ALTERNATOR
2. End plate.
LOCATION OF COVER
3. Cover.
ALTERNATOR REGULATOR
4. Voltage adjustment screw. 5. Field wire. 6.
Transistor pins.
1.
Remove end plate (2) and cover (3) from the
alternator.
2.
Remove the rubber sealant from the adjustment
screw (4).
3.
Use a voltmeter to measure alternator voltage
output.
4.
Turn adjustment screw (4) counterclockwise to
lower the voltage setting. Turn adjustment
screw (4) clockwise to raise the voltage setting.
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.
Alternator: Pulley Nut Tightening
(Delco-Remy)
ALTERNATOR PULLEY INSTALLATION
1. 8S1588 Adapter (1/2" female to 3/8" male). 2.
8S1590
Socket (5/16"-%" drive). 3. 1P2977 Tool Group.
OH8555
Socket (15/16"-/" drive) not shown.
Tighten nut holding the pulley to a torque of 60 to 75 lb.
ft. (80 to 100 N-m) with the tools shown.
STARTING SYSTEM
Tools Needed: 5P300 Electrical Tester.
Use a DC Voltmeter to find starting system components
which do not function.
Move the starting control switch to activate the 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 to the motor. Connect one
lead of the voltmeter to 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 voltmeter. A reading of battery voltage
shows the
