Testing
1. Park machine on level surface and place traction le-
ver in the NEUTRAL position. Turn key switch to the
OFF position and remove key from the switch. Discon-
nect the battery pack (see Lithium Battery Pack Con-
nection in the General Information section of this
chapter).
2. Remove console cover from handle to allow access
to speed control potentiometer.
3. Disconnect machine wire harness connector from
the potentiometer. Remove potentiometer from ma-
chine using Figure 49 as a guide.
NOTE: Prior to taking small resistance readings with a
digital multimeter, short the meter test leads together.
The meter will display a small resistance value (usually
0.5 ohms or less). This resistance is due to the internal
resistance of the meter and test leads. Subtract this val-
ue from from the measured value of the component you
are testing.
4. Using a multimeter, measure resistances between
potentiometer terminals as follows (Fig. 50):
A. Verify that resistance between terminals B and C
is approximately 5000 ohms. Record measured re-
sistance.
B. Measure resistance between terminals A and C
and then measure resistance between terminals A
and B. Record these resistances. The total of the two
measured resistances should be approximately
5000 ohms.
C. Rotate the reel speed potentiometer to other set-
tings and repeat step B above. The total of the two
resistances should consist ently be approximately
5000 ohms.
D. If measured resistances are incorrect, replace
speed control potentiometer.
5. After testing is completed, secure potentiometer to
machine using Figure 49 as a guide. Secure wire har-
ness connector to potentiometer. Secure console cover
to handle.
6. Connect the battery pack (see Lithium Battery Pack
Connection in the General Information section of this
chapter).
