Charging System
5P300 Electrical Tester. Make reference to Special Instruction Form No. GEG02276, and to the instructions inside of the cover of the tester, when testing with the 5P300 Electrical Tester.The condition of charge in the battery at each regular inspection will show if the charging system operates correctly. An adjustment is necessary when the battery is constantly in a low condition of charge or a large amount of water is needed (more than one ounce of water per cell per week or per every 50 service hours).Make a test of the charging unit and voltage regulator on the engine, when possible, using wiring and components that are a permanent part of the system. Off-engine (bench) testing will give a test of the charging unit and voltage regulator operation. This testing will give an indication of needed repair. After repairs are made, again make a test to give proof that the units are repaired to their original condition of operation.Before the start of on-engine testing, the charging system and battery must be checked as shown in the Steps that follow:1. Battery must be at least 75% (1.240 Sp. Gr.) fully charged and held tightly in place. The battery holder must not put too much stress on the battery.2. Cables between the battery, starter and engine ground must be the correct size. Wires and cables must be free of corrosion and have cable support clamps to prevent stress on battery connections (terminals).3. Leads, junctions, switches and panel instruments that have direct relation to the charging circuit must give correct circuit control.4. Inspect the drive components for the charging unit to be sure they are free of grease and oil and have the ability to operate the charging unit.Alternator Regulator Adjustment
When an alternator is charging the battery too much or not enough, an adjustment can be made to the charging rate of the alternator.To make an adjustment to the voltage output on these alternators, remove the voltage adjustment cap (1) from the alternator, turn the cap 90°, and install it again into the alternator. The voltage adjustment cap has four positions: HI, LO, and two positions between the high and the low setting.

Tighten nut that holds the pulley to a torque of 75 5 lb. ft. (100 7 N m) with the tools shown.
ALTERNATOR PULLEY INSTALLATION
1. 8S1588 Adapter (1/2" female to 3/8" male). 2. 8S1590 Socket (5/16" with 3/8" drive). 3. 1P2977 Tool Group. 8H8555 Socket (15/16" with 1/2" drive) not shown.Starting System
5P300 Electrical Tester. Make reference to Special Instruction Form No. GEG02276, and to the instructions inside of the cover of the tester, when the 5P300 Electrical Tester is used.Use a D.C. Voltmeter to find starting system components which do not function.Move the start 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.If the solenoid for the starter
