POSSIBLE CAUSES
CORRECTIVE ACTION
Note: Charge indicator light
would normally be on during
a charge inhibit but could be
malfunctioning.
Note: Brake lights would
most likely be on without
depressing brake pedal if the
brake switch was at fault.
Brake switch fault.
Controller fault.
Test brake switch. Replace if
necessary.
Check voltage at controller motor
terminals with key set to high while
depressing accelerator. Voltage should
rise as accelerator is depressed. If no
voltage and all necessary controller
inputs have checked ok, then replace
controller.
Nothing works.
Note: If fuse is blown,
be sure to learn why
before trying to operate
vehicle.
Battery fault.
Fuse blown.
Faulty ignition switch wiring
circuit.
Check voltage at battery terminals on
controller. Should read approximately
48VDC. If no voltage, could be a blown
fuse, bad battery connection, bad
master switch, or faulty battery
interconnection cable.
Open master power switch and check
continuity through fuse.
Unplug jumper harness from main
harness and check voltage to switch by
placing negative voltmeter lead on pin 2
(black wire) of main harness plug and
read voltage to all other pins. Should
read about 48V to each pin.
If voltage is correct, check switch and
jumper harness continuity. If switch and
jumper harness continuity is not correct,
check jumper harness by itself. If
jumper harness resistance checks
good, check switch continuity.
If voltage is not present at switch
connector, check continuity from main
harness side of jumper harness
connection to pins on large twist lock
controller connector as shown below.
Large Twist
