constant brake light
So i installed the rear turn signal re locators on my 07 night train so i could put the wifes sissy bar on, i followed the directions to the point that came with them and never touched the brake/rear lights, but after I reconnected everything my brake light is on constantly, checked all the contact in the harness on the rear with a ohm/power reader and everything has power, but the brake light just stays constant. any ideas help suggestions are appreciated thanks.

that didnt work, i dont see how i could have gotten a wire crossed because i didnt get into the wiring harness of taillight/ brakelight, im starting to think if maybe the switches in the levers are maybe stuck

Have you tried checking your brake light switch? I had to replace mine just three weeks ago because it got stuck at the ON position. On regular style tail light this is bad because it causes the light bulb to overheat and the socket to start melting. When I went to H-D to get a new one, they told me it was a pretty common problem. It is easy to test if this is the case. Follow your rear break line back from the master cylinder. Along the way you will find a bend in the line with a pressure switch in it. It is a silver fitting with two black wires plugged to the end of it. Gently but firmly pull one of the wires off (it is a spade type connection). Turn your bike on and see if your tail light is still on. If it is not then that is probably the problem. Verify this by testing both your break levers. You should see your brake light come on when you apply the front break but not when you apply the back.
You can operate the bike with this switch unplugged until you can replace it. You will just need to make sure you brake with front at all times (I sometimes only use my rear brake if I just need to decelerate some).
Let me know what you find out. If it is the brake switch I can give you advice on replacing it.

I was having this exact same problem. It turned out to the front brake switch. It appeared that the right lever may have bumped into something and got part of the housing tweaked. I carefully tapped it back into position, and works perfectly now.
