    Hi

    We dont have a 5th wheeler but we're on holiday in Spain and a guys just arrived on the site with an issue with his rig. I asked if he's a funster but isnt, shared the site URL with him :BigGrin: but said I'd ask the question on his behalf.

    He says he dropped a spanner in the fuse box last night in the dark and shorted out the 12V. Here on the campsite while connected to 240V everything is working ok, but as soon as he goes back on the road he doesnt have 12V. He's checked all the fuses/breakers etc but everything looks fine.

    Its a long shot (he says he US rigs are different wiring) but does anyone have any pointer to help?

    Thanks :BigGrin:

    I assume it was the 12v fuse box.

    there may be a master fuse near the battery bank or in/near the battery isolator switch.

    shorting the fuse box should only weld the spanner between a live and earth, which would blow the master fuse, and as everything works on hookup that only leaves the master fuse....or possibly destroyed the master switch or relay...but my guess is the fuse.

    Thanks pappajohn, i went down to their pitch and told them your suggestion, we check the master fuse, there was a nice shiny gold one in there, all ok.

    He then found an fat earth wire burnt in the rear left inspection hatch, spliced it, and re-joined, everything sprung into action. The side pods are now out and he's about to have a cold beer to celebrate (he's been looking for hours for the issue).

    Cheers

    I was a bit concerned that the front (and rear) legs would not operate---also his slides------although they can be operated manually:Smile:------Unless I am mistaken the 'fridge requires 12v to operate?????
