Hydraulic Valve Solenoids
These solenoids can be tested using the “Output
Checks” feature of the ACE Diagnostic tool.

The solenoids can also be tested manually.
Note:
Prior to taking small resistance readings with a
digital multimeter, short the test leads together. The me-
ter will display a small resistance value (usually 0.5
ohms or less). This resistance is due to the internal re-
sistance of the meter and test leads. Subtract this value
fromthe measured value ofthecomponent you aretest-
ing.

ohms.
B. The resistance for a 28 watt coil should be about

Install new solenoid if necessary.
A. Make sure o-ring is installed at each end of the
coil. Apply ”Loctite 242” or equivalent to threads on
end of valve stem before installing nut.

B. Tighten nut to a torque of 2 - 5 ft-lb (2.7 - 6.8 Nm).
Over-tightening may damage the solenoid or cause
the valve to malfunction.
Hydraulic Valve Solenoid Functions
The list below identifies and describes the function of
each valve solenoid on the hydraulic manifold. Each so-
lenoid functions when energized.
Note: Each electrical harness connection for the valve
solenoids has a colored power wire and black ground
wire attached to it.
