We have been down the road of the electrical issues on my R75/7.
Now it has been established that the NLA switch assemblies are a problem. I found a turn signal/starter/kill switch and it functions properly.
I also found a left assembly. The problem: it is from a later bike and has no on/off/parking switch. I've gone through the circuit diagrams, and admittedly, I haven't really used them since electronics class so many decades ago, and can't find a way to use this part.
So my question is if there is anyone in the group who can tell me which wires to bridge to allow headlights always on to use this switch?
By testing the switch with a Ohm meter, find the power feed going to the headlamp Hi/Lo switch and plug it to the Gray/Black on the multi-color connection board. This will by-pass the lights OFF during cranking relay, but it will get you started.
• If you are running an H4 LED headlamp bulb, then the relay may not be that important anyway.

Keeping an old Airhead running great is the true test.
I made one more attempt to get the original switch working this morning, and was successful! I get high and low switching, but wasn't able to get the on/park/off lever to function, so I glued it in place and have lights. I will try your suggestion over the winter. I want it on the road now...NOW! LOL
The next step is getting my Contis replaced as apparently they are recalled. My new Avons just arrived.
Thanks for the help!
Are you doing the tire fitting yourself ?

No, since someone else is paying for it, I'll skip a job I loathe! BTW, these Avons are really, really soft. The Conti front comes in at 60 and the Avon is about 50 on my Durometer.
