Please help me identify a part.

Hi, I'm new here.

I have a 1981 XJ650 that I just picked up in a trade -- the second XJ650 I've had in my life, though I don't remember much about the first other than the fact it was a pain in the butt (the previous owner didn't take very good care of it). I'm a bit mystified by this:



What is that part? For reference, it's between the bottom of the fuel tank and the top of the engine, toward the front. Here's the side of the motorcycle:



That part is hanging in the area just below and behind the reflector glowing in my camera flash.

Nothing jumping out at me, but more experienced folks will likely know what that's for. Can you tell if something isn't working? That's probably a good indicator.

 

Turn signals don't work -- they don't turn on at all. I thought it might be missing a flasher relay, but I plugged a new three-prong up-to-12.8v flasher relay into that part and it made no difference. Unless it needs a flasher relay plugged into it and there's something else wrong with my turn signals (all fuses and bulbs look fine; the switch is an open question right now), that doesn't seem to be it.

 

Turn signal relay socket.

Unless it was an original Yamaha relay, there is no 3 prong relay that will work. The Yamaha relay is proprietary and is really a two-prong flasher with the third prong being for the auto-cancel function. They are available used (they are repairable if you get a bad one), or you can us a two-prong no-load relay, or make your own two-realy system to reatin the self canceling feature.

Okay, thanks. I wasn't aware the plug was three-prong but for decidedly non-standard reasons. I suppose this means my guess that the dangling plug I found is, indeed, where the flasher relay goes, and the reason it didn't work is simply the fact that it's a very weird relay. I'd appreciate it if someone could just explicitly say "Yes, that's for the flasher relay!" or something to that effect.

Will a standard two-prong relay work if I don't care about the self-cancel feature? That seems to be what you're saying. I don't want to waste money buying a relay that will never work, after all.

 

I believe k-moe did say "Turn signal relay socket".

 

Umm... I did.

Did you read the link that I provided?
The information you requested lies therein. Specifics about a two-pin relay are on the first page.

 

Sorry, I missed it, orphaned above where you quoted what I said. My attention went directly to where you provided more information.

Not yet. I'll do that now.

 

the brown and brown white wire are the wires you can hook a 2 prong flasher unit to but you would need to make jumper wires because the wires are on opposite sides of the connector not in an L configuration

the brown wire comes from the fuse the brown white wire (supply) goes to the directional switch(load)

so with 2 quick disconnects and the blade style that will go into the connector you can make jumpers if the connectors will fit onto the flasher you may have to trim the flasher blades

best if you just find a used one on ebay or buy a new one

Not if you get the right flasher. The one I last used on an XJ650 was a direct plug and play.

 

I've got a working flasher relay for it. Now I just need to fix the switch (yes, it turns out the switch is bad, too; I can jump the wires with a screw to get the flasher to work, but the soldering on the wires had broken loose). Thanks for the help identifying the socket and pointing to more information.
