Fuel Stop Solenoid - Toro Reelmaster 5200-D Service Manual

Fuel Stop Solenoid

The solenoid must be energized for the engine to run. It
is mounted on the engine block near the injection pump.
In Place Testing
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
from from the measured value of the component you are
testing.
1. Disconnect the connector from the solenoid.
2. Using a digital multimeter, touch one lead to the pin
of the black wire and the other lead to the pin of the
white wire. The resistance of the pull coil should be
about 0.33 ohms.
3. Using a digital multimeter, touch one lead to the pin
of the black wire and the other lead to the pin of the red
wire. The resistance of the hold coil should be about
12.2 ohms.
4. Connect solenoid to the wiring harness.
Live testing
1. Disconnect connector from the solenoid.
Note: The solenoid may be removed from the engine
or tested in place.
2. If the solenoid is removed from the engine, make
sure that the solenoid plunger moves freely and is free
of dirt, debris, and corrosion.
3. Connect a positive (+) test lead from a 12 VDC
source to the pins of the red and white wires.
4. Touch a negative (-) test lead from the 12 VDC
source to the pin of the black wire. The solenoid should
engage making an audible "click".
5. Remove positive (+) voltage from the pin of the white
wire. The solenoid should stay engaged.
6. Remove positive (+) voltage from the pin of the red
wire. The solenoid should release.
7. Reconnect the wires to the solenoid.
