Answer
Mark-

  It sounds like the battery is either grounded where it's not supposed to be, or you've got a short somewhere.  Like my profile says, I'm not an electrical wiz, so I really can't tell you where to start other than making sure both of the cables are securely connected to their respective points.  Other than that it's just going to take some detective work to find the broken link.  Hope this helps.
