It's interesting that you suggest this -- I actually purchased a used Hitachi alternator (60 amp) from a friend who had removed it from his engine in place of a Balmar. I have it sitting in my shop, but haven't decided whether to install it. I'm still debating installing an aftermarket alt (actually, what I'm really doing is trying to find a good deal on a Balmar external regulator).

Thanks for the suggestion!
