This is a custom wiring diagram for Steve Black aka “raleighmodel6” from the Access Norton Forum
Steve has some good mods fitted to his Commando.
Probably the star of the show is the Colorado Norton Works Electric Start Conversion.
This really makes the bike worry free to ride in today’s traffic. no more panicking when you stall at the lights, just press the button and be on your way!
A popular upgrade in the late 70s and early 80s is the Lucas RITA electronic ignition system.
Easily spotted on the Norton Commando, the Lucas RITA needed a larger points cover to house the large “reluctor” plate.
Like many, Steve has fitted a Podtronics regulator/rectifier unit in lieu of the zener, rectifier and capacitor along with a 3 phase alternator for better charging in stop/go traffic.
Lucas RITA units are no longer in production, but a popular source for spares and repairs here in the UK is Rex’s Speedshop
Steve has fitted a SparkBright voltage monitor in lieu of the unreliable warning light assimilator.
Steve has also fitted twin horns on his bike – a great safety addition.
In order to lighten the load going through the handlebar switchgear, the twin horns operate via a relay.
Here is the electrical wiring diagram for Steve’s bike:
