Mirrors: Description and Operation

Each of the Outside Mirror have two reversible motors: one to adjust the mirror view up and down and 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 to the DOWN position, battery voltage from circuit 1732 is applied to circuit 1499 and the Up-Down Motor in the LH Outside Mirror. The LH Outside Mirror Up-Down switch supplies a path to ground through circuit 88, the DOWN position contacts of the Up-Down switch and circuit 150. The LH Mirror Up-Down motor runs to turn the mirror up.

If the Mirror Control Switch is pushed to the UP position, the same motor receives voltage and circuit 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 circuit 1499 gets battery voltage and circuit 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.
