Need help with 98 century brake lights.

I have a 98 century and I noticed that my running lights for the brakes on the tractor are not working. The brakes lights illuminate when I press the brake pedal. I'm thinking it's a fuse. So my questions is where is the fuse located is it the one under the dash on the passenger side or is it located somewhere else? If it's not a fuse then what? Anyone ever had problem like this? If yes how did u fix it?

 

If there is no power that means bad fuse? Right?

 

Thanks for the response. That was actually the problem a broken wire. I found it a day or so after I started this post. It was on the back of the frame not too far from the lights. Easy fix.
