TROUBLESHOOTING GUIDE

Possible Symptom

1

  Forward/Reverse auto accessory functions do not work or activate slowly (do not function properly).  Examples: Main broom, side brooms, 

scrub motors, vacuum motor and dust control motor.

Electrical Control Circuit

Note: Do all testing with the key switch ON, hopper lowered and drive pedal activated (forward/reverse).

Service Adjustment Note:

 A drive pedal sensor setting that is set too low will not target (match) the drive pedal neutral return position (dead-

band too narrow) and the engine will not start.  Too high of a setting will increase the neutral range (dead-band too wide) and delay the activation 

of turning on the auto sweep and scrub functions when the drive pedal is moved out of an excessively wide programmed neutral range.

Machine drive auto

function does not work

Place the pedal in forward or

reverse position. Check on the

A1 control board. Is the green

neutral indicator light on?

Is the hopper yellow indicator

light on at the A1 board?

Adjust or replace

magnetic switch

S12.

Does light come

on?

No

Yes

Yes

Replace the A1 Control Board

Replace pedal

sensor or wiring

(switch is open).

No

Yes

No

Replace

A1 board

No

Reset drive pedal sensor dead band set-

ting. Sensor has a range of 1-9

factory setting is 2-5.

Turn key switch off, press and hold the

engine speed switch then turn the key on.

Setting should be at 2-5. To change setting

press the speed switch, To exit turn key

off. Does the light come on and

auto functions operate?
