On my 2019 JL- Can anyone tell me if the Cig Socket runs off the main or aux battery when the Jeep is off? I suspect it runs off the aux battery but want to know for sure. We are getting ready for a camping / off-roading trip to Ouray CO so I'm testing out the new camping fridge. With the Jeep off, the fridge went into low voltage cutoff almost immediately (was around 10.5v). I checked the the main battery and it read 12.4v at the terminals. I have the HD Electrical package with the 700Amp battery. Please share your experiences if you have used a fridge plugged into this socket.
