ELECTRICAL SYSTEM
OUTPUT CONTROLS (CONTINUED):
Scrub On Switch (I):
This switch is used to control the output to the scrub deck lift actuator. Pressing and releasing this switch will cycle the actuator output through four states. These
are:
1 – Output off, direction = up
2 – Output on, direction = down (display will show down arrow)
3 – Output off, direction = down
4 – Output on, direction = up (display will show up arrow)
When the output is in state 1, the actuator output is turned off. The scrub on indicator
(K) should be off. If the indicator is fl ashing green, this indicates that the control
is sensing current fl ow through the actuator (shorted output driver, control error). If the scrub on switch (I) was the last switch pressed, it is possible to momentarily
activate the actuator output using the Wand Switch (E) . This can be used to jog the actuator to allow precise positioning of the actuator. Note that the actuator can
only move in this situation if it is not at its down limit.
When the output is in state 2, the actuator output is turned on. The scrub on indicator
(K) should be green or fl ashing green. The indicator will be a steady green if
the control senses current fl ow through the actuator. It will fl ash green if no actuator current fl ow is sensed (actuator at limit, open circuit, open output driver). The
Wand Switch (E) has no effect in this state.
When the output is in state 3, the actuator output is turned off. The Scrub On indicator (K) should be off. If the indicator is fl ashing green, this indicates that the
control is sensing current fl ow through the actuator (shorted output driver, control error). If the scrub on switch (I) was the last switch pressed, it is possible to
momentarily activate the actuator output using the Wand Switch (E) . This can be used to jog the actuator to allow precise positioning of the actuator. Note that the
actuator can only move in this situation if it is not at its up limit.
When the output is in state 4, the actuator output is turned on. The Scrub On indicator
(K) should be yellow or fl ashing yellow. The indicator will be a steady yellow
if the control senses current fl ow through the actuator. It will fl ash yellow if no actuator current fl ow is sensed (actuator at limit, open circuit, open output driver). The
Wand Switch (E) has no effect in this state.
Vacuum Switch (C):
This switch is used to toggle the state of the vacuum motor. Pressing and releasing this switch will alternately turn the vacuum motor on and off. The Vacuum System
Indicator
(N) provides the following status information:
Off - Vacuum motor output is off and there is no vacuum motor current sensed.
Steady Green - Vacuum motor output is on and there is normal vacuum motor current sensed.
Brief On Green Flash – Vacuum motor output is off and vacuum motor current is being sensed (abnormal condition).
Check for voltage at the BLU wire on K2 contactor to battery ground.

If any voltage is present, replace K2 contactor.

No voltage, replace the Main control board.

Brief Off Green Flash – Vacuum motor output is on and vacuum motor current is not being sensed (abnormal condition).
Check Vacuum Motor wiring plug, disconnection.

Check for voltage at the RED wire on K2 contactor to battery ground. If no voltage is present repair the RED wire.

Check for voltage at the BLU wire on K2 contactor to battery ground. If no voltage is present replace the K2 contactor.

Check the BLU wire of the main harness connector at the vacuum motor to battery Negative. If no voltage, repair or replace wire.

Check the BLK wire of the main harness connector at the vacuum motor to battery Positive. If no voltage, repair or replace wire.

Flashing Yellow – Vacuum motor overload has occurred.
Check for an open circuit in the small ORG current sense wire.

To con fi rm an overload, disconnect the motor plug from the main harness, run 30-amp fused test leads from the batteries to the motor and perform an amp

draw test. Normal current load 36V 23-25 amps.
Check for debris in the vacuum motor.

Worn carbon brushes.

Defective motor bearings.

Check for short circuit* in vacuum motor or wiring. Repair or replace

Solution Switch (B):
This switch is used to toggle the state of the solution system. Pressing and releasing this switch will alternately turn the solution pump and solenoid on and off. The
Solution System Indicator
(O) provides the following status information:
Off - Solution output is off.
Steady Green - Solution output is on (solution pump is on and solenoid valve is open)
Flashing Yellow – Solution solenoid coil overload has occurred.
Detergent System Switch (F):
This switch is used to toggle the state of the detergent pump. Pressing and releasing this switch will alternately turn the detergent pump on and off. The Detergent
System Indicator
(P) provides the following status information:
Off – Detergent pump is off.
Steady Green – Detergent pump is on (cycling).
