Hi Dave,
Looking at the wiring diagram, the switch is open for 'off' and closed for live. Its unusal as most bikes I've worked on, the switch is to earth. I have tried it in both ways, yes. There are two wires going to the switch, one is a feed from the fusebox and the other goes to the pgm so I guess the kill switch is a power switch for the pgm in effect.
The pgm and loom was sold to me untested, I'm hoping that I didnt kill it but fail to see how I could have done. Even before I created the circuit so dont think that could have killed it.
I'm waiting on the two I bought off yahoo Japan to arrive then I can continue.
I have access to an Oscilloscope, yes. We use it for checking inverters but recon it could be used for other purposes
Cheers
Paul
