This  is a common fault with these power supplys when they get a power surge .you can buy the power board but may be more than you paid for the whole unit.

just keep searching for "12v charger" and only look at auctions, then sort them by ending soonest

 got a 30amp smart charger, with 3 independent 10amp channels so it can charge 3 batteries separately without joining them together

I'm going to connect 1 to the engine battery (10amp charge) and 2 to the house batteries (20amp charge) :-)

RM I am looking forward to the BBB hope I can make it

I have a bad hip at the moment and it is giving me some stick
Something to do with IT band syndrome and inflamed bursitis

I will just have to Waite and see if the physio can get me sorted out in time
