LIGHT SWITCH
The light switch is n'lounted on the instrument
panel which is located under the engine hood
and is attached to the front fan bracket. The
light sw-:'::h incorporates the generator con-
trol, which is of the two step system, having
a high and low charging rate. The fuse for
the lighting system is also mounted on the
light switch.
A
fuse of either a
10
or
15
amp.
capacity can be used. The operation of the
light switch isas follows: When the switch
is all the way in, the lights are off and the
generator charge rate is at the low P?sition.
With the light switch pulled out to the fi
nt
stop the lights are on and the charging rate
is in the high position. With the light switch
pulled all of the way out, the lights are off and
the charging rate of the generator is in the
maximum position. This manuell control of
the charging rate is accomplished by a resis-
tance unit on the outside of the light switch
