Correction
A fault will occur if scrub deck sensor resistor is
unplugged or damaged. Check the resistor wiring for an
open and substitute a new resistor and test scrub deck
for correct operation. Note that there are four different
resistor values used on the different deck types. See the
electrical diagram decal for the correct specification for
the resistor to replace.
Observe the blue flashing light detergent indicator light,
then refer to the
Wheel Drive, Traction
troubleshoot the drive system.
1. Check for binding in the rotation of the brushes and
incorrect brush deck lift actuator operation.
2. Check the negative supply cable at the brush motor
for a wiring problem, and also the small BRN current
sense wire in the harness and A2 pin J2-2.
3. Check for a short circuit* in the brush motor or wiring.
On cylindrical models check for excessive belt tension
and the condition of the idler bearing.
1. Check for a
coil wiring problem or a short circuit*
K4
(wire colors VIO and GRA/RED).
2. Check the coil resistance. If the resistance is below
75 ohms, replace the coil.
1. Check for a
coil wiring problem or a short circuit*
K3
(wire colors VIO and WHT/VIO).
2. Check the coil resistance. If the resistance is below
75 ohms, replace the coil.
1. Check for a
coil wiring problem or a short circuit*
K2
(wire colors VIO & YEL/BLU).
2. Check the coil resistance. If the resistance is below
75 ohms, replace the coil.
1. Check for binding or a frozen brush lift linkage and
excessive weight on the brush deck.
2. Check for a short circuit* in the actuator motor and
wiring. Repair or replace.
To test the actuator, disconnect the motor plug and
attach the actuator power cord adapter (p/n 56407502)
and perform an amp draw test. Compare readings to the
current load specifications.

– This switch controls the solution solenoid and solution control pump.
Solution Switch
Pressing and releasing this switch will alternately turn the solution solenoid and
