Mystery wire?? Where does it go?

[1978GS750E]

OK, the person that dis-assembled the bike, me, did not label this wire and now has no idea where it goes. It's off of a 1978 GS750E. It's 11" long from eye to eye. Anyone know where it goes?

Most likely a ground wire. The terminal size would suggest a battery ground but the wire gauge looks small for that.

EDIT: looks like a turn signal ground wire...

Not sure exactly, but that is a ground. You should have a battery to frame ground and an engine to frame ground. If you're missing either of those, then that would be my choice.

It's definitely a ground. I just posted almost an identical question with nearly identical wire in mind.
My wire is B/W with a bullet connector in the middle and two ring terminals on either end. I know I have an engine to battery ground, and an engine to fuse ground. I don't think I have an engine to frame ground.

As for solid black wires with two ring terminals, the only ones I found today were turn signal wires. Let us know if you find the missing spot. :-)

looks like the wire that goes from starter relay solenoid and negative battery.

If you ever need to know where factory wiring goes look st thd factory manual cable routing.

I think I found it! looks to be a ground that goes from the negative battery terminal to the center rectifier ground ???

[dwilson0725]

Center rectifier ground? I don't follow, can you elaborate?

[1978GS750E]

I believe it goes from the center ground bolt on the rectifier to the negative battery terminal.

So it's THE ground for the RR? I thought that was hardwired. Guess I've never looked that closely.
