I was out working on Monte getting ready for another vacation... for the wife. I had the batteries out and was cleaning the front compartment. I decided to turn the Air Conditioner on as it was pretty humid outside. Turned it on and nothing happens. I was plugged in to a 30A plug that I have in my shop. I was thinking as long as I had 110V, I should be good to go on the air conditioner. Not so. You have to have a battery hooked up for the air to run. Must be something in the switch that needs 12v. Just a little info for anyone that might run into this someday...JB
