Need a little help!
I just got done putting on my new trees and I was going over everything and I noticed that my back brake light don't light. I had to splice the switch wires to run them through the trees and bars, I have done this before with no problems. I tested all the lights, headlight high and low, blinkers both left and right and 4 ways, front brake brake light, horn, kill switch and the start switch and everything works just fine. But for some unknown reason when I press the back brake I get no light! Anybody have any ideas what's wrong or do I need to take it to the dealer?
Thanks so much for any input!!

RE: Need a little help!
If the brake light worked before you started........you have a short someplace maybe a pinched wire or your splice is wrong. Did you make a diagram of the wires before you cut them? Do you have a schematic or electrical service manual?

RE: Need a little help!
I did draw a diagram and all the wires are correct and matched to each color, If I had a short wouldn't at least one of my switches not work, remember it's only the rear brake light, everything else works fine and there's no blown fuses, It starts, runs great too. I would think if I had a short it would blow a fuse and one of my switches wouldn't work... I will double check my wiring again tomorrow but It all looked good to me.

Do you have a test light ?
if so trace the wires to the tail light before and after every connection ,
good luck /

get the test light. double check ground... it is the most important item in DC. you could have a poor splice ie cold solder or it came apart after you heat shrinked. You did heat shrink right? or taped it right?

Could it really be the bulb? I mean the brake light works when I use the front brake.

Use test light on the power coming in to rear brake light switch. and then out of the switch.
If you have no power coming in, then start testing back towards the power source.
No power out, could be bad switch, or adjustment.
If you have power out, at the rear switch itself, then test everything towards the brake light itself.

RE: Need a little help!
If I take the 2 wires off the back brake light switch and touch them together.... woooo wooooo the light comes on..... guess that means the switch is bad!
