9.6 ENGINE START CIRCUIT
9.6.1 Starter
The starter (1) is located on the left side of the engine.
a. Testing the Starter on the Engine
If the starter does not engage when the ignition key
switch is turned, check the following:
1. The main fuse may be blown, requiring replacement.
Check for the cause of the blown fuse.
2. There may be a defect in the ignition key switch,
ignition wiring or starter solenoid.
3. Check battery condition. Clean the battery posts and
the connectors at each end of the battery cables.
4. Check for broken wiring and damaged insulation on
the wiring. Replace all broken or damaged wiring.
5. Check all connections at the starter solenoid, key
switch and wiring harness plugs. Clean and tighten
all connections.
6. If the starter still does not operate after these checks
have been performed, check the starting circuit.
b. Starter Circuit Checks
1. Check wires and connections for looseness,
corrosion, damage, etc.
2. If a “whirring” noise is heard but engine does not turn
over, starter is spinning but not engaging flywheel.
Starter drive or solenoid that pushes drive forward to
engage flywheel may be defective. Missing or
damaged teeth on flywheel can also prevent starter
from cranking engine.
3. If starter only “clicks” it may indicate that battery is
discharged, or that there is a loose or corroded
battery cable connection. Check battery state of
charge and battery condition first, then check cables
and cable connections.
4. For additional information on the starting circuit, refer
to Section 9.5, “Electrical System Schematics.”
c. Starter Removal
Remove the starter only if it fails. To remove the starter:
1. Place a Do Not Operate Tag on both the ignition key
switch and the steering wheel, stating that the
machine should not be operated.
2. Open the rear and side engine covers. Allow the
system fluids to cool.
3. Properly disconnect the battery.
4. Remove wires from solenoid stud. Remove positive
(+) battery cable from starter. Label and disconnect
wire from starter solenoid housing stud. Record how
wires are installed to ensure correct installation later.
5. Loosen, but DO NOT remove, fasteners securing
starter to flywheel housing. Support starter securely,
as it is relatively heavy and will fall if not supported.
