– there is no voltage reading.
– the voltage reading is not above 3.50.
– the voltage reading does not fluctuate as the motor is turned.
TEST PROCEDURE 25 – Solenoid Contacts
See General Warning on page 1-1.
1. 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 Warning on page 1-1.
2. Turn the key switch to the ON position and place the Forward/Reverse switch in the FORWARD position.
3. Set a multimeter to 200 volts. Place the black (–) probe on the battery no. 8 negative post and place the red (+)
probe on the large post with the 6-gauge yellow wire.
4. With the pedal up, the reading should be 9.5 to 10.5 volts. If the voltage is higher, let the car sit for 5-10 minutes
to allow the capacitors to discharge to 9.5 to 10.5 volts.
5. Press the accelerator pedal. The voltage should read 48-50 volts with the pedal pressed. If the voltage does not
increase or goes to 0 volts with the pedal pressed, replace the solenoid.
TEST PROCEDURE 26 – Forward/Reverse Rocker Switch
See General Warning on page 1-1.
Forward/Reverse Rocker Switch Test with the IQDM Handset
1. Turn the key switch to the OFF position and place the Forward/Reverse switch in the NEUTRAL position.
2. Connect the IQDM to the vehicle. See Plugging the Handset into the Vehicle, Section 23, Page 23-1.
3. Test FORWARD INPUT.
3.1. Access the Monitor menu and select FORWARD INPUT by using the SCROLL DISPLAY buttons. The
IQDM should indicate OFF when the Forward/Reverse switch is in the NEUTRAL or REVERSE position.
3.2. Place the Forward/Reverse switch in the FORWARD position. The IQDM should indicate that FORWARD
INPUT is ON. If the IQDM indicates any other reading, check vehicle wiring. See Wiring Diagrams
beginning on page 22-2 . Also check the 24-pin connector at the speed controller. See 24-Pin Connector
on page 22-19.
4. Test REVERSE INPUT.
4.1. Access the Monitor menu and select REVERSE INPUT by using the SCROLL DISPLAY buttons. The IQDM
should indicate OFF when the Forward/Reverse switch is in the NEUTRAL or FORWARD position.
4.2. Place the Forward/Reverse switch in the REVERSE position. The IQDM should indicate that REVERSE
INPUT is ON. If the IQDM indicates any other reading, check vehicle wiring. See Wiring Diagrams on page
22-2. . Also check the 24-pin connector at the speed controller. See 24-Pin Connector on page 22-19.
5. If the IQDM displays readings other than those described above and the wiring is found to be correct, proceed to
the following procedure.
Forward/Reverse Rocker Switch Test without the IQDM Handset
1. Disconnect the batteries and discharge the controller. See Disconnecting the Batteries – Electric Vehicles,
Section 1, Page 1-4.
2. Remove the center dash panel.
2.1. Remove the plastic cap covering the mounting screw on each side of the center dash panel.
2.2. Loosen, but do not remove, the screw on each side of the center dash panel.
