Etr Solenoid (Gr3200-D) - Toro Greensmaster 3200 Service Manual

ETR Solenoid (GR 3200–D)
The ETR solenoid must be energized for the engine to
run. It is mounted on the engine block next to the injec-
tion pump and has a blue and a blue/white wire attached
to it.
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 wires from the solenoid.
2. Using a digital multimeter, ground one lead to the
engine block and connect the other to the solenoid ter-
minal.
3. The resistance should be about 11.5 ohms.
4. Connect the wire to the solenoid.
Live testing
1. Disconnect the wire from the solenoid.
Note: The solenoid may be removed from the engine
or tested in place.
2. Connect a positive (+) test lead from a 12 VDC
source to the solenoid terminal.
3. Touch a negative (–) test lead from the 12 VDC
source to the solenoid body. The plunger should retract
making an audible "click".
4. Disconnect the test leads from the solenoid.
5. Reconnect the wires to the solenoid.
