you can remove the seat,then undo the bolts on each side of the bracket holding the battery,then of course remove pos and negative wires,you can do it without removing the seat,just easier access

Had this same problem with my wife's 2004 XL1200C. Took it to the dealer and they discovered the batt cable was just a little loose. They tightened it and we've had no problems with that since...that was 2 yrs ago.

The brake lights get their power from the "lights" fuse.

Find the rear brake master cylinder. There's a metal line that comes out of the cylinder and goes towards the rear wheel. Follow this line and you'll come to a tee fitting with a pressure switch screwed into it. Check to make sure the wires are firmly attached to the switch. Use a test light and check for voltage to to the orange/white wire with the ignition switch in the ON position. If no voltage, you'll have to trace the wire back to it's source.

If you have voltage there, jumper across the switch with all the wires attached and see if the brake light shines. If not, you've got a problem with the wiring going back to the brake light

Good Luck
