Norton Commando Wiring Diagram + Podtronics
I am in the process of adding a few different circuit diagrams to the site.
One of the most common upgrades or modifications for a classic british bike is to add a combined regulator/rectifier unit.
Our Commandos use a blue can capacitor, zener diode (which can be found mounted on the back of the z-plate) and rectifier unit.
A combined regulator/rectifier replaces all of these components with one package.
The most common manufacturer of these is Podtronics.
There are four wires to connect:
- Two Yellows – these are the AC input and pick up on the Green/Yellow and Green/White (connection can be any way round, as this is the AC side of the circuit)
- The Red – this is the Positive output and will join to the red wire if you are using existing wiring (it goes straight to the ground/earth of the frame)
- The Black – this is the Negative output (known as the hot wire) – it will pick up on the Brown/Blue wire (which goes via a fuse straight to the battery negative terminal)
Here is a factory wiring diagram with the Podtronics unit added into the circuit.

1972 onwards (four wires to the master switch) PNG 3066×1841
I hope these will be useful to someone!
