ELECTRICAL SYSTEM TROUBLESHOOTING

Test Procedures

TEST PROCEDURE 16 – Reverse Buzzer

See General Warnings on page 1-2.

Disconnect the batteries and discharge the controller.

See Disconnecting the Batteries – Electric Vehicles,

Section 1, Page 1-3.

Remove the instrument panel.

See Instrument Panel Removal, Section 4, Page 4-9.

Place the Run/Tow switch in the TOW position and connect the battery cables, positive (+) cable first.

See

Connecting the Batteries – Electric Vehicles, Section 1, Page 1-4.

Place the Run/Tow switch in the RUN position.

Set a multimeter to 200 volts DC. Place the black (–) probe on battery no. 8 negative post and place the red
(+) probe on the red wire terminal end that was disconnected from the reverse buzzer. The reading should be
approximately 48 volts (full battery voltage).

5.1.

If the voltage reading is correct, proceed to step 6.

5.2.

If reading is zero volts, check red wire continuity and Run/Tow switch.

See Run/Tow Switch on page 12-15.

5.3.

If the continuity readings are not correct, repair or replace the red wire.

5.4.

If the continuity readings are correct, proceed to step 6.

Place the Forward/Reverse switch in REVERSE. Using a multimeter set to 200 volts DC, place the black (–)
probe on the orange/white wire terminal end (that was disconnected from the reverse buzzer) and place the red
(+) probe on battery no. 1 positive post. The reading should be approximately 48 volts (full battery voltage).

6.1.

If the voltage reading is correct, replace the reverse buzzer.

6.2.

If reading is zero volts, check orange/white wire continuity and connection at Pin 19 in 24-Pin connector.

6.3.

If there is no continuity in the orange/white wire, or the Pin 19 terminal in the 24-Pin connector is not

properly seated, repair or replace as required.

6.4.

If the orange/white wire continuity and 24-Pin connector are correct and there is no voltage at the orange

wire, replace the controller.

TEST PROCEDURE 17 – Walk Away Braking Relay

See General Warnings on page 1-2.

Walk Away Braking Relay Test with the CDT Handset

Turn the key switch to the OFF position and place the Forward/Reverse switch in the NEUTRAL position.

Connect the CDT to the vehicle.

See Plugging the CDT into the Vehicle, Section 11, Page 11-2.

Check the FAULTS Menu.

If a 15 RELAY DNC or 30 RELAY COIL FAULT is shown in the list, a walk away braking fault has occurred.

Walk Away Braking Relay Test without the CDT Handset

Turn the key switch to the OFF position and place the Forward/Reverse switch in the NEUTRAL position.

Slowly push the vehicle a short distance (about 3 feet (1 meter)).

You should hear the relay click and feel resistance as motor braking is applied. The reverse buzzer will also begin
pulsing. If neither of these conditions are present, test the Motor Speed Sensor.

See Motor Speed Sensor on

page 12-26.

If the Motor Speed Sensor is operational, replace the walk away braking relay.
