brake light not engaging

[reorx911]

Hello,
1982 750e here. Purchase bike recently, knowing brake light doesnt work. The lights themselves are fine, but the front brake lever doesnt click on light depression like it should when the relay is tapped. Lever is a bit loose and had been replace, wondering if maybe it was installed incorrectly or if i need to run a new relay. Any thoughts would be much appreciated.
thanks

Open up the relay switch and take a look. Mine was slightly corroded so it wasn't making contact. Cleaned it up and it works fine. It's very simple.

Did the tiny spring make it back in place on the switch? I lost mine (never even saw it shoot out) when I first tried to adjust my switch and it took a long time to figure out what had happened.

Right off BassCliff's site:

If cleaning alone does not work, the switch is available from CRC2 for about $10 + S/H. Even with S/H, it's still cheaper than you're going to get it anywhere else I think. Some have instead gone with a pressure switch which replaces the banjo bolt on the master cylinder. Z1 Enterprises sells those.

Hi,

Partsnmore.com has them for $6.

Look at the bottom of the page. A lot of members like the pressure switches rather than the mechanical ones.


Thank you for your indulgence,

Well that's pretty good, right there. Alas the min order at PnM is $35, plus flat shipping. But if you have some other stuff to buy there that's a really good price

The OEM kits seem to go around $20.

Parts Shark has the contact for $ 2.22. I got two just to have a spare on hand. Once you clean up the switch and contacts and put some dielectric grease on it from the dreaded PO neglect you probably will not have to do it again.

Look on e-bay... there's a guy on there who sells new aftermarket ones for around $8.

I've used a few of them, they work fine.
