it does not fully charge the neddle is all the ways to the left, if i turn anything like the lights heater, the voltage really drops even more? i have replaced the alternator and voltage with factory ones and it makes no differance... all fuses are good and i pulled them out one at a time and still no differance? now if i take the battery leads of and check theres almost 14v but if i turn anything on the car wants to die?
