Each of the outside mirrors has 2 reversible motors. The
motors perform the following functions:
• | One motor adjusts the view up and down. |
• | One motor adjusts the view left and right. |
The driver operates 4 switches. These switches control the polarity
of the voltage to the motors. The mirror select switch directs these control
voltages to the following outside mirrors:
• | The left outside mirror |
• | The right outside mirror |
When the switches are in the positions shown in the schematic, the left
outside mirror moves. When you move the Up-Down switch to the DOWN position,
the following actions occur:
- Battery voltage from CKT 1040 is applied to
the following components:
• | The up-down motor in the left outside mirror |
- The left outside mirror up-down switch supplies a path to ground
through the following components:
• | The DOWN position contacts of the up-down switch |
- The left mirror up-down motor runs. This turns the mirror up.
If you push the mirror control switch to the UP position, the above
process repeats, with the following differences:
• | The same motor receives voltage. |
• | The motor runs in order to turn the mirror down. |
The left left-right motor operates in a similar manner when you move
the left-right joystick to the LEFT position. CKT 1499 receives battery
voltage and CKT 81 is grounded through the left-right switch.
The left left-right motor operates in a similar manner when you move
the left-right joystick to the RIGHT position. CKT 1499 receives battery
voltage and CKT 81 is grounded through the left-right switch.
