PROBLEM POSSIBLE CAUSES CORRECTIVE ACTION
Broken wire.
Controller fault.
switch.
If no voltage to horn switch, check
continuity of green switch wire to pin 38
on large controller twist lock connector
and white wire to pin 40. If open circuit,
replace or repair wire.
If horn switch has voltage and operates
properly but there is no voltage to horn,
check continuity of white horn wire to
pin 13 of large controller twist lock
connector and green wire to pin 14. If
open circuit, replace or repair wire.
If wires are good to horn switch and no
voltage present at switch or if horn
wires are good and horn switch is good
but no voltage to horn when switch
pressed, replace controller.
Battery charger does
not operate.
Note: Failure of battery
or bad battery
connection could cause
charger to be unable to
charge batteries.
Note: Batteries must be
partially discharged to
show rise in voltage or
to test red LED on
charger.
No input voltage.
Charger unplugged.
Charger output unplugged.
Blown battery pack fuse.
Charger malfunction.
Check charger input voltage.
Inside front of rear body section.
Make sure charger output is plugged
into harness.
Check fuse.
Turn on charger ad see if battery
voltage goes up. Check charger LED’s
(on top of charger). Red light indicates
charging and green light indicates fully
charged. If no lights and voltage shows
no increase, probably charger failure.
Low range. Excessive load on vehicle.
Inefficient motor.
Battery pack capacity low
Check brakes for dragging.
Check tires for low air pressure.
Is the vehicle carrying an excessive
amount of weight (load capacity is 350
lbs., includes driver and cargo).
Test motor. Refer to Section 5.
Check battery pack. Refer to Section 5.
Temperature Gauge not
working (other
instrument cluster
gauges and lights ok). Faulty temperature gauge.
Note: If gauge does not
return to the minimum
position after turning vehicle
off, then gauge is most likely
bad. The gauge test here is
Set park brake.
Pry cluster from dash. Turn ignition
switch to an on position. With cluster
plugged up, use a 100-ohm resistor to
jump across pins 9 and 12. Gauge
should rise to about the beginning of the
