Troubleshooting Guide

Prior to diagnosing your Power Plow, verify that all connectors (cylindrical connector, plastic electric connectors, ground
and power wire terminals, coil wire lead and extension harnesses) are free of corrosion and are well lubricated with
white lithium grease. Insuring that all connectors are in good working order will save time in determining your snowplow
attachment's service needs.
Problem
Plow functions will not work after all connect-
ions are made or plow functions are slow.
Plow functions start and terminate suddenly.
Multiple valves, excluding the DS cartridge Diode pack may be corroded or damaged.
valve, function simultaneously. (Note: DS valve
will energize with every plow function.)
Plow functions are reversed. (i.e. Driver's side
wing extends when passenger's side wing is
activated from the control.)
Skid steer pump relief noise can be heard.
Plow movement is broken or will not move. in the wrong ports.
Plow angles only one way.
Wing will not stay angled when plowing.
Plow will not stay angled when plowing.
42 Troubleshooting Guide (1 of 2)
Probable Cause(s)
No power to the DS cartridge valve (Note: DS cartridge valve
opens hydraulic fluid flow to manifold for every function.).
DS cartridge valve is receiving power.
Solenoid cartridge valve may be contaminated or damaged.
A bent cartridge will not allow the valve to move freely
inside of the cartridge.
Extension wire harness (16' or 24') may be installed wrong.
Skid steer hydraulic fluid flow is set to variable flow.
Wire harness may be damaged.
Hydraulic hoses are connected wrong. (Note: Manifold
stamping may be reversed. Review guide under A-frame
cover for proper hose port numbering.)
3/4" hydraulic pressure (P) and tank (T) hoses are installed
Skid steer computer conflicts with cylindrical connection.
The wing pressure relief valve is set too low. NOTE:
Increasing the pressure relief valve will cause damage to
your plow. Do not set the pressure relief greater than
900 PSI.
The angle pressure relief valve is set too low. NOTE:
Increasing the pressure relief valve will cause damage
to your plow. Do not set the pressure relief greater than
3000 PSI.
Suggested Remedy
Verify DS cartridge valve is connected properly. Diagnose
the wire harness. Review wire harness schematics. If
power is present, review the next step.
Verify that the DS coil is magnetizing. Position a screw-
driver inside of the coil. When the respective function is
activated, the screwdriver is drawn to the side of the
coil. If the solenoid is not drawn to the screwdriver,
replace the coil. If power is present, review the next step.
Determine a damaged cartridge valve by reversing the
driver's side and passenger's side cartridge valves.
Replace valve if necessary.
Review the wire harness schematic(s) for proper connect-
ion. Harness connectors may simply be reversed.
For plow functions to work, the skid steer hydraulic fluid
flow should be set to continuous flow. Review your skid
steer operation manual for proper flow settings.
Clean diode pack thoroughly and/or replace.
Verify harness is not damaged. Review wire schematic(s)
to troubleshoot connection(s). Replace if needed.
Review the Sequencing Valve & Hose Identification
Guide under the A-frame cover for proper port locations.
Review the assembly diagrams on pages 14 and 32 for
proper hose installation. (Note: The "Tank" hose contains
a 90˚ swivel fitting and installs on the top port labeled "T".)
Using a jumper wire, connect pin K to pin L at the back
of the cylindrical connector.
Test the wing pressure relief. Attach a T-fitting with a
fluid PSI gauge to the base end of the wing cylinder.
Pressure relief should not be greater than 900 PSI.
Review the illustration on page 43 to increase the
pressure relief settings.
Follow the guidelines indicated above; however, the PSI
setting should not exceed 3000 PSI. NOTE: If the plow
is floating back when angled to the right, adjust the left
pressure relief valve and vice versa.
