Hi there
I've just dismantled the relay. It's basically two bog standard relays, three diodes and two resistors. All fine. I had carried out the tests detailed in the Haynes manual, the most of which are continuity between certain pins. It failed a lot of them where it's "out your probes this way, you should see resistance. If you reverse the probes and get anything other than open circuit it's broke".
However it does it's job by supplying the correct 12v and the relays work too. Testing the diodes and resistors on the board revealed they were doing what they were supposed to be doing.
Relay:

There was a wire off on the barrel when I got the bike, so I had to drill the security bolts out and resolder it. Barrel all fine.
Yes neutral light, it cranks, everything else works. As above all cutout switches work and are correct
I've ordered another CDI box today and on the hunt for a pickup coil but they aren't easy to find. That's about all I have left.
If I wave a screwdriver across the pickup coil whilst cranking it doesn't fire. The resistance only drops from 206ohms to 180ish too. It looks clean and fine but I suspect that's the issue
