Test Procedures
TEST PROCEDURE 5 – A1 and A2 Motor Voltage
See General Warnings 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 rails just forward of each spring mount. See WARNING "Lift only one end..." in General
Warnings on page 1-1. See also following WARNING.
WARNING
• Keep people and equipment clear from rotating rear wheels. Do not allow persons under the car.
Contact with rotating rear wheels could result in serious personal injury.
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 48 volts RMS with the accelerator pedal fully pressed.
See following NOTE.
NOTE: Voltage can vary depending on controller speed setting as well as which zone a Guardian equipped vehicle
is located.
Example: Speed setting 1 may only read 30 volts.
4.1. If there is no voltage reading, check the MCOR. See MCOR Voltage on page 14-16. Also check the
continuity of the large posts of the solenoid. See Solenoid Continuity on page 14-35.
4.2. Disconnect the batteries and discharge the controller. See Disconnecting the Batteries – Electric
Vehicles on page 1-3.
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 20 – Motor (Model EJ4-4001 and EJ8-4001A).
