05
Left brush motor contactor coil
overload
Contactor
K4
is for the left motor on
the three-motor decks. The nominal
coil resistance is 94 ohms for all
three motor contactors.
1. Check for a
K4
coil wiring problem or a short circuit*
(wire colors VIO and GRA/RED).
2. Check the coil resistance. If the resistance is below
75 ohms, replace the coil.
06
Center brush motor contactor coil
overload
Contactor
K3
is for the center motor
on three-motor decks.
K3
is for the
left motor on two-motor decks.
1. Check for a
K3
coil wiring problem or a short circuit*
(wire colors VIO and WHT/VIO).
2. Check the coil resistance. If the resistance is below
75 ohms, replace the coil.
07
Right brush motor contactor coil
overload
Contactor
K2
is for the right motor
on two- or three-motor decks.
K2
is
the only contactor on a single-motor
decks.
1. Check for a
K2
coil wiring problem or a short circuit*
(wire colors VIO & YEL/BLU).
2. Check the coil resistance. If the resistance is below
75 ohms, replace the coil.
08
Scrub deck actuator overload
•
Normal current load is 1-3 amps.
•
Max current load is 6 amps.
•
Max current with no load is 1.4
amps.
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.
09
Vacuum motor overload
Normal current load for one motor is
16-20 amps. Normal current load for
two motors is 32-40 amps.
1. Check for debris in the vacuum motor(s).
2. Check for worn carbon brushes - replace brushes.
3. Defective motor bearings - repair or replace.
4. Check for a short circuit* in the vacuum motor or
wiring - repair or replace.
10
K1
Vacuum motor contactor
coil overload. The nominal coil
resistance is 100 ohms.
1. Check for a
K1
coil wiring problem or short circuit*
(wire colors VIO and BLU).
2. Check the coil resistance. If the coil resistance is
below 80 ohms, replace the coil.
11
Squeegee actuator overload
•
Normal current load is 1-2 amps.
•
Max current load is 6 amps.
•
Max current with no load is 1.4
amps.
1. Check for binding or frozen squeegee lift linkage and
excessive weight on the squeegee mount.
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.
12
L1
Solution solenoid overload
The nominal coil resistance is 74
ohms.
1. Check for a wiring problem or short circuit*.
2. Check the coil resistance. Replace the solution
solenoid if the coil resistance is lower than 58 ohms.
