Can someone help trouble shoot my problem? I have a 1975 Dart and I just recently took it to the shop and I paid them to install a whole new audio system (Radio, wiring, and stereos in the back) It took 2 days to do it. The first day they ran out of time and the radio i was going to buy they said was defective and to come back tomorrow and they would hook up another one. 2nd day i goto their shop and when I go to move my car around the car wouldn't start because the battery was dead. And keep in mind that i recently charged my battery a week before because a couple of time i left my head lights on, which is why I recharged the battery in the first place. And so they hooked everything up and on my way back home my car turned off b/c of the dead battery. I called my dad to jump my car and he looked at the alternator dial on the dashboard and he told me that the needle is either supposed to be center line or above center line Positive and if the needle is in the
negative side then the battery is being drained fast.What should I do? Get a new alternator, battery, or is it the wiring? Or could it just be that my car can't handle the new car system?
