HELP! – Electrical Schematic for Bobber Project

[summers420us]

I just finished working up a schematic for the last part of my bober project and could really use your help to make sure that the schematic will work without frying anything.

Specs of what I got:

1975 XS motor with standard alternator loom that has 7 wires: 1 yellow (by itself), 3 Whites, 1 Brown (could be Black), 1 Green and 1 Blue. (I am NOT using the stock wiring harness other then the Alternator Loom)

The Solid State Rectifier Regulator from MikesXS.com Part #24-2089 that has 7 wires: 1 Red, 1 Green, 1 Orange, 1 Blue, and 3 Yellows. www.mikesxs.net/mikesxs-electrical.php?category_id=2.4

What I am trying to accomplish:
I want the minimalist wiring harness. As few wires as possible to make it work. I do not need a horn, turn signals, front brake light switch, instrumentation, or any idiot lights. Head, Tail, Brake and Ignition is all I am worried about. ;D

Thank you in advance for your comments or suggestions. Let me know if you think it will work or won’t and why. If you see anything wrong with my diagram please let me know. Also the remote switch is a Key Fob type so that there are no switches visible on the bike and all wiring will be stashed into the frame. 8)

I'm right with you - I need to do exactly the same thing for a friend's '75 XS. It looks like you've already done a good bit of the research. We may be doing this at the same time, or you might be a little ahead of me, since we've got a little bit of engine work to do. Let me know how this works out - if you get done ahead of us, let us know how it worked out. Thanks for your pioneering, and good luck with your project. Jim

I noticed you made no provisions for a horn, starter, engine kill switch or one of the two brake switches. Was this intentional? I can understand leaving out the starter and kick starting the bike, but the horn, engine kill switch and second brake light switch are safety items. I'm working up two drawings in Microsoft Visio now - the first will be a schematic diagram with regular electric symbols, and that ones about 80% done. The second diagram will be a block wiring diagram like the one you have here, with the different parts in their relative locations on the bike in the interest of crating a wiring harness. Do you have a schematic or wiring diagram for the rectifier/regulator you're using? Regards, Jim

I'm working on the area of the connections from the alternator to the rectifier/regulator from Mike's XS. I'm confused about the connections from the rotor. On the original Yamaha drawing, the black lead from the rotor goes to ground, and the green lead goes to the regulator. On your drawing, the black lead (ground) from the rotor is tied to the supply lead that powers the bike. Without a schematic or layout of P/N 24-2089, I can't tell for sure, but at first glance it appears that it won't work as drawn. can you scan the the drawing or connection layout of this part & send it to me at jhicks35 (at) bellsouth (dot) net? Without it, I'm not sure. Jim

how do you modify this to work for a later model without pionts? or is there a different diagram somewere?

[angus67]

or does any one have a diagram for a electrical sysstem without battery. Im not using electric starter,
