GROUNDSMASTER 4500−D SHOWN
Numerous hydraulic solenoid valve coils are used on the hydraulic control
manifolds of Groundsmaster 4500−D and 4700−D machines. When energized
by the TEC controller, these coils provide hydraulic circuit control.
Three (3) different solenoid valve coils are used on your Groundsmaster. Two
(2) of these coils slide onto the solenoid valve and are secured with a nut.
Additionally, the two speed shift manifold (item 4 in
solenoid valve with an integral solenoid coil. Testing of all of these coils can be
done with the coil remaining on the hydraulic valve.
Note: To assist in troubleshooting, identical solenoid coils can be exchanged. If
the problem follows the exchanged coil, a problem with the coil likely exists. If
the problem remains unchanged, something other than the solenoid coil is the
problem source (e.g. switch, circuit wiring, hydraulic problem).
