This is a remarkable set of tests. Thanks.

I'm sure the switch will work, having watched how you have tested and developed it. What a great example of careful modding this is! When you have reached your conclusion, I'll edit the OP to link down to your final alternate build. Or you might want to start a separate thread that walks a modder through a build and links to these test of yours.

In my still limited experience, the alt is fine after several months. But I don't switch on/off often at all... I run with it off all day unless I am confronted with a long drive or night driving, then I will turn it on more often or continuously.

I thought it would not be best for the alternator to disconnect this wire. As most of you probably know when not connected to a battery alternators make very crude 14vdc. The battery dampens the spikes so you get smooth 14v. Without the battery on the circuit the alternator would have been powering itself (the regulator) with this rough power. I did not think it was a reliable long-term solution.
I think a guy on here a couple years ago fried hIs Metro alternator this way. Good thing to avoid!

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
