    Hi papa that's one way, but I am fairly confidant that it will work, its the power supply which is a problem. There used to be a battery combiner gizmo, you could use it in a 12v system with 2 batteries to get 24v, but I can't find it now.

    Brian you can borrow my glasses. :Rofl1: Plenty of 24v to 12v, but nowt the other way.

    Assuming that both your domestic and engine batteries are 12 volt and they DONT share a common earth, then an earth from one and the positive from the other with a bridging link from the other earth to the other positive will give you 24 volts, But its bloody risky. lots of checking first.

    there are some listed on ebay but vary in price from around £30 to £70 for a 5 or 10 amp jobby

    10amp converter

    5amp converter

    both from china though

    many cheaper (£8 > £9) but only 3.75amp.
