Testing the Speed Control Potentiometer (continued)

2. Disconnect the battery pack; refer to

Connecting the Lithium Battery Pack

(page 5–7)

.

3. Remove the console cover from the handle to get access to the speed

control potentiometer.

4. Disconnect the machine wire harness connector from the potentiometer, and

remove the potentiometer from the machine (

Figure 110

).

Note:

Before taking the small resistance readings with a digital multimeter,

short the multimeter test leads together. The meter displays a small
resistance value (usually 0.5 ohms or less). This resistance is because of the
internal resistance of the multimeter and test leads. Subtract this value from
the measured value of the component that you are testing.

Terminal C

5. Use a multimeter, measure the resistances between the potentiometer

terminals as follows (

Figure 111

):

A. Check that the resistance between the terminals B and C is approximately

5,000 ohms. Record the measured resistance.

B. Measure the resistance between the terminals A and C and then measure

the resistance between the terminals A and B. Record these resistances.
The total of the 2 measured resistances should be approximately 5,000
ohms.

C. Rotate the reel speed potentiometer to other settings and repeat the step

B

. The total of the 2 resistances should consistently be approximately

5,000 ohms.

D. If measured resistances are incorrect, replace the speed control

potentiometer.

6. After you complete the testing, secure the potentiometer to the machine

(

Figure 110

). Secure the wire harness connector to the potentiometer.

Secure the console cover to the handle.

7. Connect the battery pack; refer to
