Test Procedures
TEST PROCEDURE 14 – Pins 8 and 16
See General Warnings on page 1-1.
Pins 8 and 16 in the 16-pin connector provide a connection point for the Forward/Reverse rocker switch to the speed
controller. The switch provides a +48 volt signal to the speed controller through pin 8 when the Forward/Reverse
switch is in the FORWARD position and provides a +48 volt signal on pin 16 when the Forward/Reverse switch is in
the REVERSE position.
1. Disconnect the batteries and discharge the controller. See Disconnecting the Batteries – Electric Vehicles
on page 1-3.
2. Place chocks at the front wheels and lift the rear of the vehicle with a chain hoist or floor jack. Position jack stands
under the frame crossmember between the spring mount and side stringer, just forward of each rear wheel. See
WARNING "Lift only one end..." in General Warnings on page 1-1.
3. Disconnect the 16-pin connector at the speed controller.
4. Using a multimeter set for 200 volts DC, insert the red (+) probe of the multimeter into pin 8 (brown wire) of the
16-pin connector. See following CAUTION. Using an alligator clip, connect the black (–) probe to the B– terminal
of the speed controller (Figure 14-16, Page 14-29).
CAUTION
• Do not fully insert probes into the 16-pin plug. Doing so can result in a poor connection.
1. Place the Tow/Run switch in the TOW position and connect the batteries. See Connecting the Batteries –
Electric Vehicles on page 1-3.
2. Place the Tow/Run switch in the RUN position and the Forward/Reverse switch in the NEUTRAL position. The
multimeter should indicate zero volts DC at this time.
3. While monitoring the multimeter, place the Forward/Reverse switch in the REVERSE position. The multimeter
should still indicate zero volts.
4. Place the Forward/Reverse switch in the FORWARD position. The multimeter should indicate full battery voltage
(approximately 48 volts).
5. Insert the red (+) probe of the multimeter into pin 16 (blue wire) of the 16-pin connector. Leave the black (–) probe
(alligator clip) connected to the B– terminal of the speed controller. See previous CAUTION.
6. Place the Forward/Reverse switch in the NEUTRAL position. The multimeter should indicate zero volts DC
at this time.
7. While monitoring the multimeter, place the Forward/Reverse switch in the FORWARD position. The multimeter
should still indicate zero volts.
8. Place the Forward/Reverse switch in the REVERSE position. The multimeter should indicate full battery voltage
(approximately 48 volts).
9. If any other reading is obtained, check the following items:
– Continuity of the wires in the wire harness
– Forward/Reverse switch for proper operation. See Test Procedure 23 – Forward/Reverse Rocker Switch
on page 14-35.
– Tow/Run switch for proper operation. See Test Procedure 6 – Tow/Run Switch on page 14-19.
