1966 Ford Thunderbird.
When I go to start the car I get nothing.
The Headlights do not work.
It seems like I lost all electrical!
Car was started just 3 hours prior to this failure.
Battery is just fine.
Thank-you for your time.

Just as far as diagnostic routine, I'd still have to check your battery. Have you had the battery tested? If you have a digital multimeter you can do some testing, yourself.
Check battery cables, check fusible links. Check fuses in your fuse box, see if any fuses are hot/voltage.
I don't know if I can find any wiring diagrams for this model year?

I found this wiring, just follow the positive battery cable, check for voltage at all the branches off the positive battery cable.
The negative battery cable can also cause problems.

Hello, Thank-you for your time.
The battery is just fine.
When I try and go to even just start it. It is sparking at the battery.
It has to be something electrical.
And I have no idea where to start looking.
Again, Thanks

Without being able to look at it, I don't know what is going on? Battery cables?

Thank-you for your response.
It cannot be the Battery cables because It started
3 hours prior.
I even used Jumper Cables from my car to the T-Bird and still had no lights or anything electrical.
Thank-you for your time.

Anything electrical, just pick a component and track it for voltage and ground. I already told you how to do that.
You never know when a battery connection or whatever can go bad.
Have a good day.

That is exactly what I will do.
I am sorry for repeating my questions.
I will let you know what I come up with.
Thank-you so much!
