Turn adjustment screw (4) counterclockwise to
lower the voltage setting. Turn adjustment
screw (4) clockwise to raise the voltage setting.
Put 3S6252 Rubber Sealant on adjustment

Socket (5/16"-%" drive). 3. 1P2977 Tool Group.
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.
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
