f. Starter Installation
1. Position the starter (Fig. 9-41, 1) in its mounting
opening on the flywheel housing. Position the
ground cable (7) over the correct starter mounting
bolt (2). Secure the starter with three 12-point
fasteners. Torque nuts to 3.4 lb-ft (4,6 Nm) and
torque hex-head capscrews to 32 lb-ft (43 Nm).

2. Connect the red, positive (+) battery cable
(Fig. 9-41, 5) to the upper solenoid stud (4). Install
the two red wires (3) to the upper solenoid stud, and
secure with lockwasher and nut.
3. Connect the blue/orange wire (Fig. 9-41, 6) to the
solenoid mounting stud.
4. Connect the negative (–) battery cable to the negative
battery terminal (Fig. 9-42, 1).

9.11 CHARGING CIRCUIT
The purpose of the charging circuit is to maintain battery
voltage between 13.8 and 14.2 volts. The key switch
must be in the RUN position with the engine running in
order for the charging system to operate.
The charging circuit consists of the battery and a belt-
driven alternator with an internal voltage regulator. These
components work together to provide electrical power for
the vehicle, including the starting system, operator’s
instrument cluster, horn, solenoids, back-up alarm and all
accessories.
Current flows from the positive post of the battery to the
battery terminal on the starter motor solenoid.
When the ignition key switch is in the RUN position,
current flows from the instrument cluster to the alternator
D+ terminal, and is used to excite the field windings; The
alternator begins emitting a charge. Current flows from
the alternator B+ terminal to the starter motor B terminal,
then through the positive (+) battery cable to the battery.
The circuit in the instrument panel connects to the battery
positive terminal through the fuse panel and detects field
voltages in excess of 16 volts or system voltages that are
less than 2-4 volts below battery voltage. Either of these
conditions will cause the warning light on the operator’s
instrument cluster to illuminate.
The alternator charging warning indicator (Fig. 9-43, 1),
a battery-shaped icon on the instrument cluster panel,
illuminates for three seconds when the engine is started
and will remain illuminated if the engine is not running.
The alternator charging warning indicator illuminates
when the battery is at a low state of charge, and when the
alternator is no longer able to charge the battery.
