1977 Strada 6 pole ignition switch

[RedVee]

Would anybody have a 6 pole ignition switch for my 1977 Strada, please?

I recently bought one of these, direct swap on my 500, same wiring connections and fitted the original bracket.

I’ve used a Camino switch on my 350 too. Works fine, although a word of caution to anyone reading this using a replacement non original switch of any type-

The switch I got had the right combination of pins which connect or disconnect in the various key positions (actually I think I had one switch position (parking lights) which couldn’t quite be made to work out but to be honest that doesn’t bother me and actually stops me accidentally leaving them on and draining the battery!)

The spade terminals on the Camino switch were also of the slightly smaller type, so I made up a new switch sub loom with the smaller spades at the switch end.

A word of warning- the mapping of pins 1-6 was not exactly the same as the original CEV so I had to work out which wires to put where.

If you put 12V onto the green wire you’ll blow up your transducers, which is easy to do if you wire the switch wrong!

There should be a diode on the green wire at the fusebox to prevent this happening but not all bikes had one and of course may not still be present after 40 odd years.

So, check a diode is in situ and functioning correctly and do a continuity test on all the switch pins in all the key positions to confirm which wires go to which pins.

Thanks for adding the advice Tom. I was unaware, mut have been done to my 500 by a PO, it certainly wasn't a CEV lock which I replaced and as mentioned my new Camino lock was a like for like replacement with the connections.

That's useful to know, Tom. I don't suppose you have a diagram or list of what connects where, for my man?

Safest thing to do is to do a continuity check of your existing switch positions against all pins in turn, but for me the below mapping of what is connected in each position for CEV to Camino switches and wire colours is what I ended up with. Position 1 is the redundant one.

Fundamentally, green should only ever be disconnected or connected to earth.
