I swapped mine over as soon as I got the bike in 1981, it then matched the controls on the car.

The original 750 location was definitly high low beam on the right. Directional switch on the left.

But people very often swapped them over.

I now have a Triumph switch unit with everything on the left because I found the right hand side difficult to use with the throtle.

From the norton factory shop manual pn 065146:

"SECTION J19

HANDLEBAR SWITCH CLUSTERS
(1971 and later models)

The switch clusters are accommodated in light alloy castings. Whilst the switches are not sealed units, the method of assembly renders reassembly by an owner or dealer extremely difficult, if not impossible, and we must recommend against attempts at dismantling.

The right switch cluster includes, at the bottom, the kill (or cut-out) button and a spare button at the top. The 3-position flick switch operates the direction indicators which are available as optional extras. The switch functions as below:


1 With the lever in the central position and no buttons being pressed, the only leads connected are the White and White/Yellow. This is because the lower push button operates a normally closed (i.e. push to open) switch.

2 Pressing the lower push button opens the White-White/Yellow leads (Ignition cut-out).

3 Pressing the upper push button connects the White lead to the White/Red lead. This button has no function at the present.

4 Moving the switch lever to the upper position connects the light Green/Brown lead to the Green Red lead (L.H. indicators where fitted).

5 Moving the switch lever to its lower position connects the light Green/Brown lead to the Green/ White lead (R.H. indicators where fitted).

The left hand switch cluster accommodates the horn button (at the bottom), the headlamp flasher at the top and the two position dip switch. The headlamp flasher permits the headlamp to be flashed as an overtaking warning when the lights are not switched on.

The lever on this switch has only two positions, upward and horizontal.

1 With the switch lever in the horizontal position and no buttons being pressed the only 2 cables connected are Blue and Blue/Red (Dip beam).

2 Moving the lever to its upper position connects the Blue lead to the Blue/White lead (Main beam).

3 Pressing the lower button connects the White lead to the Purple/Black lead (Horn).

4 Pressing the upper button connects the White lead to the Blue/White lead (Headlamp flasher).

Note: These clusters may easily be reversed from side to side depending upon owner preference."

My notes...the factory schematics are also mislabled as to RH or LH
So originally the LH cluster has the blue series of wires
The RH cluster has the gn/w gn/r turn signals
and also note the facory says they are EASILY reversed.
A search of old threads shows this has been covered before...
Also note the PN's V.S. function are not clarified in the parts book!!!!! If in doubt, buy these by wire color not PN.

Dave's correct - Im wrong.

How embarassing is that !!!

How could I ride round for the first 10 years and still forget it ??? I changed it all to the left side years ago and have clearly lost the plot.

Luckly I still have kids to remind me where I live!!!

Thanks for the feedback to all who answered. Dynodave, that was a very clear explanation and gives me a clear understanding as to why there are differing opinions that people so adamently defend. I'm surprised this documentation snafu never made it into the INOA Tech Digest. Thanks again.

Dave is completly correct. I am completly wrong.

How could I do that !!!! I now remember it was the indicator being difficult to use with the throttle that made me change it over in the first place.

It's a wonder I find my way home at night!!!

Don't be so hard on yourself.
In this case, the shop manual is correct. Though not always. There are ocassional goof ups in the parts book too.
I leave my norton switches as original so the horn and hi/lo beam are the same as my 2 ducati's. My only norton with turn signals is my 75 MKIII. I don't find it a big deal to adjust. Turn signals are paractically never used for emergencies....
