4. Test the key switch.
4.1. Access the Test menu and select KEY INPUT by using the SCROLL DISPLAY buttons. The IQDM should
indicate OFF when the key switch is in the OFF position.
4.2. While monitoring the IQDM display screen, turn the key switch to the ON position. The IQDM should
indicate ON.
4.3. If the IQDM does not indicate that KEY INPUT is ON when the key switch is in the ON position, proceed to
the following procedure, Key Switch and MCOR Limit Switch Circuit Test without the IQDM Handset. If
the key switch functions as described, proceed to the following step. See following NOTE.
NOTE: The key switch MUST function properly in order to test the MCOR limit switch with the IQDM handset.
5. Test the MCOR limit switch.
5.1. Select FOOT INPUT on the Test menu by using the SCROLL DISPLAY buttons on the IQDM.
5.2. The IQDM should indicate that FOOT INPUT is OFF when the accelerator pedal is not pressed, regardless
of the key switch position.
5.3. With the key switch in the ON position, press the accelerator pedal. The IQDM should indicate that FOOT
INPUT is ON when the accelerator pedal is pressed.
6. If any reading is obtained that is not described in steps 4 and 5, perform the following steps:
6.1. Check the wiring of the key switch and MCOR. See Wiring Diagrams on page 14-3.
6.2. Check the continuity of the key switch wires and the MCOR limit switch wires.
7. If the problem was not found, proceed to the following procedure, Key Switch and MCOR Limit Switch Circuit
Test without the IQDM Handset.
Key Switch and MCOR Limit Switch Circuit Test without the IQDM Handset
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 rails just forward of each spring mount. See WARNING "Lift only one end..." in
General Warnings on page 1-1.
3. Turn the key switch to the OFF position and place the Forward/Reverse switch in the NEUTRAL position.
4. Test the key switch.
4.1. Remove the instrument panel. See Key Switch Removal, Section 17, Page 17-1.
4.2. Using a multimeter set to 200 ohms, place the red (+) probe on the key switch terminal with the blue wire.
Place the black (–) probe on the other key switch terminal.
4.3. With the key switch in the OFF position, the multimeter should indicate that continuity is not present.
4.4. With the key switch in the ON position, the multimeter should indicate that continuity is present.
4.5. If any other reading is obtained, replace the key switch. See Key Switch Removal on page 17-1.
4.6. If the key switch operates as described in the previous steps, install the instrument panel in the reverse
order of removal and proceed to the following step.
5. Test the MCOR limit switch. See following NOTE.
NOTE: Make sure that the key switch is operating correctly and that the key switch and instrument panel are properly
installed before proceeding.
5.1. With batteries connected and using a multimeter set to 200 volts DC, place the black (–) probe on the
battery no. 4 (4 x 12-Volt battery set) or battery no. 6 (6 x 8-Volt battery set) negative post and place the red
(+) probe (with insulation-piercing probe) on the green wire close to the two-pin connector on the MCOR.
