Starter Solenoid - Toro Greensmaster 3150 Service Manual

Starter Solenoid

The starter solenoid used on the Greensmaster 3150 al-
lows current flow from the battery to the engine starter
motor when energized. The starter solenoid is attached
to the rear frame in front of the battery (Fig. 21).
Testing
1. Park machine on a level surface. Make sure the en-
gine and ignition switch are OFF.
2. Disconnect negative (black) cable from battery and
then disconnect positive (red) cable (see Battery Ser-
vice in the Service and Repairs section of this chapter).
3. Note wire locations on starter solenoid for assembly
purposes. Disconnect cables and wire harness connec-
tors from solenoid.
NOTE: Prior to taking small resistance readings with a
digital multimeter, short the meter test leads together.
The meter will display a small resistance value (usually
0.5 ohms or less). This resistance is due to the internal
resistance of the meter and test leads. Subtract this val-
ue from the measured value of the component you are
testing.
4. Apply 12 VDC directly across the solenoid coil posts.
The solenoid should click as the solenoid coil is ener-
gized. Make sure resistance across the main contact
posts is less than 1 ohm.
5. Remove voltage from solenoid coil posts. The sole-
noid should click as the solenoid coil is de--energized.
Make sure resistance across the main contact posts is
infinite ohms.
6. When testing is complete, secure cables and wire
harness connections to solenoid. Torque nuts on sole-
noid coil posts from 15 to 20 in- -lb (1.7 to 2.3 N- -m) and
nuts on main contact posts from 50 to 60 in- -lb (5.7 to
6.8 N- -m).
