ELECTRICALSYSTEM

The motor-generator (IZ-volt, negative ground) will function as a cranking motor when the ignition key is turned to the "START" position, driving the engine by means of abelt.

When the engine is operating, the unit will function as a generator.

and Replacing the Motor-Generator Belt

Replace the motor-generator belt when it becomes badly worn. To remove the old belt,

loosen the motor-generator brace bolt I'A" and

mounting bolt.s lIB", Illust.17. Move the gener- ator in toward the engine and slip the old belt

off the pulleys and over the crankshaft. Install the new belt in the reverse order of removal and adjust the belt to the proper tension.

MOTOR-GENERATORBELT

Check the tension of the motor -generator belt after the first 10 hours of operation and

every 50 hours of operation thereafter. The tension is correct when the belt can be deflected a maximum of 1/4-inch by a ten pound force applied midway between the two

pulleys.

Also follow this procedure when a new beltis installed.

Adjusting the Motor-Generator Belt

Loosen the motor-generator brace bolt I'A'I and mounting bolts IIBI', Illust.17.

Move the generator away from the engine

until the tension on the belt is correct. See

Illust. 16.

Note: Under no circumstances should a pry

bar.be used on the motor-generator to obtain belt tension as damage to the bearings will re suIt.

VOLTAGE REGULATOR

A satisfactory generator charging rate is

maintained by the voltage regulator. If the

regulator fails to operate correctly, see your

International Harvester dealer.

Hote: Never place a jumper lead between,

or accidentally bridge, the I'BAT'I terminal

and the I'FI'terminal on the regulator, as this will damage the regulator.

LIGHTS

The headlights are sealed-beam lights. The

parts are so constructed that the filament, re- flector, and lens are all assembled in a unit

permanently sealed against dirt, moisture,

and corrosion. If a filament burns out or a lens bxeaks, the complete unit must be re- placed. Refer to I'SPECIFICA TIONS".

TAilliGHT

To replace the taillight lamp, remove thelens from the taillight and replace the taillight

lamp with a 4 candle power lamp. Refer to

"SPECIFICATIONS".

FUSE (Electric Lighting)

It is important to use the same capacity fuse for replacement. Refer to "Specifica- tions". If the lights fail. check the fuse. If a fuse continually burns out. check the electri- cal wiring for short circuits.

The fuse is located in a fuse housing in theline at the back of the instrument panel. See

Illust. 18.

To install a new fuse. pre ss in on the fusehousing

cap and turn counterclockwise to re-move it from the fuse housing. Remove the oldfuse

and replace it with a new one. Then re- assemble the cap to the housing. Remove the battery if necessary to reach the fuse.
