Mirrors: Description and Operation

Each Outside Mirror has two reversible motors; one to adjust the mirror view up and down, the other to adjust the mirror view right and left. The driver operates four switches that control the polarity of the voltage to the motors. The Mirror Select Switch directs these control voltages to either the RH or LH Outside Mirror.

With the switches in the positions shown in the schematic, the LH Outside Mirror is moved. When the Up-Down Switch is moved "UP," battery voltage from CKT 340 is applied to CKT 1499 and the Up-Down Motor in the LH Outside Mirror. The LH Outside Mirror Up-Down Switch supplies a path to ground through CKT 88, the "UP" contacts of the Up-Down Switch and CKT 151. The LH Mirror Up-Down Motor runs to turn the mirror up.

If the Mirror Control Switch is pushed to the "DOWN" position, the same motor receives voltage and CKT 1499 is grounded. The motor runs in the opposite direction.

The LH Left-Right Motor operates in a similar manner when the joystick moves the Left-Right Switch to the "LEFT" position. CKT 1499 gets battery voltage and CKT 81 is grounded through the Left-Right Switch.

The RH Outside Mirror works the same way as the LH Outside Mirror when the Mirror Select Switch is moved to the "RH" position and the joystick is operated.
