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 con-
trol.
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 HI/LOW range control m anifold (item 4 in Figure 51)
includes a solenoid valve with an integral solenoid c oil.
Testing of all of these c oils can be done with the coil re-
maining on the hydraulic valve.
NOTE: To assist in troubleshooting, identical solenoid
coils can be exchanged. If the problem follows the ex-
changed 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).
