ELECTRICAL SYSTEM TROUBLESHOOTING: IQ
PLUS ELECTRIC VEHICLES
Detail A: Front of 24-Pin Connector
Pins 10 and 11
See General Warnings on page 1-1.
Pins 10 and 11 in the 24-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 10 when the Forward/Reverse
switch is in the FORWARD position and provides a +48 volt signal on pin 11 when the Forward/Reverse switch is in
the REVERSE position.
1. Disconnect the batteries and discharge the controller. See Disconnecting the Batteries – Electric Vehicles,
Section 1, Page 1-4.
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 24-pin connector at the speed controller.
4. Set a multimeter to 200 volts DC, insert the red (+) probe of the multimeter into pin 10 (brown wire) of the 24-pin
connector. See following CAUTION. Using an alligator clip, connect the black (–) probe to the B– terminal
of the speed controller (Figure 12-19, Page 12-38).
CAUTION
• Do not fully insert probes into the 24-pin plug. Doing so can result in a poor connection.
5. Place the Tow/Run switch in the TOW position and connect the battery cables, positive (+) cable first. See
Connecting the Batteries – Electric Vehicles, Section 1, Page 1-4.
6. 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.
7. While monitoring the multimeter, place the Forward/Reverse switch in the REVERSE position. The multimeter
should still indicate zero volts.
