OPERATION



The thermal electric switch is located inside the air cleaner to sense the incoming air temperature and indicate a cold weather start-up condition to the MCU when the air temperature is below 50°F (10°C). Above 65°F (18°C), the switch opens to indicate a normal engine start-up condition to the MCU.
