Hi, I'm looking for a wiring diagram, or written discription to identify what color wires go where on a 5A Bosch magneto. Mag to coil ? etc. ?
Thank you

Rob,

I think this is the one you want.  Let me know if the wire colors coming from the mag on yours are different, as there were a few styles.

Thanks,

Yes it is the correct diagram Kevin, and that helped immensely. I now have spark. Though, it did not have spark until I by-passed the first terminal, and took the blue wire directly to the coil. I'll figure that out later. But thanks a ton for helping.
On a '69 Sachs K100GS.

Rob,

Glad it helped.  Check out http://www.vintageconnections.com/ I use these on everything now and it eliminates the headaches associated with terminal blocks all together.
