I have a 94 dyna wide glide, tail light and turn signals work but no brake light with either front or rear switch activated, bulb is good

 

Ok i'll be the one to ask, did you try a new bulb. Being you didn't say.

 

Sometimes bulbs will appear to be intact despite being blown. I'd try a new bulb. If that don't work, get a sm with a wiring diagram, test power at the bulb, and work your way back until you find power and the cause of the failure. You clearly have a good ground if the turn signal works. You are talking about the bullet style tail lights right?
