* Test charging after the battery is charged is performed by an alternate
square wave signal that outputs IC404/pin 100 (Battery Power circuit).
Battery Charging comes from Q001 (not shown)
If battery charging is called for, IC404/pin 100 goes high to charge the
battery. The High turns on Q004 and bi-directional Q001 to connect the
DC In and Battery positive terminals as described in the Battery Power
section of this book. Charging ends when the batterys microprocessor
informs IC404 to stop charging.
Battery Charge Inhibit
Q005 is normally OFF (not active) with or without a battery. If the car
battery cable is connected, Q005 turns ON to ground out the one-second
pulses into Q003. This grounds the battery test charge signal and there-
fore the battery from charging.
The Amber Battery Charge Light Turns ON (not shown)
If charging is called for, the one-second pulses from IC404/pin 27 stop
and the amber charge light is lit. The charge light circuit is not shown.
