Happy,
Lots of stuff on the FJR will have full voltage applied constantly, and those things get activated by connecting those items to ground. The horn and brake lights are done that way, so maybe other stuff as well. If something should be working and it does not, check to see if the ground wires have voltage on them. If so, the ground wiring is not well-connected and will need attention. Connect the ground lead of the multimeter directly to the battery negative terminal, of course, not to a frame member or some random bolt. If you have a Battery Tender SAE connection, one side of that plug is connected straight to the battery negative terminal.
