I put a new battery in my car along with a new alternator and voltage regulator (original style). Immideatly the battery began to spray acid all over the engine compartment, so I replaced the voltage regulator with an electric one I had laying around. That stopped the battery from over charging but now the alternator guage doesn't work. I don't think the battery is holding much of a charge so I will soon replace it. Any idea what could be wrong? Also, as I mentioned in a different thread, the car seems to idle really bad now.
