These are readings off your car battery aren't they? Or is this a reading off a second battery in the car? What I'd be interested to know is how well/quickly it charges up a nearly dead battery in the camper/second battery. Out of interest, have you got any pics of how/where you mounted your second battery?

From what the Red Arc rep says, with the standard SBI12 isolator in, it will take twice as long to charge the trailer, because it won't recognise that it needs charge, and the variable voltage alternator won't crank up. I'm no expert, I'm just listening to people who are supposed to know what they are talking about. But sure, they are trying to sell me something. It's working. FYI, I'm running a 80Lt dual zone Waeco in my trailer while I'm on the go.
