Hydraulic Lockout Solenoid Valve.
427-C1825
(1)
Hydraulic lockout solenoid valve is an implement ECM output. Solenoid valve will disable pilot hydrau-
lics in failure mode and enable pilot hydraulics when energized by current from implement ECM.
(2)
Solenoid valve has a connector with two contacts. One contact receives power from implement ECM con-
nector contact J2-2, while one joints with other solenoid valves and returns to implement ECM connector
contact J2-4. Pin J1-47 supplies power to pin J2-2 within implement ECM. If input to J1-47 does not have
battery voltage, then solenoid valve will not be energized.
