Wiring Diagram for '74 Mk11

thunderbolt · Jun 16, 2022

Hi All,

Can someone point me in the direction of a wiring diagram (preferably from a Norton workshoip manual) for the '74 Mk2 (not Mk2A) Commando please?

I can find one for the '72 and '73, but not the '74 year model. I guess they are similar, but not sure.

Any help really appreciated.

Thanks Don

There isn't one for '74.
The '74 wiring is the same as '73 (whether it's a Mk2 or Mk2A Edit: unless it's a JPN).

I used these as a reference for installing a new harness on a 74' MK II.
Then I changed a bunch of stuff around to custom wire certain circuits for my liking and now the schematic will only confuse the next guy to work on it.
But I did take lots and lots of photos.

A few corrections to B. Turnbull's original on this one.
Most notably the org. had the number 3 & 4 reversed on the master switch.
