wiring on a 80special

[ScottS]

I have 2 pins going in and I have 3 pins going out. I am missing the 3rd pin on the input which for the out put side is black. I had no spark untill I hooked up this wire to ground. Maybe its not supposed to go to ground? Maybe this is why my bike is not starting?

Basically Black wire not hooked up to any thing = no spark
Black wire hooked up to ground = spark

Like I said the pin and everythign was missing out of one side of this connecter. Any help is appreciated.


Sorry for the crappy pic its from my cell phone

Hey there Scott,

The wiring diagram shows 2 different black wires going to the Reg/Rect unit, and both go to ground!! The 3 white wires on the other plug are for the Alternator along with the Green one. The Yellow one goes to the main yellow line of the fuse block. The Red taps into the Main Fuse Line. Not sure why the black one isn't going to your Reg/Rect, the diagram shows them both going into it!? HTH.

I might have confused you but I am talking about the lower plug in that picture. The one with the red wire draped accross that one is my quick fix ground only a brown and green on one side with an empy pin. and a brown green black out the other

The regulators/rectifiers that I have seen on xs11's seem to be case-grounded to the frame. The smaller clip has a ground wire that just terminates at the clip (nothing out the other side).

Wouldn't be the first time the wiring diagram was incorrect. It shows the wires going to the Reg/Rect, but perhaps Clymer's considered a case ground to frame an equivalent!? However, if the bike runs when it's grounded, then perhaps there's a problem with his engine to frame ground circuit?

To elaborate on what I previously posted, I think if you get better results connecting that black to ground, the contact between the regulator and the frame where it is mounted, is oxidized.

well bike still doesn't run with it pluged in but I do get spark when I ground it

I would clean and tighten all the electrical connections and don't forget to do the same for the ground wires to the frame and engine.

Yamaha removed the redundant ground wire from the regulator sometime in 1979. What you're experiencing doesn't make sence but I have seen some pretty strange stuff in Yamaha wiring...

Glad I checked for similar issues before posting. I have a 78E and a 79SF, the rectifier quit sometime over the winter, so I scavenged the one off the 79 to get running. I went to ebay to replace the failed parts and to get some backup electrical parts to add to the toolbox for longer runs. Anyhow, my "new" rectifiers all have the the 2 wire connectors (no third black wire). the wiring diagram for the E,F and SF has the green wire go to the generator, and the black to ground, the brown appears to be power.

Anyway, I am thinking that these 2 wire (actually 7 if you include the 5 wires on the other connector) are drop in's for the 3 wires, just make sure the ground on the mounting bolt is good. What do you think Geezer and topcat?

Scott, If you want I would be happy to trade your 3 wire component for a 2 wire one if it will make you happier.

I think they dropped the extra ground wire rather early. I wouldn't worry about it.
