Welcome to the forum! Many of the members are geniuses and some know some magic, but I think we need some more detail.

What are the wire colours on the R/R you want to connect? Do you have a wiring diagram for your bike?

Hi Mr. woodytwoshoes,

What color are the wires you're working with? If it's a 5 wire unit you should have a black and a red wire. The rest may be something like white with a red stripe, white with a green stripe, and/or yellow. Those three are all the same and connect to the stator in any order (consider them all "yellow"). See below:



The above diagram is for a 6-wire unit so you can ignore the black "sense" wire. The Honda r/r unit pictured above uses green for ground.

You'll want to check out the Stator Papers. The link is in your "mega-welcome" below.

Now let me dump a TON of information on you and share some GS lovin'.

I just stopped by to welcome you to the forum in my own, special way.

Be warned that there are lots of too small R/R's out there that will strain your charging system or worse. Any numbers on this unit? Spend some quality time with Mr. Basscliff's info and you will discover amazing clues to solving typical suzuki problems.

The rec has a red, black, two white and a brown. Love this site! Hard to tear myself away and do some work on the bikes.
Thank you,

I forgot to mention that, yes I do have a wiring diagram for the bike.

Hi,

Forgive me for being in such a hurry. Your bike may have come stock with separate rectifier and regulator units. Most of us are using an upgraded, integrated regulator/rectifier unit, as in the wiring diagram I posted earlier. If you are still using separate parts then we'll have to discuss the proper wiring.


Thank you for your indulgence,

BassCliff

Hello again, and yes I am using separate regualtor and rectifier for now anyway. I do have a spare R/R 6 wire that would work? It is a shindengen 4LO-AO. It has a red, black, brown and three white wires.
Thanks so much,
Woody

Woody,
Have a look at this thread for some detail. http://www.thegsresources.com/_forum...d.php?t=134690
The unit you mention above does not seem like a workable one and may be off a smaller Kawasaki. It only has two white wires which usually indicates a two phase alternator and you have a 3 phase one.

This one may work and may be off a Kawasaki as they use white for the AC wires. See BassCliffs diagram sent earlier and just make those three yellow wires white.

Here you go, use BassCliffs wiring diagram he posted earlier for you:
Your 3 white waires are the AC input and replaces the 3 yellow wires in any order.
Your black wire is ground and replaces the green wire.
Your red wire +12V and is the same as the red wire on the schematic
Your brown wire is the sense wire and must go to a switched +12V and replaces the black wire.

The number you quoted is not a Shindengen number which should start with SH xxx, Your replacement must be able to handle the current of your charging system and one off a smaller bike may not be suitable

Hope this helps
