Remove back shroud and check
fuses.
Verify output voltage on charger,
it should be 26 to 30 volts, dc,
connected to batteries, and
plugged into 115vac.
Load test the batteries
Locate Pin 2 on Molex connector
at motor controller. Trace wiring
to contactor and verify
connection.
While attempting to go forward,
tap on the contactor with a
screwdriver handle. If the unit
moves forward, then the
contactor may need replaced, or
plungers lubed with a light oil.
Remove both wires from each
side of the contactor, and check
with ohm meter; resistance
should be approximately 38
ohms. If it's open or zero, the
contactor should be replaced.
