ELECTRICAL SYSTEM
MOTOR-GENERATOR BELT -Continued
VOLTAGE REGULATOR
A satisfactory generator charging rate is maintained
by the voltage regulator. If the regulator fails to
operate correctly, see your I nternational Harvesterdealer.
Adjusting the Motor-Generator Belt
Loosen the motor-generator brace bolt and mount-
ing bolts.
NOTE: Never place a jumper lead between, or
accidentally bridge, the "BAT" terminal and the
"F" terminal on the regulator, as this will damage
the regu lator.
Move the generator away from the engine until the
tension on the belt is correct.
NOTE: Under no circumstances should a pry bar
be used on the motor-generator to obtain belt
tension as damage to the bearings will result.
LIGHTS
Tighten mounting bolts and brace bolt.
Lights are optional on all models except the
Models 149 and 169.

The fuse is located in a fuse housing in the line at
the back of the instrument panel.
To install a new fuse, press in on the fuse housing
cap and turn counterclockwise to remove it from
the fuse housing. Remove the old fuse and replace
it with a new one. Then reassemble the cap to the
housing. Remove the fuel tank if necessary to
reach the fuse.
Replace the motor-generator belt when it becomes
badly worn. To remove the old belt, loosen the
motor-generator brace bolt and mounting bolts.
Move the generator in toward the engine and slip
the old belt off the pulleys and over the crank-
shaft. I nstall the new belt in the reverse order of
removal and adjust the belt to the proper tension.
Before working on any part of the electrical
system, disconnect the battery ground cable at the
battery negative (-) terminal. Do not reconnect
this cable until all work has been completed. This
will prevent shorting and damage to any of the
electrical units. Examine the electrical cables occa-
sionally to be sure they are not being frayed by
contact with adjacent parts.
NOTE: If tractor is equil
drive belt must also be
generator belt.
