Troubleshooting
Problem Possible Cause Corrective Action
1. Check that the power/ground cables
and control cables are connected
properly.
1. Connect the cables if they are not
connected.
2. Check for voltage at the pump motor
while the ignition switch is on and
the R
AISE
button is pressed on the
controller.
2. If voltage is present, the pump motor
has failed or the pump has seized.
Motor brushes may be replaced,
otherwise replace the pump/motor
assembly.
3. Check for power to the solenoid by
testing for voltage between both large
terminals and ground.
3. If voltage is not present between one
large terminal and ground, the cable
between the battery and the solenoid
is disconnected or broken.
4. Check for voltage between the other
large terminal of the solenoid and
ground while jumping power to the
small terminal with the white/black
wire.
4. If no voltage is present, the solenoid
has failed and must be replaced. If
voltage is present, the wire from the
small terminal of the solenoid to ground
may be disconnected or broken.
The pump motor does not run.
5. Test the power to the controller by
checking the voltage between the
black wire and ground at the white
9-pin connector.
5. If no voltage is present, power from
the relay has become disconnected.
If voltage is present, check the wiring
and controller switches.
The hydraulic pump continues to run while
the switch is in neutral.
1. The solenoid has failed in the closed
position.
1. Disconnect the controller while the
ignition is on. If the hydraulic pump
continues to run, the pump motor
start solenoid has failed in the closed
position. Quickly remove the power
to the plow by disconnecting the
power/ground cables to the plow.
Replace the solenoid. If the hydraulic
pump stops running, check the control
wiring for a short between the black
and white/black wire, or a failed control
switch. Connect, repair, or replace the
wiring or switch.
1. Check that the power/ground cables
and control cables are connected
properly.
1. Connect the cables if they are not
connected.
2. Check the flow-control valve. 2. If the flow-control valve is completely
closed, place the controller in neutral,
then open the flow-control valve.
3. Check the wiring on the valve block for
proper connections.
3. Refer to the wiring diagram included
with your Owner’s Manual .
4. Check for voltage between the solenoid
valve terminal and ground while the
ignition switch is on and the controller
is in the F
LOAT
position.
4. If voltage is present, the solenoid valve
or valve coil has failed. Replace the
valve or valve coil.
The plow does not lower.
5. Test the power to the control box by
checking the voltage between the
black wire and ground at the white
9-pin connector.
5. If no voltage is present, power from
the relays has become disconnected.
If voltage is present, check the wiring
and switch off the controller.
