5.
Put 3S6252 Rubber Sealant on adjustment
screw (4) and install cover (3) and end plate (2).
CAUTION: Make certain that the field wire (5) is not
located over the transistor pins (6). The pins can make a
hole in the insulation of the wire.

STARTING SYSTEM
Tools Needed:
5P300 Electrical Tester.
Use a D. C. Voltmeter to find starting system
components which do not function.
Move the starting control switch to activate starter
solenoid. Starter solenoid operation can be heard as the
pinion of the starter motor is engaged with the ring gear
on the engine flywheel. The solenoid operation also
closes the electric circuit the motor. Connect one lead of
the voltmeter the solenoid connection (terminal) that is
fastened to the motor. Put the other lead to a good
ground Activate the starter solenoid and look at the
meter. A reading of battery voltage show problem is in
the motor. The motor must moved for further testing.
No reading on the meter shows that the solenoid
contacts d close. This is an indication of the need for to
the solenoid or an adjustment to be made starter.
If the solenoid for the starting motor will not operate,
it is possible that the current from the
battery is not getting to the solenoid. Fasten one lead of
the voltmeter to the connection (terminal) for the battery
cable on the solenoid. Put the lead to a good ground.
No voltmeter reading shows there is a broken circuit
from the battery. Further testing is necessary when there
is a reading on the voltmeter.
Further test by fastening one voltmeter lead to the
connection (terminal) for the small wire solenoid and the
other lead to the ground. Look at the voltmeter and
activate the starter solenoid voltmeter reading shows that
the problem is solenoid. No voltmeter reading shows
that problem is in the starter switch or wiring. Fasten
one lead of the voltmeter to the battery wire connection
of the starter switch and put the lead to a good ground.
A voltmeter reading indicates a failure in the switch.
A starting motor that operates too slow can have an
overload because of too much friction in the engine
being started. Slow operation of the starting motor can
also be caused by shorts, loose connections, and/or dirt
in the motor.
Pinion Clearance Adjustment
(Delco-Remy)
Whenever the solenoid is installed, make an adjustment
of the pinion clearance. The adjustment can be made
with the starting motor removed.
CONNECTION FOR CHECKING PINION CLEARANCE
1. Connector from MOTOR terminal on solenoid to
motor. 2. SW terminal. 3. Ground terminal.
1.
Install the solenoid without connector (1) from
the MOTOR connection (terminal) on solenoid
to the motor.
2.
Connect a battery, of the same voltage solenoid,
to the terminal (2), "SW".
3.
Connect the other side of battery to ground
terminal (3).
