6 volt AGM battery powers a turntable motor on a platform and store bought LED pucks (like the ones for in a closet, etc). One master toggle switch, automotive type for whole circuit.
It's housed inside an old wooden display case (just the case with glass door). This project is to display my father-in-law's antique milk bottles at the shows he attends.
To charge the battery, I have wired in a 6 volt wall wart to an XLR cable, which is to plug into the XLR jack and charge it conveniently at home in between shows but he's not tech savvy at all, so I would ideally like the display circuit to shut off while it's plugged into to charge, whether the master toggle switch is open or closed, so that the display circuit can't run off the wall wart.
My understanding is that ride on scooters use these jacks to charge scooter batteries and it somehow has a bypass in it so the scooter motor couldn't possibly run away on the user while it's charging. I have tried various configurations of grounding the XLR cable shield to the negative wire, not grounding it, while running a dummy load to see if the charging cable being plugged in would somehow safely force the motor in this experiment to shut off, but I can't make it work.
Does anyone have any idea how the scooter companies are accomplishing this? Their XLR jack replacements come with only two wires off them for charging then that connects to the speed controller box, with no further schematic provided. Would it have to be using a comparator or flip flop or something, to deactivate the scooter circuit as soon as the XLR cable is plugged in?
