Hi FolksI'm fitting a 79ish GS1000 8V motor into my 77ish GS750. All going good with brackets made up etc, however the 1000 alternator seems to have two yellow and two blue and white wires, wheras the 750 has only one of each of these?I have wiring diagrams for both bikes which again only seem to show the 1x wiring set-up, both engines are UK bikes, any ideas?First post, so please go easy on me!CheersChris
 
First of all,

I have never seen a stator (those are the windings in the "alternator") with more than three wires on any of our bikes. The stock wires were different colors, but it is common for aftermarket stators to have wires that are all the same color. I would suggest pulling the stator cover to see what's happening under there. :-k

The 78 GS1000(C/EC) used a separate regulator and rectifier. it had two yellows and two white/blue wires plus the white/red(?) that goes to the left handle bar switch. at what point in the harness the stator wires split and became two (a "Y" if you will) I'm not sure, but I will investigate it further I get home. regardless, the two yellows and the two white/blue wire are to be treated as "one of each" and are electrically connected. the purpose for the "extra" wire of each color was for the connection(s) to the regulator.

IIRC your '77 which also used separate reg and rectifiers, only had a "one" wire regulator.
 
Rusty is correct about the wires in question just being split. At the stator it self there are 3 wires (y, b/l, r/w) and a few inches before the connectors the y and b/w split to become 2 of each. You can just ignore the extra y and b/w wire and as long as you have replaced the original two piece R/R units from the GS1000 with a single R/R such is the Honda ones.
 
Hi Folks

And many thanks for your responces, very helpful.
