I'm wiring up a 76' XS650 right now with no avail. I'm just running the basics. Headlight, Taillight, Brake Switches to both, charging system with a newer reg/rec, and using the Pamco Ignition. The bike is kick only and there is no turn key ignition only a hidden switch. I don't know if I need to mention anything else, if so please let me know. I'm having no luck with it. A wiring diagram that works would be greatly appreciated. Thank you.

six....,
Can you be more specific about the "newer reg/rect".

It's just a combo reg/ret plugs into the harness from the stator/brush.

Well, choose one of these:
1. A stock Yamaha combo reg/rect from a '80 to '83 XS650
2. Mikes combo regulator made for pre '80 models Part Part #24-2089
3. Mikes combo reg/rect made for '80 to '83 models Part #24-2087
4. Some other unknown combo reg/rect.
There is a difference in these regulators as far as the way the brushes are wired. The reg/rect for the '80 to '83 models require battery on one of the brushes. Combo reg/rect for the earlier models require ground on the same brush. Your model of XS650 has that brush grounded. You can use the later model reg/rect on your model if you isolate the grounded brush with nylon screws and apply switched power to the brush.
So, in order to provide you with a wiring diagram, we would have to know what kind of regulator you have.

Well, I'm going with number 4. I can stay the brush is not grounded by nylon screws and is grounded to the battery so of now.

Okay okay. Finally made it out to the garage to get a look at the reg/rec. It's a 7 wire unit consisting of.
1. 3 White wires.
2. 1 Brown wire
3. 1 Black wire.
4. 1 Red wire.
5. 1 Green wire.
Please help!!!!!!

Well, I will have to assume that you have a #1 from the above list. We wont know for sure until you have wired it up and pressed the button. Here is a dandy wiring diagram for that situation. I did not make this drawing, some other member did and it's a very good diagram that is easy to follow, so you will have no excuses if you screw it up!!  That little rectangle with the brown and green wires represents the brushes. If I am correct about your regulator, you will have to isolate the grounded brush on yous with three nylon screws, like this:  I also cannot take credit for this picture. It was done by yet another member. So, get started and report back with your questions. Good Luck!  |

I did mention it being kick only. So what do I do with the started solenoid?

sixthirty,
Nothing. You can remove it or just leave it.
If you are always going to just have a kick only arrangement, then you do not need the heavy duty cables from the battery. You can just use 14 gage wire from the positive terminal to then main fuse and also 14 gage wire from the battery negative terminal to frame ground.

Thank you! So my understanding is, instead of wiring the starter solenoid I wire directly to the hidden on/off switch I plan to use. I will definitely give this a try and report back with my findings. Thank you again for your help. I'm excited to see how it runs with the new ignition.

No. Wire from the battery to the fuse holder for the 20 Amp fuse and from there to the switch. Per the diagram.

Does the brown wire from the reg/rec wire to the switch then?

Yes. Take a look at the wiring diagram. It's all there.

Okay, got it completely wired. Headlight, Taillight, and Brakelight are fully functional. Go to kick it over and it seems like it isn't getting enough spark to fire up. Tried it both with the nylon screws and without. Seems to have more spark without the nylon screws. Want to make sure I have the wiring from the Brush and Alternator to the Regulator/Rectifier correct. From the Alternator it is 3 white wires on the top of the connector, then 1 blue wire, an empty space, then 1 green wire on the bottom with a black ground separate from the connector. Connected to the Reg/Rec is 3 white wires on top, 1 brown wire, an empty space, then 1 green wire on the bottom. So connected it's whites to whites, blue to brown, and green to green with the yellow wire from the Alternator capped and the black grounds connected separately. Does this sound correct? A friend of mine tried to wire it previously and may have switched up the connections. Please tell me what you think. Thank you.

The three whites from the alternator hook to the three whites of the reg/rec.
The blue wire is for the neutral light.
The green wire to the green wire.
From the alternator there is a black or brown wire, depends on if the alternator is 79 and older or 80 and newer. The older has the black wire and needs the three nylon screws.
The newer has the brown wire and doesn't need the nylon screws.
Once you determine which alternator you have hook the brown or black wire to the brown wire on the reg/rec. Now hook a brown wire from this connection and hook it to the switch.
The red wire from the reg/rec to the battery positive.
Black from the reg/rec to battery negative.
