So I was coming home from a camping trip in which everything seem to work fine. I flipped my fridge to low volt (I have three settings gas /120/ low volt) to drive home thinking that it would remain charged while plugged into my car. when I arrived home my trailer would not lift and my water pump would not work. I checked the fuses all were good then I thought my battery might be dead. I checked that it read at 12 volts, but this clicking was going on down in my hydraulic box, but I can't isolate exactly were the clicking is coming from but it is definately electrical because the next morning my battery was dead. thanks for all the help
