I have a '99 FXSTC. I had it running back in April so I could get it inspected. Got busy and it has been sitting since with the battery maintainer connected to it. Tried to start it today and on the first hit it just tapped the starter and then everything went dim. The battery seems to be fully charged, but when I press the starter button it will drop in half. It almost appears the battery may have a short. It is just over five years old. I am also thinking that maybe the maintainer may have done it in. Any ideas will be greatly appreciated.
