    My cab battery stands accused of being nearly flat and is condemned to be taken to a place of disposal to be disposed of. The evidence against the accused is:

    1. It has completely discharged 5 times over winter since it came new with the van 6 years ago, so it can't be in ideal condition.

    2. The control panel above the living area door is flashing a low cab battery warning.

    3. Despite it being on permanent trickle charge from the charge-controlled solar/leisure battery circuit when in storage, the engine wouldn't turn over when I went to pick it up this weekend.

    4. The fridge will no longer run on 12v when the engine is running.

    Guilty as charged, or have I missed some vital piece of evidence that means an innocent cab battery has been wrongly accused?

    Guilty as charged ..

    however, point 4 on the evidence sheet.
    A dead engine battery doesn't account for the fridge not working on 12v while engine running... look for an accomplice by the name of fuse or relay.

    Thanks for the pointers.

    I've had a brand new cab battery fitted (which it needed anyway) but the fridge is still not working on 12v

    My friendly local MH servicing man reckons fuse/relay too and is coming to take a look at it. I shall also be mindful of the alternator possibility.

    I remember once having the battery replaced on my old VW Kombi, only to discover a few weeks later that the problem was with the coil. So it goes.
