Well, had both blue/red leads off the b/motor and tested the yellow wire. Meter shows voltage. I normalized everything back up and the b/motor WORKS!

I wiggled the wires around at the regulator and the b/motor and nothing happened. I cleaned up the contacts at the b/motor with some sandpaper and normalized the wires again. It still works. I'm going to normalize everything now and go for a small spin around the block and see what happens. Thanks again, Arthur.
