Lew, a normally closed relay in that single wire, connected to a universal starter button under the accelelorator pedal makes it "old man forget proof". Pedal on the floor opens that normally closed relay to disable the alternator. Some EFI car ECUs have some AC clutch code that can be used to open that relay above a chosen RPM, etc.
A switch could also be mounted by the carb, to kill it @ WOT, but would also be just one more thing to deal with during tear downs, and working on the engine.
I finally just went to 16 volts.
