3 Move one of the test leads to the middle connection and turn the stem in both directions The range of
the readings should be approximately 1300-2500 Ohms or 2500-3700 Ohms, increasing and decreasing
through its full range
4 If you do not get these readings, replace the
Potentiometer
Service Note:
A simple shortcut method for testing and adjusting the pot resistance values is at
the 16 pin plug on the speed controller. Just disconnect the plug and back-probe
pins 5, 6 and 7 (wire colors VIO/BLK, BRN/RED and WHT/BLK). The controller
can be easily accessed by removing the electrical panel door located to the left of the
operator position.
Potentiometer Installation and Adjustment
Warning! The potentiometer adjustment sets the drive pedal for a neutral drive motor
operation. If the pot is not adjusted correctly, the machine will creep in either forward
or reverse.
1 Install the
Potentiometer
into
the
Mount Housing
and tighten the
attachment nut
2 Loosely connect
both the
Link Rod
to
the
Pedal
, and the
Throttle Lever
to the
Potentiometer
input

only. Check
the
Pedal
movement
It must move freely
in both forward and
reverse
4 See the
Potentiometer
terminal detail
Attach test leads
from a volt/ohm
meter to the VIO/
BLK and WHT/
BLK wire connection
points on the
Potentiometer
to check
its total resistance (for
example 4800 Ohms)
5 Connect the ohmmeter test leads to the VIO/BLK and BRN/RED
Potentiometer
connection points Use
a small screwdriver to turn the shaft end on the
Potentiometer
to half the total resistance previously
measured For example: 4800 Ohms divided by 2 = 2400 Ohms Then, without turning the shaft, tighten
the
Screw
and
Nut
to secure the setting at the
