Hi all, ive had to change my battery on my gte 8v astra, problem being is that the car wouldnt start unless it was jump started.
The battery was at 9v in the red of the voltmeter reading and wouldnt start the car.
Having changed it the car starts perfectly and was wondering that the voltmeter now shows 12v before firing up and whilst traveling it rises 3/4 but doesnt get maximun 15v. Is this correct or could the altanator not chargin it properly.??
any help appreciated
