A power management system for a snowmobile is provided to efficiently manage power supplied to a cooling fan and to a heater on the snowmobile. Th e power management system can be incorporated into a control unit of the snowmobile and can be comprise of a fan motor control section for activating the fan motor by supplying electric pow er from a generator (or a battery). The fan motor control section operates the fan motor in various operating conditions in accordance with the value detected by a temperature sensor associated with a fluid cooling system of the snowmobile's engine. The power management system can also include a heat control section for controlling the electric power supplied by the generator (or a battery) to the heater by adjusting it in accordance with such parameters as maximum power levels associated wit h preset temperature settings or variable temperature settings, an engine speed sensor signal, an d the operating condition of the fan motor.
