I bought this car a few months back off ebay and in all this time i've had to charge the battery overnite every nite!! Ive had 3 alternators and 2 batteries and its still not charging. When its first started its charging at 14.5v with my meter on the battery, 4 or 5 mins later its charging at only 11.5/12v and if i go for a drive the battery will eventually die! The battery charge light on the dash will not even illuminate to tell you its not charging! Can someone help and tell me why its not charging please?
