6.1. If the voltage reading is correct, proceed to step 7.
6.2. If reading is zero volts, check red wire continuity and Tow/Run switch.
See Test Procedure 2 –
Onboard Computer Solenoid Lockout Circuit on page 21-11. See also Test Procedure 6 –
Tow/Run Switch on page 21-15.
6.3. If the continuity readings are not correct, repair or replace the red wire.
6.4. If the continuity readings are correct, proceed to step 7.
7. 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).
7.1. If the voltage reading is correct, replace the reverse buzzer.
7.2. If reading is zero volts, check orange/white wire continuity and connection at Pin 10 in 23-Pin con-
nector.
7.3. If there is no continuity in the orange/white wire, or the Pin 10 terminal in the 23-Pin connector is
not properly seated, repair or replace as required.
7.4. If the orange/white wire continuity and 23-Pin connector are correct and there is no voltage at the
orange wire, replace the controller.
TEST PROCEDURE 17 – REBOOTING THE ONBOARD COMPUTER
See General Warning on page 1-1.
It is possible the Onboard Computer (OBC) can become “locked up,” causing the OBC solenoid lockout circuit
to malfunction. If this condition is suspected, restart the computer as follows:
1. Disconnect the battery cables as instructed. See WARNING “To avoid unintentionally starting...” in
General Warning on page 1-1. See following NOTE.
NOTE: Wait at least 90 seconds for the capacitors in the speed controller to discharge. The capacitors in
the speed controller must be fully discharged in order to reboot the OBC.
2. Place the Tow/Run switch in the TOW position and connect the battery cables, positive (+) cable first.
Tighten battery terminals to 110 in-lb (12.4 N·m) and coat terminals with Battery Terminal Protector Spray
(CCI P/N 1014305) to minimize corrosion.
3. Place Tow/Run switch in the RUN position.
4. Test drive the vehicle. If the problem has been fixed, the vehicle will function normally. If the problem still
exists, refer to Wiring Diagram on page 21-2.
TEST PROCEDURE 18 – BATTERY WARNING LIGHT
See General Warning on page 1-1.
1. Reboot the OBC and drive the vehicle a short distance. When vehicle is first driven, the battery warning
light should illuminate for 10 seconds. See Test Procedure 17 – Rebooting the Onboard Computer
on page 21-32. If the battery warning light does not illuminate when rebooting the OBC, proceed to step
2.
2. Turn key switch OFF, place Tow/Run switch in TOW and place Forward/Reverse rocker switch in NEU-
TRAL.
3. Disconnect the six-pin connector at the OBC.
4. Remove the wedge lock from the six-pin connector housing that is connected to the vehicle wire harness.
Remove the brown/white wire from the connector plug.
