Rear Wheel Drive Solenoid - Toro Reelmaster 4500–D Service Manual

Rear Wheel Drive Solenoid

Figure 8
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 12V DC is applied
across the 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
12V DC is applied to solenoid leads, replace solenoid
coil.
Figure 9
5. If valve still does not retract after replacing solenoid
coil, replace the valve.
NOTE: To do a quick test without removing the solenoid
coil or valve, hold a screwdriver to top of valve. When so-
lenoid is enertized, screw driver should be attracted to
valve stem, due to magnetism from energized solenoid.
This test will not identify a sticking valve spool.
