Don’t have any dash, dome or tail lights when headlights are on?

Also the thick hot lead to the back of my alternator.

That is the alternator output wire. Think of it as going to the main splice.
When the alternator is producing power, electricity is flowing from the alternator to the main splice.

The problem is that I don’t know where to find the ground for the alternator to check it it’s up to snuff? Is that green wire lead the ground?

Ok Maybe I wasn't clear.

Anyone who is saying the output stud or the wires attached to it are ground should be ignored. They are clueless.

and maybe this wasn't clear either.

The alternator ground on traditional US cars is almost never a problem. They are firmly bolted to the engine with the mounting bracket and belt tensioner, so ground is pretty much "there."

What we are saying is what Joey just said: there is no ground wire to these alternators. The alternator grounds both circuits through the brackets and engine.
One circuit powers the spinning electromagnetic. The green wire is the one that supplies power supply for that.
The other is the output circuit consisting of the non-moving windings and rectifiers to convert the induced A/C into DC power.

This can work, but its not factory. I would take the twist out but Del knows more about whether it matters.

FWIW Factory location was here. Mine is covered in insulation due to the headers but its the easiest photo for me to find.
