ELECTRICAL SYSTEM
BATTERY STATUS DISPLAY:
The display will show the battery voltage. This display is accurate to /- 0.15 volts. Therefore, the voltage displayed may not correlate precisely to a high-
accuracy, calibrated voltmeter.
OUTPUT CONTROLS:
The control panel switches are used to control various output functions of the main control unit. Below is a list of each switch and the function it controls. Following
the list is a detailed description of each function.
Scrub Off Switch (H) : Controls the brush motors.
Scrub On Switch (I) : Controls the scrub deck lift actuator.
Vacuum Switch (C) : Controls the vacuum motor.
Wand Switch (E) : Used to jog the scrub deck lift actuator.
Solution Switch (B) : Turns on the solution pump and solenoid valve.
Detergent System Switch (F) : turns on the detergent pump.
Scrub Off Switch (H):
This switch is used to toggle the state of the brush motor. Pressing and releasing this switch will alternately turn the brush motor on and off. The indicator (J) provides
the following status information:
Off – Brush motor output is off and there is no brush motor current sensed.
Steady Green – Brush motor output is on and there is normal brush motor current sensed.
Brief On Green Flash – Brush motor output is off and brush motor current is being sensed (abnormal condition).
Check for voltage at the WHT wire on K1 contactor to battery ground.

If any voltage is present, replace K1 contactor.

No voltage, replace the Main control board.

Brief Off Green Flash – Brush motor output is on and brush motor current is not being sensed (abnormal condition).
Check brush motor wiring plugs.

Check one of the BLK wires of the main harness connector at the brush motor to battery Positive. If no voltage repair or replace wire.

Check one of the WHT wires of the main harness connector at the brush motor to battery Neg. If no voltage repair or replace wire.

Check for voltage at the RED wire on K1 contactor to battery ground. If no voltage is present repair the RED wire.

Check for voltage at the WHT wire on K1 contactor to battery ground. If no voltage is present replace the K1 contactor.

Flashing Red – Brush motor overload has occurred.
Check to see that the correct brush type is selected (should display “Adhancer”).

Check for binding in rotation of brushes.

Check the negative supply cable at the brush motor for a wiring problem or incorrect modi fi cations.

Check for open circuit in the small WHT/GRA current sense wire.

Check for short circuit* in brush motor or wiring.

Inspect scrub brush drive and idler bearings for excessive wear.
