Starter Solenoid - Toro Sand Pro 5040 Service Manual

Starter Solenoid

The engine starter solenoid is attached to a bracket
above the battery. When energized, the starter solenoid
allows current flow from the battery to the engine starter
motor.
Testing
1. Park machine on a level surface, lower attachment,
stop engine, apply parking brake and remove key from
ignition switch.
2. Tilt operator seat up to gain access to starter sole-
noid.
3. Disconnect negative battery cable from battery and
then disconnect positive battery cable.
4. Disconnect wires from starter solenoid (Fig. 8).
5. Apply 12 VDC directly across the solenoid coil posts
(Fig. 9). The solenoid should click as it is energized.
While energized, resistance across the main contact
posts should be less than 1 ohm (continuity).
6. Remove voltage from solenoid coil posts. The sole-
noid should click as it de–energizes. Make sure resist-
ance across the main contact posts is infinite ohms (no
continuity).
7. Replace starter solenoid if necessary.
8. Reconnect wires to starter solenoid. Torque nuts on
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).
9. Connect positive battery cable to battery first and
then attach negative battery cable.
10.Lower operator seat.
