Fuse box, Suzuki Boulevard C50 2005

Question edited for clarity.
Question moved to model category.

The problem with a Trike is that the wiring will be custom. For the brake light, check the switch with a multimeter for continuity. For the lights look for a break in the wiring. There may also be a relay involved in the running lights.

fuse box located bottom casing left hand side take the top side panel off with key then take bottom case off with allen key fuses to the right off radiator reservoir

Chances are it's the same as on the C50, Two main fuses under the seat by the battery and the others are behind the rear chrome cover on the left side of the bike. You'll need Allen keys to take the panel off and the lid of the fuse box should contain a list of which fuse does what.

fuse box either under seat or one of the side covers. your issue could be a fuse. can you jump starter with cables to verify starter works?

under the seat near the battery

its not the fuse, change the bulb.

The main fuse (30 amp) is under the saddle. The system fuses are found behind the left side crankcase cover along with the coolant reservior.

I'm thinking it's either the ignition switch or a fuse.
Try replacing the fuses first...it's easier.
If it's not the fuses feel free to post again and we'll work on the switch,or try alternate ideas.

Yea I have a 06 c50 boulevard. Pull your seat off and below it will be the battery and a few fuses. I can't remember for sure 2 or 3 fuses, check to see if there blown. When I had that problem it was a blown fuse. Cheap fix if you know where the fuses are.
