About a month ago, I was driving on the motorway when my alternator light came on. Then the ABS, and airbag and some other light. Then about 15 mins, they all went out. Took it to a vauxhall dealer, had a full service, and apparently nothing wrong with the alternator. Two days ago, the alternator light came on and off. Then the stereo just went off. Stopped the car, and couldn't restart it until about a dozen attempts later. Got it running onto the motorway when all the electrics suddenly died. The recovery reckoned its the alternator. I'm inclined to agree. Are we correct? The battery's also brand new. If it is the alternator, how much is it to replace at the garage? I've managed to find a new one online for 55 quid, and probably cheaper on ebay. Thanks
