Norton Electra Wiring Diagram

What is it?

The Norton Electra was in production for a very short period of time – only 1963 to 1965.

It has a 400cc engine – a mildly enlarged version of the engine that was originally fitted to the Norton Navigator.

The frame was a strengthened mild evolution of the frame used on the James/Francis Barnett – so they were very much drawing from the AMC designs they now had access to.

Unlike the Navigator and Jubilee, the Electra featured the ‘proper’ Roadholder front end, it sported an 8 inch brake at the front and a 7 inch brake at the rear (both ‘borrowed’ from the Dominator).


The electrics were a bit of a mish-mash on this bike.

It was mainly WIPAC wiring and components, however the electric starter is a Lucas M3 unit, and the turn signals (quite a novelty to have on a bike in the mid-sixties) were supplied by German company Hella, and can also be found on BMW motorcycles from the same era.

I am very lucky to own an original WIPAC Service Manual, so have scanned the original wiring diagram. It is much better quality than the one you can find in the Norton Electra Workshop Manual.

Simpler, more colorful

I don’t know about you, but I don’t find the original wiring diagram very easy to read?

So, much like the work I do on Norton Commando Wiring Diagrams, I have taken the original, colorized it, and massively simplified it.

Believe it or not, this is the same diagram for the same bike. Just by moving a few components around on the page, re-routing the way some of the cabling has been drawn, and adding a splash of colour, it’s made it a million times easier to read and understand!

I have added a colour key on the page. WIPAC tend to use dark and light versions of the same colour, plus their brown, dark red and maroon are a bit ‘close’ – so the key is a big help.

Wipac ‘vs’ Norton

Norton made a minor change between the schematic that Wipac created originally and published, and the version that Norton later published in their factory workshop manual.

The change is pertaining to the behaviour of the lighting – in the “emergency” ignition switch position, the lighting is not operable based on the original Wipac schematic.

However, with the Norton’s later revision, the lighting behaves the same in both normal “ignition” and “emergency” switch positions.

I assume this change was due to the need or desire to get home safely under the cover of darkness with lights on!

  1. Hi,
    I am in the process up ‘updating’ a 1960 Norton Navigator Delux.
    Convert to 12V, fit electronic ignition, maybe indicators.
    Can I ask what drawing package you use to create you circuit diagrams? And would you be willing to provide me the source of the Electra diagram so I could modify that?
    I would naturally send you my diagram once completed.

    • Hi Tony,

      I just use the free application for all my schematics – it’s very much like me not expensive, not clever and not complicated!

      Here is a quality scan of the factory Navigator diagram straight from the Wipac book:

      It is much simpler to work with than the Electra one.

      Hope that helps!

  2. Hi,
    Thanks for the swift response but your modified electra one is very close to how it will end up, simply remove the starter side of things and add in the electronic ignition. And your layout is way simpler than the original one.
    Do you have it in native image type (*.PDN), or alternatively *.PNG
    Saves me starting from scratch. As I say, I will send you my completed one if you wish.
