CLOCK - Power Source Circuit

DESCRIPTION

This circuit is the power source for the clock assembly. This circuit provides two types of power sources; one is a constant power source mainly used as a backup power source, and the other is a power source mainly used for signal transmission. The constant power source is mainly used as a backup power source of the clock assembly, however, it is also used for communication.

HINT:

If the clock assembly displays "1:00" when the ignition switch turned off, and turned to the ON position again, the B terminal has a malfunction.
