ACCESSORIES INSTALLATION
On all electric start models : The direct current
(DC) utilizes the snowmobile frame as ground
“wire” while all alternating current (AC) consum-
ers (lights, heated grips, fuel gauge, etc.) utilize a
separate ground wire.
Never interconnect AC and DC grounds as an AC
voltage drop will result. When installing accesso-
ries on
any snowmobile, connect their wires di-
rectly to the both YELLOW lighting coil wires.
Even if manual start models have an AC ground
to the chassis (on voltage regulator), all accesso-
ries utilize a ground wire isolated from chassis.
When an electric starter kit is installed, the voltage
regulator and its ground wire are replaced by a
voltage rectifier/regulator unit permitting a com-
pletely isolated AC circuit.

WARNING
Never secure electrical wires/cables with fuel
lines. Keep wires away from any rotating,
moving, heating, vibrating or sharp edge.
Use proper fastening devices as required.
