This has me a little confused.
Here is a snippet of my avionics wiring drawing showing the TCW IBBS backup battery.
What does the Switch labeled "Stby Bat Master" on pin 1 do?
The power comes in through a 5A breaker on pin 5, so opening the switch doesn't seem to kill the juice going into the battery. The juice leaving the battery is hot all the time (it seems).
Is there internal circuits to control the power input by opening or closing the switch??
