SPEED CONTROL CIRCUIT
Test Procedure 8 - Multi-step Potentiometer:
1. Disconnect the black and white 18 gauge wires that are attached to controller terminals “2” and “3” (ter-
minals “B” and “C” on early model vehicles) (see wiring diagram Figure 20-2, Page 20-3 to identify
terminals) and connect ohm meter to wires.
2. Disconnect half-speed reverse resistor from the half-speed reverse limit switch.
3. Measure resistance while pressing the accelerator pedal. The measured resistance should increase in
six steps:
1st Step:
300 ohms (approx.)
2nd Step:
690 ohms (approx.)
3rd Step:
990 ohms (approx.)
4th Step:
1740 ohms (approx.)
5th Step:
2740 ohms (approx.)
6th Step:
4940 ohms (approx.)
4. If the resistance steps were not correct and the accelerator pedal is properly adjusted, then replace
multi-step potentiometer.
5. Reconnect black and white wires to terminals “2” and “3” (“B” and “C”) as shown (Figure 20-6).
6. Reconnect half-speed reverse resistor to half-speed reverse limit switch on the Forward/Reverse
switch.
Test Procedure 9 - Continuously Variable Potentiometer:
To test the potentiometer, perform the actuator adjustment procedure on page 6-19. If the readings are not
correct after the adjustment has been made, the potentiometer assembly will need to be replaced.
• IT MAY BE DIFFICULT TO DETECT THESE STEPS. HOWEVER, IF AN INCREASE IN RESIS-
TANCE FROM 0 TO (APPROXIMATELY) 5000 OHMS IS OBTAINED WHEN THE ACCELERATOR
PEDAL IS DEPRESSED FROM THE REST POSITION TO FULL SPEED POSITION WITHOUT
EXCEEDING (APPROXIMATELY) 7000 OHMS DURING OR AT THE END OF ACCELERATOR
TRAVEL, THEN THE SPEED SWITCH RESISTOR ASSEMBLY IS IN GOOD CONDITION.
