A section of the front bumper appeared "dead' to receiving charge. My bad. The sticky side of aluminum duct tape does not conduct, thus a good chunk of my front bumper "looked conductive," but wasn't. Note the area (in the photo below) where the wire is taped to the bumper. That big strip doesn't connect to the wire electrically.

I cut a piece of wire and (using my pre-school skills) cut a piece of tape.

Taping the wire so that it bridges the "tape that taped the original wire" with main tape, the entire front bumper is now usable.
