIFTING
CAPACITY. DO NOT USE LIFTING DEVICE TO HOLD VEHICLE IN RAISED POSITION. ALWAYS
USE APPROVED JACKSTANDS OF PROPER WEIGHT CAPACITY TO SUPPORT THE VEHICLE.
