Storm L4-1600cc 1.6L SOHC (1990)
Radiator Cooling Fan Motor: Description and Operation
With the engine running, the generator applies voltage to the restart relay. The voltage passes through the closed contacts of the restart relay to the
condenser fan relay and the radiator fan relay. The triple switch closes when the refrigerant pressure is above 214 psi. When the triple switch closes, the
condenser fan and radiator fan relays energize.
The condenser fan receives battery voltage from fuse E-4 through the closed contacts of the condenser fan relay. The radiator fan receives battery
voltage from fusible link FL-4 through the radiator fan relay.
The thermo switch closes when the coolant temperature is above 179°F. When the thermo switch closes, the radiator fan and condenser fan operate in
the same manner as when the triple switch closes.
When the ignition switch is turned to START, the restart relay is energized, the contacts are opened and the fans will not operate.
