Electrical System
Theory of Operation
The snowmobile electrical system consists of a
tail / stop light, headlight, brake light switch, head
light dimmer switch, emergency stop switch,
speedometer, tachometer, key switch, and a light
regulator. A schemat ic representation of the snow-
mobile electrical system is shown in Section 4,
Electrical Lighting System .
AC current to operate the electr ical lighting com-
ponents is generated in the lighting coil on the
stat or pi ate .
The schematic shown in Figure 2-35 shows all of
the components in the lighting system .
2 -24 THEORY OF OPERATION
1. The AC current from the lighting coils is routed
through the voltage regulator which adjusts
the flow of current according to the demands
of the system . This regulator operates all the
time . If it is not operating , the tachometer and
brake light will malfunction .
2 . With the key switch in the RUN position, the
cu rrent is routed from the regulator to the key
switch, tachometer, and brake light switch.
3 . With the key switch in the RUN / LIGHTS
position, the current is routed to the instru -
ment lights, tail light, and dimmer switch .
4. The current is routed by the dimmer switch to
the appropriate head light beam or f ilament.
