COMPONENT DESCRIPTION

Intake Door Motor
The intake door motor is installed on the intake unit. Using a link, it opens and closes the intake door.
When REC switch is ON, the ground line of the motor is switched from terminal 2 to 1. This starts the motor because the position switch contacts built into it make current flow. When REC switch is OFF, the ground line is switched from terminal 1 to 2. The contacts turn along with the motor. When they reach the non-current flow position, the motor will stop.
