The assembly instruction manual (AIM) shows all of them. There are several. Are you looking for any one in particular?

Don't have any pics but can tell you where some are.
Under the car the battery grd comes out of the box to the frame rail.
Passenger engine mount to the frame.
Antenna to the frame.
And I'm sure there's one or two more but I don't think it would affect your volt gauge....

Rear frame for tail lights, what circuit is giving you a problem?
No diagram but here's a schematic.

There is supposed to be a Bonding Strap on the passenger side valve cover to a stud on the firewall with the ground for the wiper motor and the blower motor. There is a large ground cable under the passenger side motor mount to the frame. There is a ground wire on the alternator mount to the main engine harness. #1 drivers side mount frame to body. Drivers side rear light harness (fuel gauge and lights) to frame next to the muffler and the antenna motor. Couple more up front for the forward light harness to the radiator core support.
Probably others I can't remember.

Alternator not charge but tests good??? Hmmmm. Did you try reving the engine? Most new alt. are self exciting and you need to rev the engine up to 2000 rpm.
If that doesn't work, your gonna have to chase your 3 wires down and make sure they are connected.

11 volts is not enough!
I'll take a guess that the regulator in your alternator is bad.
Try a new alternator and see if the problem is gone, if not return it and lets check the wiring.
