Yes. But if I shut it down again the voltage meter would continue to read 14+ volts. But if I had turned the alt back off, killed the injectors, and then bump started, the voltage would be back down to 12.6 or 12.2 or whatever.

That's clever. I was able to do my splicing from above, but it was very awkward (and I have long thing hands and fingers).

That's how I have been disabling my alt these last 5 months. No CEL ever. It will work perfectly. Whenever you need the alt again, you'll just need to plug it back in. That's fun when the engine is hot! But it will work. I was at a bone yard today. The only sixth gen civic was picked completely clean. If I go to another before you get your connector, I'll see about grabbing one for ya! Snip snip... in the mail!

Car alternators use external power, brushes and communtator to excite their field windings, its more compact and cheaper this way.
Its also easy to sever this type of field winding connection.
This would mean getting inside the alternator?

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.
