white wire with an insulation-piercing probe.
8.4. With the accelerator pedal fully up (not pressed), the multimeter should read approximately 1k
ohms.
8.5. Slowly press the accelerator pedal while monitoring the multimeter. The resistance should rise as
the pedal is pressed. When the pedal is all the way to the floor, the multimeter should indicate
between 5.67k ohms and 7.43k ohms.
8.6. Using a multimeter set for 20k ohms, connect the red (+) probe of the multimeter to the yellow wire
at the MCOR three-pin connector with an insulation piercing probe. Connect black (–) probe to the
white wire with an insulation-piercing probe.
8.7. With the accelerator pedal fully up (not pressed), the multimeter should indicate between 5.67k
ohms and 7.43k ohms.
8.8. Slowly press the accelerator pedal while monitoring the multimeter. The resistance should drop as
the pedal is pressed. When the pedal is all the way to the floor, the multimeter should indicate
approximately 1k ohms.
8.9. If the MCOR does not operate as described, replace the MCOR.
TEST PROCEDURE 5 – A1 AND A2 MOTOR VOLTAGE
See General Warning, Section 10, Page 10-1.
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, Section 10, Page 10-2.
2. With the batteries connected and using a multimeter set to 200 volts DC, place the black (–) probe on
the A2 motor terminal (white wire) and connect the red (+) probe to the A1 (green wire) motor terminal.
3. With Tow/Run switch in the RUN position, place the Forward/Reverse switch in the FORWARD position,
turn key switch to the ON position and slowly press accelerator pedal.
4. As the accelerator pedal is pressed, the voltage reading should increase from approximately 5 volts RMS
when the MCOR limit switch closes, to approximately 32-37 volts with the accelerator pedal fully pressed.
4.1. If there is no voltage reading, check the MCOR.
See Test Procedure 4 – MCOR Voltage on
page 11-19. Also check the continuity of the large posts of the solenoid. See Test Procedure 14
– Solenoid Continuity on page 11-37.
4.2. Disconnect the batteries and discharge the controller. See Disconnecting The Batteries on
page 10-3.
4.3. Check continuity on A1 and A2 motor terminal posts and continuity of the F1 and F2 motor terminal
posts. Also, check continuity of all motor wires. See Section 16 – Motor (Model 5BC59JBS6365
and Model 5BC59JBS6390).
TEST PROCEDURE 6 – TOW/RUN SWITCH
See General Warning, Section 10, Page 10-1.
Tow/Run Switch Test with the IQDM Handset
1. With the Tow/Run switch in the RUN position, connect the IQDM to the vehicle.
2. Immediately after the IQDM is connected to the vehicle, the screen should display a copyright notice and
the IQDM model number.
3. If the IQDM display screen is blank, drive the vehicle a short distance to activate the onboard computer.
4. If the vehicle will not operate, proceed to Tow/Run Switch Test without the IQDM Handset.
