Load test the battery. Is it dead? If so, recharge it and check the alternator. Sounds like the alternator stopped working and the engine was running on just the battery. When the battery died the engine stopped. Hope that helps! Jim

Yeah; your battery has just enough juice left to energize that door ajar dinger. That's about half a volt..... I agree that your alternator is likely dead or dying, and that's starved the battery. Get the battery charged up so you can drive a mile or so to a mechanic. He'll test the battery and charging system. It might just be corroded battery cables, or something relatively minor, but in a car this old, you shouldn't take any chances. It's a 95% chance you're going to need a new alternator and battery.
