Hi Fuzzy no wok done on the car before it started acting up. I just thought it was the case of the battery just needed renewing. So I done that, but not know I just got standard battery still had problem. RAC said it was alternator so got new one,. then still had the problem, so booked car in to auto Electric. Said I needed another alternator as the one I had was to high output 14 volts and the battery was also need as the alternator had damage the battery. So I got another alternator and second hand Calcium battery. Only to fined out that 14 volt is the normal, and a calcium battery is a must. I feel like a dog chasing its tail. But I will do as you and gcfcos have said, and see what happens. Bet after you read all this , your now thinking "wish I ha-dent asked" haha. well as all the other member that read this page. thanks to ALL for their help Paul.
