Full Version: 12v master switch

I have noticed that the interior lights are much brighter if I turn on the 12v master switch on the entry door panel.  We are plugged in on shore power.  I am not sure if this correct or if I need to check something out.  Any help?  Thank you.
When that switch is OFF in my coach I have no low volt lighting at all.
Same here on our coach.
Same here, switching the master to off kills all the 12v lights inside.

I figured that was what it does but when switched off it does not kill the 12v lights.  Will need to find out what is going on.
Something is feeding back into the circuit when the master is off. Out of curiosity when you unplug the coach does the lights go out?
I've not traced it yet, but when I turn 12v master off (which kills all interior lighting excrpt the door activatedlight in entry) I can hear what sounds kinda like a circuit breaker click. Sounds like it could be in R5 aquahot bay, but as stated I haven't looked.

On same topic, has anyone installed a second master switch, possibly bedside?
