SPEED CONTROL CIRCUIT
Test Procedure 8 - Multi-step Potentiometer:
1. Disconnect the black and white No. 18 wires that are attached to controller terminals "2" and "3" (termi-
nals "B" and "C" on early model vehicles) (see wiring diagram Figure 17-2, Page 17-3 to identify ter-
minals) 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 go up in six steps:
1st Step:
2nd Step:
3rd Step:
4th Step:
5th Step:
6th Step:
NOTE
• 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.
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 in Figure 17-6.
6. Reconnect half-speed reverse resistor to half-speed reverse limit switch on the Forward/Reverse switch.
Test Procedure 9 - Continuously Variable
Potentiometer:
1. Disconnect the three-wire connector (connects
the potentiometer to the Forward/Reverse wire
harness) from the Forward/Reverse wire har-
ness. The connector emerges from under the
floorboard into the battery compartment below
the charger receptacle on the front seat support
panel (Figure 17-9).
2. Connect multi-meter, set to "ohms" position,
between the purple and yellow wire terminals.
Resistance should read between 150 and 300
ohms at exactly the point that the limit switch is
activated.
3. Depress the accelerator to the floor; potentiome-
ter resistance should measure between 4600
and 6400 ohms.
300 ohms (approx.)
690 ohms (approx.)
990 ohms (approx.)
1740 ohms (approx.)
2740 ohms (approx.)
4940 ohms (approx.)
