DESCRIPTION

This circuit is the power source circuit for the meter. This circuit provides two types of power sources; one is a constant power source, and the other is an IG power source. If a voltage of 12 V is not applied to terminal IG2 when the power switch is turned on (IG), the indicators will not operate.
