Troubleshooting Guide - Blizzard Power Plow 810SS Assembly & Operation Manual

Troubleshooting Guide

Prior to diagnosing your Power Plow, verify that all connectors (rubber connectors, plastic electric connectors,
ground and power wire terminals, coil wire 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 function simultaneously.
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.
Wing will not move.

Troubleshooting Guide (1 0f 2)
Probable Cause(s)
Solenoid cartridge valve may be contaminated or damaged.
A bent cartridge will not allow the valve to move freely
inside of the cartridge.
Skid steer hydraulic fluid flow is set to variable flow.
Diode pack may be corroded or damaged.
Wire harness may be damaged.
Hydraulic hoses are connected wrong.
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
1500 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.
Control station, wire harness or cables may be loose or
improperly connected.
No power to the cartridge valve.
Coils are receiving power.
Suggested Remedy
Determine a damaged cartridge valve by reversing the
driver's side and passenger's side cartridge valves.
Replace valve if necessary.
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 19 and 20 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 (cylindrical connector only).
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 1500 PSI.
Review the illustration on page 33 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.
Verify control station, wire harness and all cables are
securely connected. Clean if necessary.
Verify S1 & S2 coils (passenger's side slide box
retract and extend) and S9 & S10 (driver's side slide
box retract and extend) are connected properly.
Diagnose the wire harness. Review all wire harness
schematics. If power is present, review the next step.
Verify that the coils are 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 coil is not drawn to the screwdriver, replace the
coil. If power is present, review the next step.
