Help! The alternator light is on bright with the key on, but before the engine is started. It stays on after I start the engine, but is about half bright and pulsing slightly. Then it goes off after I drive about a block. It did this last night when I left work, this morining, and again this evening. I heard a high pitch whine a couple of days ago, but it has gone away.

Is my alternator going south? Anybody else ever experience this type of failure? Is it possible it is the voltage regulator or battery?

Any advice will be greatly appreciated.

Thanks
