Tri-Spark unusual problem

ericg said:

And now for an interesting one.
I've just installed a new stator unit after the old one suddenly failed after 13 years.
It just refused to produce any spark after I stopped for a break in the middle of a ride.
Anyway, with the new unit fitted it now starts, run and idle as well as before but the strange thing is I can't stop it running! The ignition switch is useless, though it seems to behave as it should after multiple tests. And, wait for it, it continues to run with the battery disconnected at the fuse!
I've just sent a message to Steve Kelly, waiting for his reply.
Any clue from someone here?
Thanks.

Thinking about it if the engine runs with the battery disconnected the only source of power would be the alternator. I'm gonna check if I've not switched regulator connections.

Found the problem in the end, it turns out that the power output from the regulator was connected along with the power to the ignition. So there was still power from the alternator with the switch off.
I must have crossed connections when the old unit failed, trying to find the problem by the side of the road. Silly me!
