The light will be on with no shore power if the batteries are connected.
The light will be on with shore power if the batteries are disconnected due to the converter powering the DC buss.

Thor coaches with a light indicator are wired the same way.
If you have not broke out a voltmeter you are not measuring voltage anywhere.

Perform the experiment I posted above before continuing to argue about how these coaches and latching relays (it's not really a switch) are wired.
I stopped draining my battery when you said I did not need to go lower than 12 vDC

I got digital reading in 3 different places

1. 12vDC socket off the House batteries it was reading 11.9vDC when shorepower was off. When I connected the shorepower the reading went to 14.2vDC

2. Onan AGS it was reading 12.3vDC when shorepower was off. When I connected the shorepower the reading went to 12.5vDC

3. Voltmeter on house batteries it was reading 12.26vDC when shorepower was off. When I connected the shorepower the reading went to 12.48vDC

Note: By the time I am typing this, I look up at the AGS and it is now reading 12.6vDC So it is rising, but I have not done anything to turn a switch on or off. I can't turn it off anyway if I have AC shore power

Of course I rarely if ever go inside the actual battery compartment, but based on always having a visual of #1 & #3 above; I assume that my batteries are always slow charging if I have AC power. Now if I crank up, I get more juice. It is like slow maintainer .2 amps vs 2 amps or something? I notice this on Onan AGS display because I always crank up to move slide or level coach.

Very curious as to your thoughts and what this may mean.
