Nine of the ten hydraulic functions require
energizing the electric motor and opening solenoid
cartridge valves. The LOWER function does not
energize the motor but requires the opening of
one cartridge valve.
Power from the vehicle battery is supplied to the
solenoid coils and the motor relay via the plow
module. The solenoid cartridge valves operate in
various combinations, directed by the cab control,
to send hydraulic fl uid to the snowplow lift and
angle rams or back to the reservoir. (Power is
supplied to the plow module via the battery cable
and motor relay connection.)
