    Hi there,
    The battery on my 00 toyota corolla carvan (1.9 diesel) is over charging.
    The battery light is on in the dash, and the battery is now releasing gas everytime I drive.

    I thought that it was the alternator and sent this to the auto electric shop to be reconditioned but the problem still persists.

    Anyone any ideas at all?
    thanks for reading

    The alternator was over charging the battery so it probably cooked it. Can you get a lend of a battery to try it out. I'd say its the battery.

    fully charges New battery in. Dash battery warning light still on :(

    Checked the volts again 14.4 normal car running
    14.2 under load (lights etc.)

    Dont know if i should risk driving the car and chance frying this new battery too.

    Are all the wires on the alternator solidly connected? Signal cable to the dash could be broken / not connected properly

    I took the car out this evening for a good long spin with the new battery fitted and it doesnt seem to be overheating.

    The dash light may well be a separate issue. I will check for loose connections in the morning. I shall keep you posted!

    Thanks for all the replies.

    Find a decent auto spark, and give them the whole car not just the alternator.

    14.4 volt is perfect, old battery is probably perfect too, stop wasting money and bring car to an auto electrician
