K6
Side broom motor contactor coil
short to ground
1. Disconnect the
K6
coil wiring (wire colors VIO and
BRN/BLK) and check to see if the code disappears.
−
If the code disappears, replace the
K6
contactor.
−
If the code does reappear, test the wiring for a short
back to the battery ground. Repair or replace the
defective wire.
2. If the above test doesn’t remove the code, substitute
a new A2 control board assembly.
38
Side broom actuator motor open
1. Use an ohmmeter to check for an open circuit in the
M4
side broom actuator and its wiring (wire colors
GRA/VIO and GRN/ORN). If defective, repair or
replace.
2. Test for 36V at side broom actuator. If 0 Volts, check
the A2 control board assembly.
39
Auxiliary motor contactor coil open
1. Check for an open circuit in the
K5
coil and wiring
(wire colors YEL/BRN and BLK/ORN).
2. Test for 36V at the
K5
coil. If 0 Volts, check the A2
control board assembly.
40
K5
Auxiliary motor contactor coil
short to ground
1. Disconnect the
K5
coil wiring (wire colors YEL/
BRN and BLK/ORN) and check to see if the code
disappears.
−
If the code disappears, replace the
K5
contactor.
−
If the code does reappear, test the wiring for a short
back to the battery ground. Repair or replace the
defective wire.
2. If the above test doesn’t remove the code, substitute
a new A2 control board assembly.
41
Back-up alarm open
1. Use an ohmmeter to check for an open circuit in the
H1
back-up alarm and its wiring (wire colors ORN/
BRN and BLU/WHT). If defective, repair or replace.
2. Test for 36V at the back-up alarm. If 0 Volts, check the
A2 control board assembly.
42
Back-up alarm short to ground
1. The Back-up alarm and/or its +36V power feed is
shorted to ground. Test the positive wire to ground
for short circuit* (wire colors ORN/BRN b and
BLU/WHT battery -). Repair or replace the defective
wiring.
2. Disconnect the alarm and test to see if the circuit
wiring is still causing an error code (shorted). If not,
replace the back-up alarm.
* Short Circuit definition:
•
A short circuit is a parallel path of very low resistance, often caused accidentally
•
With low resistance there is an excessive amount of current
• The excessive current will either melt the wires or open a fusible link.
