POTENTIOMETER REMOVAL AND TESTING
WARNING!
Disconnect the machine’s battery pack connector (13) before servicing.
Potentiometer Removal
1 See Figure 8. Remove the (5) Screws (AB) securing the drive pedal mount assembly to the chassis then carefully lift the pedal assembly up
and lay it on its side.
2 Observe the (3) wires connected to the Drive Pedal Potentiometer (pot) (AC) and also the single GRN/YEL throttle ground wire (AD), note the
proper wire colors and their terminal connections for re-assembly. Then disconnect wiring and remove the pedal mount assembly from the
machine.
3 Remove the Link Rod (AE) from the Pedal (AF). Note: Be careful not to lose the link rod mounting hardware items (AG).
4 Loosen the Nut (AH) and Screw (AI) at the drive pedal Throttle Lever (AJ). Then pry the lever off from the end of the item (AC) potentiometer
shaft. Next remove the pot from the Mount Housing (AK).
Testing the Potentiometer
Note: The pot doesn’t have to be removed from the housing to test.
1 Test the potentiometer using an Ohmmeter (the pot specifi cation is 5K Ohms).
2 Connect the meter leads to each of the outside connections on the potentiometer. The meter should read approximately 5000 Ohms (plus or
minus 500 Ohms).
3 Next, move one of the test leads to the middle connection and turn the stem in both directions. The range of the readings should be approximately
0-5000 Ohms or 5000-0 Ohms increasing and decreasing through its full range.
4 If you do not get these readings replace the potentiometer.
