Yes, there's no reason why you can't have the warning light (and assimilator) and the ammeter if you want to.

I think perhaps that is the wrong switch for your 1970 model although I cannot remember seeing a switch with that (5,6,7,8) terminal layout.
The switch should be a three position type: (1)OFF - (2)TAIL, PILOT, INSTRUMENTS - (3)+HEADLAMP.

Is there a number stamped on the metal casing of the switch (you may need to remove the switch to see the number)?

According to Dave's wiring diagram, the tagged switch terminal layout should be 1,4,6,7(no wire),8.

Firstly, do not connect any red earth/ground wire to the switch.. Do you mean a red/black [RB] (pilot light) wire?

According to the workshop manual wiring diagram, http://rocbo.lautre.net/technique/norto ... p/149.html
brown/white [NW] connects to the Zener diode, not the lighting switch. white/brown [WN] goes to the switch T4 (disregard 'WG' as marked on factory diagram near the switch as it should be WN)

There should also be a blue wire to the switch (terminal 8.) ?
 
Dear Sir,
the switch comes maybe from another lucas shell and it has only one position, i mean it go on only one time, not goes rear.
I am very sorry but the numbers are 5/6 and 7/8, the numbers 1/2 and 3/4 have no fits.
What can i do?
I need a switch with tre positions?
Regards.
Thanks.

Could you please explane to me.

I sent Piero a pm with more detailed instructions on the switch and colors, but if it's a 2 position switch, he needs to get the correct one. PM Ron L, he seems to have some of these early electrical items. I have a part number for the switch as 35710. Good luck on that one. Someone has one I'm sure, it's just finding it.

Piero e-mailed me, apparently he has bought another switch from the UK.

Piero's original switch, unfortunately it's number is as yet unknown

That switch is certainly not anything like the one in my bike.

Dear Dave and Les,
please, i need another help about my wiring ystem.
I have to fit the handlebar switch of 1972: it has, like 1970 wiring and like the photo Davevsent me, the wire blu, blu white, white, blu red, but it does not have the brown black, but has a purple wire!.
The brown black from the mine wiring system, that i have into the shell, would be the horn push.
What i can do, fix the brown black with purple?.
Thanks a lot for helping me.
Best regards.
Ciao
Piero
 
I sent you a PM with colors and schematic. Use purple/black for missing wire, I guess.

The original pre-71 (Wipac Triconsul) switch cluster has a 'ground' horn switch, the 1971-on horn switches do not operate on the same principal, as power is sent from the switch to the horn, so it presents something of a problem, and Piero's Commando still has an ammeter so it is not just a case of joining various horn wires. Piero also e-mailed me, so I replied, outlining the problem and suggested he uses a relay which should work around this.
 
Yes, here's the pre-71 Wipac harness that goes into the headlamp. It's pretty confusing from the book schematic because it's not separated out.

According to the pre-71 wiring diagram, and from what Piero said, the wire between the horn and the switch is brown/black [NB] and not brown/blue (BRN/BLU) which you have marked on your drawing?

Edit: Also, the power wire from the lighting switch is marked as blue on the manual diagram and not 'BRN' as per your drawing? It's a blue wire in your photo.
 
You're right about that. I probably just read B as blue instead of black (must be the old timers disease). Next time I have the headlamp apart I'll check it on mine, but I seem to remember I had the correct colors on my harness that agreed with the schematic. Ron L sent me a Wipac that I traded harnesses on because my hi/lo switch was broken.
