It sounds as if you have a bad alternator? Have you tried swapping it out? Maybe you could try an upgraded one (I went with a high output chrome)
The trouble with these sorts of problems is that often you replace something like the regulator, but then it is immediately damaged by the (bad) alternator, etc.......so you may want to use a new regulator too, before you turn the key.
Hope that helps
