I'm not sure if the battery is located in the same place on an 05. I have a 95 and it's on the upper left hand side half under the seat.
Mine has a chrome box so;
1. loosen up the chrome strap that keeps the crome lid on. It's a long stud on the strap and its on the rear end of the box hanging down. Feel around and you will find it. Either use an open-end, box, or deep socket to get it loose. If you have a ratcheting box wrench that's the easiest.
2. Remove the strap, lid, and and the outer "box". It's only 3-sided. The battery is now exposed.
3. Tilt the battery towards you about 20 dgrees.. (to the left of the bike) That's the only way to get to the nuts to loosen the cables on the posts.
4. The posts are on the right side of the battery, or on the "inside" from you. Remove the
Black negative cable FIRST! If the positive should touch any metal on the bike while the negative is connnected you can cause serious shorts/zaps/blow-up the battery etc.
5. Remove the
RED positive cable.
6. Tilt and lift the battery out.
7. To Re-install reverse this procedure including hook up and tighten the
RED positive cable first!
Hope this helps.
