  Is there power to

the motor solenoid?

    (White Wire)

  Is there power

Is the Touchpad

plugged in completely

Are "C" Valve

O-Rings in good

   condition?

Replace

  Piston

            Weld

1-1/2" x 1-1/2" x 1/2"

spacers to the A-Frame 

             stops.

Replace

O-Rings

Replace the

 P.A. Block

YES

Will the snow plow angle

right & left if not allowed

  to travel to extreme

   angled position?

YES

Does the motor run 

when angle switch

     is pushed?

NO

Replace Harness

Replace 

Touch Pad

NO

NO

Does the snow plow 

angle to the right 

the angle left 

switch is pushed?

Is the ampere draw

less than 100 amps

while trying to angle

     snow plow?

Can the snow plow be 

angled by hand when the 

P.A. Rams are disconnected 

from A-Frame?

Does the snow plow

  raise instead of

     angling left?

NO

NO

Relieve the interference

        between the 

Sector and A-Frame.

NO

Clean or replace the 

       "C" Valve.

          Retest

   Is the Pilot piston in

     good condition?

(worn/sloppy or missing)

Clean or replace the

       "B" Valve.

         Retest

Does pressure remain 

in angle hose 

when the motor 

is not running?

 

NO

NO

YES

YES

YES

NO

Temporarily put 1/2" blocks

between the Sector and

A-Frame to limit the degree 

of angle. Will the snow plow

now angle?

 Replace both the 

Coupler sets and/or

clean or replace the 

     "C" Valve.

If both hoses are stiff

inspect the Pilot Check 

Piston and "C" Valve

       for binding.
