Can someone help a rookie out with a silly problem. 1999 FXDL, I´m trying to get the battery out to change it. I´ve got the seat off, but can´t find the trick to getting the battery box open. It´s on the side infront of the ignition. There´s a box with a cover on it, the cover seems loose but doesn´t come out. I´m guessing something is still holding it, but I sure can´t find anything.
