A little background info:

Every year for the last 15 or so, a group of us take the old cars to a nice show about 155 miles away.
This year a fellow showed up with a very nicely restored 56 Crown Victoria. As he was pulling in,
I noticed his headlights were very dim. I asked about it and he didn't know.
The car wasn't restored by him, but all the wiring was replaced.

Now, on my car (also a Crown Vic), I've asked many questions, and of late, had a response
regarding an unused hole in the driver's side head: That it's for a Body to Engine ground wire.
I wonder if there are, or are supposed to be, any other body grounds?
Anyone know anything?
So far, I've got a Battery to Frame ground, a Frame to Engine ground, but only the Body to Engine
at the firewall area.
Just asking all this, as I think this fellow must have had poor grounds or very low output from his
generator. or a poor battery.
Also, I've seen a kit for sale that utilized relays to "fix" this problem.
ANy thoughts?
