Wiring question with PICs

Okay well Im still searching for my no start problem, and in doing that Ive found a wiring problem looks like a melted connector. Wondering if anyone with a manual could tell me what they go to? I did order a manual its just not here yet.(1981 GS1100G)
I have some pics there not the best but they give you an Idea

Well the pics might not work so lets see if I can describe it it looks like a nine pin connector and two of the top wires are melted they are red and white and green and white, they seem to just be jumpered together, cause theres a red and white wire on the female side of the connector that just connects loops from one hole to the next. Thanks Jordan(Newbie)

I dont have schematic for 81 GS1100, but I do have schematic for my 80 GS850. It has a connector perrty much like that, with two "jumpers", like that. The grn/wht and red/wht is in the stator circuit to the regulator/rectifyer, and that red "jumper" is in place of the headlight switch (that they had in 79). The red/org is the hot from headlight fuse and the green is to instrument lights, The yellow jumper replaces headlight switch again, yellow wire is to hi/low switch .

The connector melts like that when you get corrosion (which presents electrical resistance) between the connectors or between the connectors and the wire. Melts worse on the wires/connectors with the higher current draw, amps times resistance is heat, so the more amps the more heat. And those wires in the stator circuit are the higher amp draw circuits.

Now, what to do about it. If not completley melted-damaged, can try cleaning connectors with contact cleaner and continue to run with it, keep an eye on it to see if getting worse. But better yet, cut off the wires from the melted part of the connector (not necessarly all wires), and reconnect the wires by some other method. I see butt splices and crimp on conectors in the background of your pics. More of those will work, but I have found wire nuts (with black tape to seal out moisture) to be more reliable.

When I say I have not had good sucsess with crimpon connectors, I am refereing specifically to using them on wires that have been overheated like these. I think these overheated wires get stiff and maybe thats why the crimpon connector seem to loosen up after a while when used to replace burnt/melted connectors.

You may want to look at the other connectors in the stator circuit to the regulator/rectifyer. Those are probably in a rubber boot on the left side either behing the side panel or just foward of it (as they are on my 850). Thats where I had a problem. They are individual "bullet" connectors on seperate wires (not a multiconductor connector). Two of them will be those same two wires that are jumpered together with the red jumper in the headlight shell,..... but, ah, er, thats getting into a different discusssion, and I have yammered on enough already.

Oh, back to your original question: this probably isnt the cause of your "no start" probelm, unless its so bad that your charging system isnt keeping the battery charged (which was my problem).
 
I thought that looked like the stator connector too. Problems with connectors as stated above are all true.
