Bad news: replacement alternator self-excites.
Bad news: the replacement alternator self-excites at engine speeds above 1500rpm, turning itself on and not turning off unless I stop the engine and wait for a minute before starting it again. This means I can't disable it.
Well, I could disable it by interrupting the main output cable, but that makes it much more difficult to reconnect it, and much more difficult to arrange an ON/OFF switch for it.
It's a used alternator. Didn't cost much at least. A Bosch. I don't think they're designed to self-excite, so I guess the rotor has developed a degree of permanent magnetism over the years, but I'm only guessing.
