To properly adjust the potentiometer, measure the

potentiometer’s maximum ohm value using an

ohmmeter then divide the max. value by two to

find the center (neutral) position (Figure 9).

Example: Maximum value 5.0K ohms



2.5K ohms (+/- 10%) center position.

With the machine’s control grips at the neutral

position, rotate the body of the potentiometer up

or down until the reading on the ohmmeter is at

the center (neutral) position. Tighten nut.

2.5K (+/- 10%)

10. Connect the new potentiometer wire harness

to the new wire harness wires (white to 39/white,

red to1B/red and black to13AA/black) (Figure

replace it with wire 1C/Red from the new wire

harness as shown (Figure 12). The disconnected

brown wire is not required for this kit. Wrap

electrical tape around the unused terminal.

and replace it with wire 1C/Red from new harness

(figure not shown). Also disable CB1 by removing

wire connections within the machine’s wire

harness as shown (Figure 13). Remove the

electrical tape and disconnect the orange wire

from blue wires.

The disconnected orange wire is not required for

this kit. Wrap electrical tape around the unused

terminal. The disconnected orange wire disables

the 10A circuit breaker (CB1). CB1 is not

required for this kit.

NOTE: For early models, if harness is not

equipped with charger interlock wires as shown,

refertoStep13NOTE.
