Please Help with 1985 Mustang GT Cobra 5.0

I have had my car for years and its my love! I have a little problem..while driving the headlights will dim and stereo will shut off sometimes. Also, I seem to kill batteries constantly..new batteries are drained and killed! Does anybody have any idea what the problem might be?

Any information you have about 1985 Mustangs just to share would be appreciated and well used! I love my LITRE!!

Thanks guys!!

Did you check the alternator?

Im assuming your alternater is charging,since that is the most obvious reason for your complaints, there may be a short in your electrical system, it could be headlites,dome or something of that nature.check your alt to see how many volts you have when engine is idling,should be about 14 volts.do this by simply connecting a volt meter to battery. if you dont have a good charge check belt tension.if you do then you have short,something is draining your battery. you will have to systematically check each circuit for a fault.if you think your close you can remove fuse from fuse box for that circuit.to nail an electrical gremlin is tough even for pros,good luck.
