Run Solenoid (Groundsmaster 328–D) (Solenoid With 3 Wire Connector)
The run (ETR) solenoid must be energized for the en-
gine to run. The solenoid is mounted on the engine block
near the injection pump.
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”.
In Place Testing
5. Remove positive (+) voltage from the pin of the white
wire. The solenoid should stay engaged.
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.
6. Remove positive (+) voltage from the pin of the red/
black wire. The solenoid should release.
7.
Reconnect the wires to the solenoid.

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.

Using a digital multimeter, touch one lead to the pin
of the black wire and the other lead to the pin of the red/
black wire. The resistance of the hold coil should be
about 12.2 ohms.

Live testing
1.
Disconnect the wire harness connector from the so-
lenoid.
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/black and white wires.

Lawn and Garden readers have rated Toro 92801SL Rev I Groundsmaster 300 Series Groundsmaster 328 D Service Manual 5.0 out of 5.0 based on 2 product reviews. Need 328D. Manual pdf. Will rate after finding manual
t has been a very reliable machine but getting parts is hard and not cheap to buy , generic parts has been cost effective and reliable , i am unable to get a wiring circut diagram for this unit as most problems are electrical problems
