Brake light - Electrical idiot

Anyone who has worked on a bike with me knows I'm not the greatest wrench. Not the worst. But I don't understand electricity at all. So, bear with me. I used the search engine. Read a bunch of stuff. Totally confused.

Issue: tail light and brake light fine, but front brake does not activate the brake light - rear brake does

I know it could be the wiring or the switch. Basically, can someone tell me where to start using small words that you would use to explain how the internet works to a monkey? And pictures would be super helpful.

Thanks.

Switch under the brake lever on the handlebar could be bad or dirty.

When you pull the lever to you hear the subtle clicking noise?

Also check the connection to that switch. You could possibly have pulled it out maybe.

I've had that switch fail before.

Mine failed in Cody, WY. The contacts can go bad.

It is possible to disassemble the switch and clean the contacts and reassemble, but getting a new switch is the better way to go.

It's kind of odd, too, as the switch contacts are of a self-cleaning design.

Here's the part, at Partzilla: 27010-0025 SWITCH,BRAKE $18.03

Tom,
Did the F. brake light switch fail before or after the hail storm?

Paul, I think it failed between Lander and Cody. The hailstorm was up on the Top Of the World, just short of Beartooth Pass.

Had to hole up at the store for a while. This picture was taken after the hail stopped and the rain had come back. While riding up the road, visibility was about 20 feet and I barely saw the store's driveway. The man had coffee at a buck a cup and I think I left $10 with him.


I was there for about an hour before continuing on to Beartooth, but the visibility was poor.


The switch is held together by two plastic posts that are melted or glued where they poke through one side. It's possible to cut that seal and get the two halves apart and work on the switch. I did that to mine and keep it as a spare. Shoulda taken pictures.

LJ, sorry to jack your thread.

Threadjacking is always welcome.

Awesome. Thanks, guys. I got mad family stuff going on this weekend, but I'll get at this ASAP and let you know what I find. Much obliged.

OK, I do hear the click, but still not working. The connections were duly wiggled. No loose connections.

Should I assume it's the switch or is there any chance this is something that can be fixed by a duct tape and bailing wire altar to the electricity gnomes? (Thanks for the link, Tom!)

Dan,

The switch has what are known as 'wiping contacts'. As they open and close they wipe across one another, therefore they should not corrode and go bad.

But they do.

I sat in the parking lot of the Cody Best Western and dribbled gas inside the switch (it was all I had) and worked the switch on and off for a long time. No joy. I just wound up with smelly fingers to eat my pizza with.

You can verify that the switch is bad with a volt-ohm meter; they're a few bucks at RadioShack, if those exist anymore. If not, Horrid Fright carries them for hardly any scratch.

You might try squirting a proper contact cleaner into the switch and working it to see if it will come back to life. If it does, put it back in and then order a new one, install it when it comes, and carry the second as a spare. There is a single screw that holds the switch in place.

If it don't, order a new one and install it.

"Either way, you're gonna get a new switch", Tom ordered.

I'll suggest that a Lot of Plastics do not take kindly to electrical contact cleaners. Melts them or Hardens them!

WD-40 is plastic safe.

Dan,

Try this.
