    Hi Guys

    Got a big problem. Was driving the car today and the stereo went off, looked down and switched it back on and when i looked back up the red battery light was on. Then i noticed that when i accelerate the traction control light would come on along with the yellow brake symbol. Then a gear symbol with an i in the middle came on next to the "D" symbol in the gearbox screen.

    Only drove the car a few yards and parked the car up. It drove fine and all seemed well.

    Had the AA guy come down who tested the battery and said that when I revved the car it was showing over 18 volts but on idle it was on 14 volts ................ WTF?

    He said the alternator was over charging and as a result it was sending too much current to the car. Now I am happy to get the alternator replaced which should be done tomorrow but i'm baffled as to why all these other lights have come on. The traction control and yellow brake light only come on when i accelerate as does the gearbox symbol but when the car is idling the lights go off but the gearbox symbol stays on.

    Is the car flucked or will it be ok when the alternator is changed.

    I'm getting married on sunday and this is one bit of stress I could do without.

    Some electrical componets shut down should the battery voltage excede a set level, this is simply to protect them. Im sure once the alternator problem is fixed that all your warning lights will be ok again.
