Norton Commando Wiring Diagram + Power Arc

I have fitted a Power Arc electronic ignition to my bike.

These are sold, I believe exclusively for Norton Commandos by Fred and Ella at Old Britts.

This is a brilliant company to deal with, polite, efficient and courteous.

What Old Britts don’t know about Norton Commandos isn’t worth knowing!

The reason I have gone for the Power Arc kit is two fold:

  1. it supports several different ignition curves, which you can tweak yourself on a laptop, then easily switch between on the bike.
    I like the idea of an around town map and a fast road map – and I guess time will tell how practical and/or useful that is!
  2. the sensor is optical – most of the common electronic ignitions systems (like the brilliant Tri-Spark, which I have fitted to other bikes) use a spinning magnetic rotor.
    The Power Arc uses a slotted optical disc and encoder arrangement, so in theory should be more accurate, and have better longevity.
    Again, time will tell on that one!

Here follows the wiring diagram for the Power Arc electronic ignition.
