TROUBLESHOOTING FOR BUILT-IN CHARGER
5. Disconnect the charger from the AC source.
Locate the charger harness connectors where the charger harness is connected to the vehicle’s control
harness. There will be two 10 gauge and two 14 gauge wires.
Slide the insulators off the connectors on the two 10 gauge wires and perform the following tests:
6. Test the voltage from the red wire to the main battery negative. This voltage should
be equal to the battery voltage. If the voltage is less than the battery voltage, then
this wire is broken or has a bad connection.
Stop here and repair the problem.
7. Test the voltage from the red 10 gauge wire (+) to the other 10 gauge wire (white
or black depending on model). This voltage should be equal to the battery voltage.
If the voltage is less than the battery voltage, then the white (or black) wire is
broken or has a bad connection.
Stop here and repair the problem.
Slide the insulators back onto the connectors on the two 10 gauge wires.
Slide the insulators off the connectors on the two 14 gauge wires.
Re-Connect the charger to the AC source.
8. Test the voltage across the two 14 gauge wires. This voltage should be the same
as the voltage at the AC receptacle (rated voltage of the charger). If the voltage is
less than the rated AC voltage of the charger then the 14 gauge white or black
wire(s) is broken or has a bad connection between the charger connectors and
the AC plug.
Stop here and repair the problem.
1. Make sure the key-switch is in the “OFF” position, then remove the
key.
2. Place the forward-reverse switch in the center “OFF” position.
3. Set the park brake.
4. Place blocks under the front wheels to prevent vehicle movement.
High Voltage. Do not touch the 14-gauge wires and make sure these
two wires do not come into electrical contact with any other object.
Failure to do so may result in serious bodily injury.
Make sure that these two wires do not come into electrical contact
with any other object.
