It's still blurry but from what I can see, it will work.
The operation theory is:
Basically the relay terminals you are using for mag ground are normally closed, that grounds the white wire, until you power the relay.
Powering the relay with the wire that normally was for power for the ignition coil,
opens the relay contacts so the magneto is no longer grounded.
That coil wire is powered in run with lights (if equipped), run, and start positions of the ignition switch.
Ya I know, you didn't need all that info, but it might help someone who wants to know how simple stuff works, and my coffee is still brewing.
