2-Pulse and 6 Pulse Alternators

The difference between a 2 pulse and 6 pulse alternator system is the number of AC sine waves created by the
alternator in one revolution of the crankshaft. For example, on a 6 pulse system, the alternator will create 6 pulses,
or 6 complete AC sine waves, in one crankshaft revolution. The tachometer reads these sine waves, therefore
giving you accurate RPM readings. Refer to the following text for applications.

Tachometers:

Tachometers for snowmobiles will have an identification marking on the back side. For example: The tachometer
for a 600 RMK will have "6 pulse" (or 6P) written on it.

2002 Flywheels

The flywheels used on model year 2002 snowmobiles will not work correctly if used on earlier build models. The
2002 flywheel is calibrated specifically for 2002 CDI boxes and will not fit on earlier snowmobiles if installed on
earlier snowmobiles the flywheel may cause CDI failure. The 2002 flywheel will be stamped with two red dots
and "14 ONLY", this means that this flywheel will only work with 14 degree CDI boxes. These flywheels were used
on the 2001 440 Pro X and the 2001 700 XC SP with Exhaust Valves.
