Brake light stopped working

Well started by removing rear fender. Unpluged lights/turnsignals ect... When put fender back on and pluged everything back in brake light does not work. Funny thing is that rear running light works but when depress brake lever, nothing changes. Wondering if it is electrical OR if there is a seperate bulb. Also while doing this did not put on turn signals, i do not think that would change anything with the brake light but thought I would just inform incase.

Did you try both the hand and foot brake? Might be a bad switch or a bad connection at the plug.
There are two bulbs in the tail light, but each one is tail & brake, no seperate bulb for each one (1157 bulbs).

Yes I did make sure it was both hand and foot....also the runnng light is bright enough that I could tell it was on while the sun was directly hitting it.
Two things,
1. 100% positive that brake light worked b4 I removed fender and unpluged harness.
2. Was left unpluged for about two weeks
I do not think that is enough time for corrosion to take place (but i do live in fl with salty air) plus I inspected all the terminals and they looked fine.
Any other suggestions?

Check the connection on your harness, if I remember correctly the bayonet connection can loosen up when you twist them apart. If your connections are tight use a voltmeter to check that the brake light connector has 12v when the bakes are applied.

So whats the normal voltage at running? and you say the voltage at brakes applied is 12v?

Maybe you got the running light and the brake light wires backwards. So when the light is on it is so bright that you cannot see any diff when the brake is applied.

Possible.....Here is the hook up.
1 three wire harness
1 black and yellow wire
1 red wire
The harness goes to the tail light
the other two are the power and ground to the license plate light
the wire colors on the harness are:
black and yellow (ground), red (power), and blue (i think break power).
I do not think that I can hook up the power to the backwards to the tail bc its a harness. Also the running light is not super bright but brght enough that i do not think that there is a bulb out.

oh yeah forgot there are the turn signal wires....that i did not hook up. (maybe thats the problem)
Im stumped.
How does the break switch work?

So you haven't looked at the bulbs yet? It's possible just the braking filiment burned out on both, but running light is still ok. Might even be just a loose connection at the bulbs.

Definately check the bulbs if you haven't already.

Yes that is right black yellow ground, red running lights, blue for brake light.

Both brake switches would not go out at the same time. Chances are that is not the problem. Just make sure that the connections are tight.
