ELECTRIC STARTER AND CHARGE 11-7
Positive Brush-to-Yoke Resistance
If resistance
is less than infinite, positive brush
is horted to ground. Replace entire positive
brush ass’y
(C).
BRUSH HOLDER CHECK
(Bendix-Type only)
Set multimeter selector switch to R x 1
position and measure resistance between
brush holder (A) and
its base (B).
Positive Brush Holder-to-Ground Resistance )
If resistance is less than infinite, replace brush
holder.
PINION CLUTCH INSPECTION
Rotate pinion manually.
While rotating pinion in direction of normal
operation, smoothly reverse the direction of
rotation to confirm that
it locks.
If any irregularity is noted, pinion clutch
should be replaced.
STARTER MOTOR REASSEMBLY
Reassembly is the reverse order of disassembly.
Note the following points.
Apply multi-purpose
glease to:
Sliding surface of pinion and shaft’s spline.
Dust
seal lip.
Metal holding shaft
at front and rear cover.
Do not reuse retaining ring on shaft, which
was removed.
Removal weaken and deform the retaining
ring.
Charging System
A charging system produces the current required
to maintain the battery in good
state of charge.
The charging system consist of
a flywheel
magnet, charging coil (stater) and regulator.
The charging coil output current
is rectified
(changed from AC to DC) and
is maintained
constant voltage for battery charging.
Rated speed of AC generator
is 3,350 rpm, and
at lower speeds available output will be re-
duced relatively.
CHARGING SYSTEM CHECK
Be sure to perform more basic checks first such as;
1.
2.
3.
4.
5.
Battery defective or not charged.
Eroded or
loose terminals or connections.
Cracked insulation or brocken wires.
Wire grounding out the system.
Defective switch.
Condition Found (Battery Run Down)
Check battery polarity. Negative
(-) side of
battery should be grounded to engine or frame
(equipment), positive
(+) side of battery to
regurator charge lead.
