Custom Norton Commando Wiring Diagram – Luke Turner

Grant Tiller

This is a custom wiring diagram for Luke Turner from the Access Norton Forum and Commando Facebook Group

Luke has fitted a Boyer Bransden MK3 electronic ignition to his bike.

He’s also fitted a Boyer Bransden Power Box regulator/rectifier with built-in Charging Light.

This means that we need to remove the factory assimilator, and re-purpose the cabling up to the warning light in the headlamp shell.
