ELECTRICAL SYSTEM AND TESTING: ELECTRIC
VEHICLES Test Procedures

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.
8.10. Connect the batteries. See Connecting the Batteries – Electric Vehicles, Section 1, Page 1-4.
TEST PROCEDURE 5 – A1 and A2 Motor Voltage
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. With the batteries connected and using a multimeter set to 200 volts DC, place the black (–) probe on the A2
(1) motor terminal (white wire) and connect the red (+) probe to the A1 (2) motor terminal (green wire)
(Figure
22-8, Page 22-15) .
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 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 or if there is no increase in voltage as the pedal is pressed, check the MCOR.
See MCOR Voltage on page 22-13. Also check the continuity of the large posts of the solenoid. See
Solenoid Contacts on page 22-33.
4.2. Disconnect the batteries and discharge the controller. See Disconnecting the Batteries – Electric
Vehicles, Section 1, Page 1-4.
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 See Section 27 – Motor (Model DA5-4006): Electric
Vehicles. .
4.4. Connect the batteries. See Connecting the Batteries – Electric Vehicles, Section 1, Page 1-4.
