Default Brake light

I have a 92 Fatboy, the taillight burned out so i replaced it and noticed the brake light wasnt working either, when engaging rear brake theres nothing and when engaging the front the tail light blinks, im sure its a loose wire, does anyone have the link for wiring diagrams?? Thanks

I didnt know there was a switch by the lower frame, where exactly would it be located? I have had the tanks & seat off, i had sum issues with the turn signals, had to pretty much rewire them, and at that time everything worked fine,

There are 2 switches, 1 in the bar perch throttle side, the other is on or near the rear master cylinder.
Follow the rear brake line, you'll find it. But regardless the bulb shouldn't blink unless you've added a strobe module. But that's getting ahead of ourselves.
Dos the front brake handle light the bulb every time, even just to blink?
Does the rear brake not light it at all?

Electrician here too.
Is the blinking a pattern or eratic?
Listen for sizzling under the seat.
Theres a plug under the seat in front of the battery.

Both switch wires meet at the plug then go to the brake light.
Check there for a break or corrosion. If the brake light’s flickering the wire is more than likely intact from the plug to the light.

Don’t screw with the front switch unless you have to.
Check everything else first
