That is going to shut down the alternator completely.
Hmmm, I know what you mean. But I have excited disconnected 914 alternators by zipping them up to high RPM (not something you'd want to do right after startup).
My other solution in the race car (before I just removed the alt entirely and went "total loss") was to have a button that momentarily dropped D+ to ground. And I do mean very "momentarily", like just a quick tap of a spring-return button. Or, run the wire through an appropriate-sized resistor to fuse S9 (where the GEN light is connected).
Or, just ignore the light. As long as the voltage is being properly managed to 13-14V at the battery it shouldn't shorten batttery life.
Or - the correct answer - replace or rebuild the alternator. - GA
