Jack, You said the battery goes dead after a while, The battery light should go out unless the alternator regulator has been harmed. Be sure only the brown/yellow wire is the only wire hooked to the alternator regulator. You may show a charge, but it really isn't. John hervey http://www.specialtauto.com/alternators.shtml << I had an alarm removed last spring. Since then the battery light has remained on all the time. The car seems to be charging alright, the gauges show the system charging. The battery does run dead after a long time sitting (I do have a cd changer and aftermarket radio that do take some power), I don't remember if it did it before the removal though. >>
