I have 77 Granada that wont stay running. I have replaced the Battery, battery cables, starter,siliniod,altenator, and voltage regulator. you have to jump the car at the moment because battery has ran dead from trying to start. once started runs for a while and dies. The altenator light comes on sometimes. While running if you disconnect the positive batttery wire the car dies. Took the altenator back had tested thought that was it but tested fine. Please Help been fighting with this for a month now.
