G'day all

I have just fitted a Redarc isolator to my vehicle, to allow charging of the deep cycle battery in the new van, via Anderson plug.

When I put the multi meter on my cranking battery, I got 12.42 volts (engine not running). At the terminals of the Anderson plug, there was a reading of zero.

I started the car, still nothing at the Anderson plug, let it idle for a minute or so, then I get a reading of 13.88 volts at the plug. I am assuming that this is how the isolator works..... top up the cranking battery, then allow flow to the second battery. Am I correct?

I would sooner ask a 'dumb' question than visit a tourist attraction for, say, 6 hrs, and come back to a flat cranking battery!

Thanks for any info

Cheers, Dave
