yea something isnt right... Just those few things shouldnt draw that kind of power. If you dont start your car for a few days will the battery go dead?

Ok, the ground on the block had no space after the swap so I bolted it to the cyl head, the belt isnt tight due to the tensioner and alt difference, it stays charged but then this happened in the rain.

How tight is the belt? Can you move it easy? The tensioner should be in about the center of it'* travel. If it'* near the end of it'* travel then it will be loose and water on the belt will make it slip, could be at the harmonic balancer or at the alternator.
