Ok....I'm helping raildog with rewiring his triumph. I thought it might be a good idea to have a thread about basic wiring for most any motorcycle. This will be about kicker bikes....no electric starter. I will start off discussing how I set up my triumphs.

First thing is decide what to keep and what to throw away. I keep the factory alternator if it is good, and also the lucas points. I usually keep the stock headlight and maybe go with an aftermarket tail light. A key switch is nice, along with some sort of a dimmer switch. I don't like a battery, so that gets eliminated.

My shopping list will include a HD points type coil, a tympanium (solid state regulator), and a big capacitor to eliminate the battery. About a hundred bucks covers all this stuff.

Your choices may be different...possibly an electronic ignition, which means a battery get added to the system.

I'll stop here for now, and open this up for discussion and questions....or suggestions about options. Then I will continue with the plan for raildogs bike.
 
Yes, a key switch will work. I highly recommend purchasing a simple volt/ohm, digital tester. I got mine at radio shack for about 15 bucks. I never travel without one. I'm sure no electrical genius, but this tool has helped me a bunch in the last few years. With one, you can test the swap meet switch and determine which terminals are "hot" for each key position. It can also test your charging system after everything is hooked up....just a great tool for the garage builder.
 
TR6's diagram is a good layout. It would work in many applications with only minor changes for different bikes....for instance, on an HD, you would have a single coil, and negative ground. I also switch my triumphs to negative ground...doesn't seem to make any difference, but easier on my brain.
