WHEEL DRIVE SYSTEM
(5K) POTENTIOMETER (R1) INSTALLATION AND ADJUSTMENT (CONTINUED)
5
Reconnect the ohmmeter test leads to the pot wiper and low terminal connections and adjust (turn the pot) to obtain half of pot’s total resistance. This will
accurately set the true neutral drive paddle operator position.
6
Tighten the anchor nut secure. Note: Do not turn the potentiometer shaft when tightening. Next re-attach all the wiring to both the pots and re-install the
cover.
7. Reconnect the battery connector and turn the key switch on and test the drive system for proper FWD and REV operations. Note: The covers outside mounted
speed limit knob should be turned to the full speed position for testing. If the display panel shows the 03 fault code the Potentiometer’s are either not wired
correctly or the R1 pot is not set to its neutral setting.
(100K) POTENTIOMETER (R2) TESTING AND REMOVAL
WARNING!
Disconnect the battery connector before servicing.
Note: The potentiometer (pot) doesn’t have to be removed from the drive paddle cover to test.
Test Procedure
FIGURE 8

1
See Figure 7.
Remove the front drive paddle Cover
(G)
from the rear housing
(H)
held together with (4) item
(I)
Screws. Note the cover will have the speed limiting pot
(R2)
mounted to it; observe the (3) wires to reassemble
and then separate them to complete the removal of the
cover.
2 Test
the
(R2)
potentiometer’s resistance values using
an ohmmeter, its speci
fi
cation is 100,000 ohms (plus
or minus 10%). Connect the meter leads to each of the
outside connections on the potentiometer, should read
approximately 100,000 ohms. Next, take one of the test
leads and connect to the middle terminal, then turn the
stem both directions. The resistance value will change
(vary) increasing and decreasing through its full range of 0-
100,000 ohms and 100,000-0 ohms approximately. If you
do not get similar readings replace the potentiometer.
R2 Potentiometer Removal
3
See Figure 10.
Remove the Set Screw
(L)
(1/16” wrench)
and pull off the Adjustment Knob
(M)
from the stem of the
pot.
4 Remove the pot’s anchor nut (1/2 inch wrench) then
remove the
(R2)
Pot from the drive paddle cover.
