4.
Set a multimeter to 20k ohms. Insert the red (+) probe of the multimeter into pin 15 (yellow wire) of the 24-pin
connector.
See following CAUTION.
Insert the black (–) probe into pin 14 (purple/white wire) of the 24-pin
connector
.
CAUTION
• Do not fully insert probes into the 24-pin plug. Doing so can result in a poor connection.
5.
With the accelerator pedal fully up (not pressed), the multimeter should read approximately 1k ohms.
6.
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.
7.
Set a multimeter to 20k ohms. Insert the red (+) probe of the multimeter into pin 15 (yellow wire) at the 24-pin
connector. Connect the black (–) probe into pin 13 (white wire).
See previous CAUTION.
8.
With the accelerator pedal fully up (not pressed), the multimeter should indicate between 5.67k ohms and
7.43k ohms.
9.
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.
10. If any other reading is observed, check the continuity of the wires in the wire harness.
11. Connect the batteries.

TEST PROCEDURE 12 – Pin 2
See General Warning on page 1-1.
Pin 2 in the 24-pin connector provides a connection point for the solenoid lockout circuit from the onboard computer to
the speed controller.
1.
Disconnect the batteries and discharge the controller.
