I did a thread about this I think a year ago. I ended up opening it up and greasing the contacts on the hi/lo switch and that seemed to fix my issue.

Well, the issue has come up again. But this time it includes the “flash” button.

Out of curiosity does anyone have a schematic to the light switch, or just a dimenstration on how the light switch works? I was thinking of taking it apart again and putting dielectric grease where needed.

Also, a side question. How difficult is it to simply swap the switch assembly? I see a small square computer style going from the switch into the bike underneath the brake fluid reservoir. Does that simply unplug, or am I looking at an annoying job where the switch wire has to be routed all the way down the frame of the bike?
Here’s a photo I couldn’t upload due to file size so here’s some random third party think of the photo.

Does the switch simply plug into this black square?



I believe I’m having these issues because I ride 365 rain, sleet, or snow. Albeit no snow in Florida.
I believe this is the part number, and anyone able to verify?

The first thing you need to tell us is that you have a 2017 EX

That is the correct part number for the left hand switch on a 2017, but I would check other plug in connections, where that switch plugs into the harness, and the connector to the the headlight itself. Both are inside the headlight shell.

Yeah, I do that.

I would start with just cleaning the contacts inside the switches again.

Not that these are "old bikes by any means but its common in "older" bikes to have to clean the contacts in the controls/switches dur to moisture and such. I would probably avoid dielectric grease also i would just make sure they're clean/light sanding of the surface to have bare metal and you should be good for awhile

Any other recommendations? I’m in a rural area no one has that, except guitar center which is the next city over.

I see it on Amazon may just get it on there.

I did exactly that.

Open the switch up sprayed all the contacts, and working fine.

I see some sort “powder” inside the switch. The first time I opened it I thought maybe sand from the Florida wind/air, but it almost looks like calcium or battery acid.

It’s a very small amount. Don’t think it’s battery acid as it didn’t burn my skin, though I didn’t touch it directly some just fell on me when I opened the switch up.

Whatever it is I think this is what makes the switch “stick”, or delay.

Good deal
