i need help wiring

[Boondocks]

Here is a link to the diagram for my bike. http://s28.photobucket.com/albums/c204/toonce/?action=view&current=WiringDiagram.jpg&refPage=&imgAnch=imgAnch6
I have three yellow wires coming from the stator to the R/R. From there I have a red wire from the R/R that branches out in two directions. One goes to the ignition switch to provide power for the parking light and the other goes to the fuse block and on to the battery. The red to the ignition switch also runs back to the fuse block as an orange wire to split off and provide power for the three 10 amp fuses for the various circuits.

The wiring diagram for the bike doesn't reveal the workings of the R/R, or how many stator leads are regulated. To know how the R/R works, you would need a schematic of the R/R itself. The factory shop manual has it for my bike.

so on my '78 would there be any benefit of wiring that loop in before the new R/R? or should I just skip it? my head likes the idea on have less unconnected wires floating around, but if it makes no difference i can live with a couple of loose wires.

There is no benefit if you always leave the lights switched on. Turning them off briefly won't hurt, but it you run with the lights off it's best to run the wire through the headlight switch.

If you leave the lights on after starting the bike, I would bypass the switch and connect all three stator leads directly to the R/R.

I've got the factory manual and it shows all three leads are regulated. All three have three diodes and all three go into a control unit in the R/R. If I had time I'd scan it and post it. If I remember to I do it tomorrow. The lighting switch comes into play after the R/R.

All R/R's have six diodes for full wave rectification (DC conversion). This is the rectifier circuit and does not identify the manner of regulation. The key to how many stator leads are regulated is whether they flow through a SCR. If there are three SCR's, all stator leads are regulated. If two SCR's, this is the R/R designed with an unregulated light switch circuit.

Actaully my diagram shows a total of 9 diodes. Links to the pages.

The three objects near the control unit that look like diodes are SCR's, so all three stator phases are regulated in the R/R.

alright all wired up, and it charges good, runs great.
i'm riding again.
just in case anyone wants to know. i used a R/R from a 05 750 gsxr, it was about three times bigger than the old rectifier, but, it has all the same leads and works great. i by passed the headlight loop as i leave my headlight on most of the time, anyway.
thanks for all the help.
