Guys, thanks so much for the quick replies. I just went back to the parking lot and tried the jump. Unfortunately, still nothing. It was too dark to thoroughly check the engine ground or tap on the starter, but I'll go back in the morning.

(Just to make sure I did the jump right: turned the key "on" and touched the two ends of a wire to each of the two terminal screw heads in Craig's photo. That should have fired up the starter, right?)

I'll report back again tomorrow... thanks again.

Charlie
