Went for a ride today on my C109R, I blew my horn twice and the entire speedo console shut down, no speedo, no indicator lights, no gas gage, no turn siginals
no tail or break lights. I still have the headlight. I checked the five or six fuses in the battery compartment, all okay. Is there another fuse bank on
this bike anywhere, or what else could it be oh yeah and no horn either.

Damn, I've no idea. I'd try replacing fuses anyways, you can't always tell by looking. Sounds like a short in the horn circuit, might want to explore that with the millimeter.

Multimeter, not millimeter.

If the rest of the bike is working fine, I'd try putting a new 10A fuse in the #4 position, and seeing what happens.

Your horn is on the same circuit as your signal lights and speedo. You definitely blew a fuse, make sure to check again.
Unless you burnt a wire in the circuit, it should be the fuse.

Sounds like you hooked up an air horn without a relay?
You need a relay circuit for larger horns.

Also , don't put a larger horn in the place of the stock. Its possible to damage the radiator fins with the vibrating.....and it rubbing. Be extra careful.
