Thanks ropesandfenders. I have contacted them to see if it`s compatible. Will let you know outcome.

Got put onto Apuljack Engineering. Sent unit to them, they invented and built a brand new battery charger unit and fixed the breakers. When fixed I took caravan to their premises and they fitted it back into the caravan and did all the checks. Had to drive from Norwich to Weston Super Mare but well worth it for peace of mind. Top service, nice and helpful staff and all work guarunteed. Thank you.
