I have a 2003 1500 Nomad. In the last week when I go to start it the battery sounds like it's dead. Engine turns over very slowly or not at all. When I put the tester on the battery it test 12V (12.3V) and when I run the bike (after boosting it) it test 13.6V, so it seems to be charging. I have taking the battery out and cleaned the posts, charged it over night and it worked fine for about a day. The battery seems to be holding it's charge also.

I'm hoping someone out there knows how to fix this because I have no idea. If you've seem or heard of this before please let me know how to fix it.

Thanks,
