Valve Block Solenoids - Toro Reelmaster 6500–D Service Manual

Valve Block Solenoids

1. Disconnect the wire connector.
2. Connect a 12 volt battery so the positive (+) battery
terminal is connected to colored solenoid lead. Connect
the negative (–) battery terminal to black lead. The valve
spool should retract completely as 12 V.D.C. is applied
between leads.
3. If valve spool does not retract check for binding or
damage in valve.
4. If valve operates smoothly, but does not retract when
12 V.D.C. is applied to solenoid leads, replace solenoid
coil.
5. If valve still does not retract after replacing solenoid
coil, replace the valve.
NOTE: To do a quick test without removing solenoid
valve, hold a screwdriver to top of affected valve. When
solenoid is energized, screw driver should be attracted
to valve stem, due to magnetism from energized sole-
noid. This test will not identify a sticking valve spool.
Solenoid coil resistance:
20 Watt solenoid:
28 Watt solenoid:
