OK, per multiple recommendations, I connected a ground from the negative battery post to the body. The positive, which mainly goes to the starter, is grounded to the frame, per usual. I did not ground the frame to the body.
So, when I did this, there is a noticeable difference in my starter motor's strength and the speed with which it turns the engine over.
I disconnect the negative ground, the starter is back to full virility; reconnect it, it take three times as long and almost struggles, sort of like it is not fully glowed (this is a 2H), only different.
Battery: new and well charged.
No other electrical issues except a bad water temp gauge, and the starter's brushes need replacing (1-20 or so tries, it needs a little "percussive adjustment").
Any ideas? Weird, huh?
