Took it to the dealer today and they said the battery was kaput, I bought it from them about a month ago so they replaced it for free. They also found a broken/clogged pressure valve in the right rear that was causing moisture in the battery area, they said this might be causing my drain. The alt checked out OK.

Replacing the valve parts and labor was $395, I hope this solves the problem, but does not seem like a definite cause. Any thoughts?
