There should have been no direct connections of the alarm into the charging circuit. The only way to check the alternater is to use an alternater tester (preferably on a test bench to rule out a wiring problem in the car). Before going that route first check all of the connections on the alternater, battery, frame, ground straps etc. Make sure the belt is not slipping and the battery is good. As far as the car going dead make sure that the door switches shut the lights off when the door is closed. If you keep the interior courtesy lights off all of the time the only lights that go on are the 3 in the doors. Without the interior lights on you don't know if the lights are really going off when the doors are closed. There are supposed to be little rubber caps on the ends of the door switches, when the are worn or missing the switches don't shut the lights off. You can get by with a short piece of vacuum hose slipped over the end or just pull the wires off and see what happens. Many owners install a master switch which wil help.
