Need a "74 mk2a Wiring Diagram

Ron

Standard versions are available on Grant Tiller's website here https://granttiller.com/norton-commando-wiring-diagram

Also custom versions, e.g. electronic ignition, here: https://granttiller.com/

Hope this helps

The 72/73 diagram works for mk2a, well before I added my own changes. Grants website confirms this. So best if you explain your differences.

Help yourself to anything on the site.

If there is something you need that I haven’t covered, let me know and I’ll do whatever I can to help.

A word of thanks to Grant for his indispensable diagrams; I am in the middle of fitting a new wiring loom and his corrected versions of both the logical diagram and the "Lucas" loom are proving a godsend.

One thing that would be useful to see on the Lucas diagram is an indication of which sections of the loom pass through which of the various grommets on the frame.

Also, but this may be unicorn territory, I'd be interested to know where the factory fitted cable ties (assuming, possibly optimistically) that they had any particular system …

It's not unicorn territory in the old 1970's Honda factory manuals.

With nowt else better to do last winter I restored an old Honda step thru which came to me with the original factory manual.

I pulled it to bits and then struggled to remember the wiring harness routing when re-assembing.

The manual has an illustrated section  'cable and wire harness routing'.

Would be a welcome addition in Norton manuals too. 

Italians also have unicorns — at least, modern ones do. The workshop manual for my ST3 has elaborate photographic documentation of the routing of lines of all kinds, not only electric but hydraulic, etc.
