POTENTIOMETER REMOVAL AND TESTING
WARNING!
Disconnect the machine’s battery pack connector (13) before servicing.
Potentiometer Removal
1 See Figure 9. 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 speci fi 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.
