Check if all the connections between the motor, the battery, and the con-
troller are in good condition.
Use the following cleaning procedure for routine maintenance:
1. Turn the power key to OFF position.
2. Remove power by disconnecting the battery.
3. Discharge the capacitors in the controller by connecting a load (such as a
contactor coil or a horn) across the controller’s B+ and B- terminals.
4. Remove any dirt or corrosion from the connector areas. The controller
should be wiped clean with moist rag. Dry it before reconnecting the bat-
tery. The controller should not be subjected to pressured water flow from
either a standard hose or a power washer.
5. Make sure the connections are tight, but do not over-tighten them.
NOTE:
All above checks should be performed with the power off. Above checks
shall be carried out once every 3 months; after the power is turned off, the
wave-filter capacitor in the controller unit should continue discharging for a few
minutes more; don’t wash the electrical parts with water. You can remove dust
with a brush or high–pressure air.
