Suggested Remedy
Turn clockwise 1/16 of a turn and test. NOTE: Never make
adjustments when the plow is in the raised position! Fluid
pressure will make the valve difficult to adjust and serious
injury or death can occur from a falling plow.
Verify the green/yellow (G/Y) wires for the ground are
connected. Verify black/white (BK/W) wire for the power is
connected. If both are connected properly, replace the
headlight relay(s).
