Testing the Throttle and Clutch Bail Potentiometers (continued)

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

(

). Secure the wire harness connector to the potentiometer. Secure

the handle cover to the handle.

Note:

When re-installing the potentiometers, a minimum voltage reading of

0.5V for proper function is required. This can be read in the InfoCenter. The
adjustment is completed by rotating the potentiometers in the mounting slots
until the minimum voltage at the neutral position is achieved.

7. Connect the battery pack; refer to
