    Doh! Stupidly connected battery terminals the wrong way round!

    Hi all,

    Mk3 1998 R - Reg Polo 1.0 formerly belonging to the ex. She doesn't want it. Has been sitting outside the house for a good few months, battery completely flat. Decided to charge up the battery and try and fire it up.

    In a moment of pure idiocy, I've attempted to connect the battery terminals the wrong way round. Realised almost instantaneously and disconnected and reconnected the right way round, but now there's nothing, no life at all. I connected the battery back to the charger and it's gone straight into maintenance mode, so I assume the battery is good (it was quite new if I recall).

    What damage have I likely done, and what should I be checking first?

    Thanks

    First posts normally go in introductions else you could get a free fix and we never see you again!!!

    Are you mechanically minded if you connected the battery leads the wrong way around? The can damage the alternator and other electronics..

    You need to get the battery checked out.

    ECU, ABS, air bag, dash, immobiliser, radio, central locking pump.... all are likely toast and even fixing one will be more than the cars is worth.

    Vile Invention

    Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.
