Troubleshooting Guide

PROBLEM

DIAGNOSTIC CHECK

RESULT

Check power/ground
cables and control cable
are connected properly.

Connect.

Check wiring on valve
block for proper
connections.

Refer to the manifold wiring
diagram in this manual.

Load test battery.

Replace battery if weak or
defective.

Check pressure at
pressure port of pump.

If pressure is less than
2500 psi (at end of lift).
Motor brushes may be
defective, pump pressure
relief valve may be
contaminated, damaged, or
set less than 2500 psi,
pump may be worn.

Check LIFT Solenoid
Valve.

Lift solenoid valve not
opening completely.
Replace.

Check wiring and switch
box control.

5. While trying to raise plow,

wing(s) extend prior to
raising plow and will not
retract.

Check the pressure and
return line routing.

Pressure line MUST be
connected from P on pump
to P on valve manifold.
Return line MUST be
connected from R on pump
to T on valve manifold.

6. Wings drift back when

extended.

Check wing return
solenoid valve on manifold
Check pressure

If solenoid valve is
contaminated, clean or
replace. If pressure relief
valve is contaminated,
clean or replace.

7. Plow lowers too fast.

Check flow control valve.

Close flow control valve to
desired drop speed.

8. Wing(s) will not extend or

extend slowly, motor
runs.

Check hydraulic fluid level. Hydraulic fluid level should

be within ¾” from top of
reservoir when lowered and
in the V-position.

Check power/ground
cables and control cable
are connected properly.

Connect.

Check wiring on valve
block for proper
connections.

Refer to the wiring diagram
