i'm going to dual sport my 02 fx 470. studying the wire diagrams, i see the power for the lights comes from the unused yellow from the gen. it seems i need an additional regulator. the way the additinal regulator is wired is odd in that it looks like it could only use half the waveform. actually a better question is, what does the waveform look like right off the yellow lead? what gives here? also why does the horn operate off another power source....the battery? and how much wattage is avail from the lone lighting yellow lead?
some electrical questions

I think the yellow wire for the lights is ac voltage and the horn is going to be dc voltage from the battery. The lighting coil is separate from the charging coil.
I think the bike should be wired for a headlight already if I remember correctly.

Hi Doug,
The output from the stator is AC as Berger described, you need a 12v AC regulator for the lights, bulbs will work on either AC or DC.
The power output from one leg of the stator is around 60 Watts to be on the conservitive side but that is AC, once you put it through a regulator rectifier this could be around 50 Watts.
The reason the horn is on the battery is most horns will only work on DC voltage not AC and was all you could get at one time, but I think there are AC horns on the market now.

Because you are not using the full potential of the Alternator ie both circuits what you can do is connect both Yellows together and along with the Blue wire feed these detect to a Regulator Rectifier and convert the complete system to DC, now you have got the full output from the Alternator, similar to the Kokosan stator where you float the ground.
I've just not long since done an Alternator for DaleEO where he is now running the AC from the Alternator to a Reg/Rec to the battery and taking the power direct from the battery.
Some of the Huskies and KTM's have it wired like this from the factory.

Hi Doug,
No it doesn't matter which yellow you take for what, they are both common to each other.
Coastie, no the original is not man enough to handle all the power from the alternator, the Reg/Rec that Trailtech works well, rated at 150W.
Some of the pre 2004 systems ran a single unit functions the same way as the present day system, it is fed by two seprate windings, one comes out AC regulated only for lighting the other DC for battery chargng.

Sparks.
Most of the early elduros ran the entire electrical system off DC from both yellow wires parralleld together and ran across a Tympanium brand regulator. They had a separate rectifier downstream of the regulator.

Dougn1,
If it is any help, I can let you have a wiring diagram of how I wired up my FS650c for road use and used a regulator/rectifier taken from a scrap scooter and it was wired up to run all electrical items from the battery. However, I can also remove the entire battery/e-start circuits and still retain lights horn etc.
Let me know if you'd like me to sketch it out.
Cheers,
Simon

No worries chaps, I'll draw up a diagram and add it to my gallery for reference.
plumbbob,
I know exactly what you mean - we got stuck once out on Salisbury plains after the sun went down and both hi and low beam filaments on my headlight went bang! 8O

I just looked in my gallery and it seems I've already done a wiring diagram.
If you ignore the ignition switch part of the diagram it's pretty much all you need.

Simon,
Just been looking at your wiring diagram which is Ok, it's the feed to the Regulator Rectifier I'm trying to work out, is the AC input a single feed or double, if it is single input both Yellows need to be run in parallel and the excess is dumped either by a ground wire or the body of the unit it's self.
If it is a two wire input again the two Yellows need to be in parallel and the Blue from the stator feeds the other terminal.
By just feeding in the two Yellows the voltage potential is zero.

My apologies Sparks,
I should have made it more clear in the diagram itself that I'm using a regulator/rectifier from a scooter and I therefore left the detail out hoping it would cause less confusion in particular with the oem wiring diagram.
The unit I have receives two ac feeds from the generator and then two outputs via a green and red whereas in order to simplify the diagram to simply show how to wire the lights up to enable them to run off the battery, I only showed the rectified output.
I hope this clarifies the diagram.
Cheers,
Simon
