So after cruising around a bit and waiting in a line, the temp gauge got to a little past half way. I got out of the line and the car just died. It's like there's no battery. The clock has no power, no headlights, no warning lights on the dash with the ignition on. The battery is fresh and reads 12V. Terminals and ground are good. I also get 12V when reading the positive battery terminal and the engine block. Downstream from there,I have nothing. The main positive cable is tight on the solenoid and the wires coming out of the solenoid are the same.
I am not getting power to the ignition or headlight switches. It's late and I'm not getting under the car tonight but if someone has any ideas for me to try in the morning, I'm all ears. The car got warm but did not overheat or lose any coolant right before it went dead which may or may not be a factor.
Thanks in advance.

Power is routed from the battery to the solenoid. From the solenoid to the ignition switch is a red wire. The red wire T's off to the fuse block also. 

You need to check the battery cable going to the starter for shorting out.  Then check the red wire going into the car at the round rubber block at the fire wall. 

Just a little side story; I was on a first date with a las when i was a very young man. The car suddenly shut off and I was able to coast the car to a parking spot, and rolled the car up onto the curb so I could get under the car.  The positive battery cable shorted onto the frame at the adel clamp, completely burning the cable in half. 

This was back in 1989, so no cell phones were available, and I was new to my new military base and had no friends to call upon at the time.  

So, the gal called her mom and we went to the parts store to get a battery cable. 

Needless to say, that is not the woman I am married to today. 

I , too , was on a first date , drove to the wildlife refuge and parked for a while. Mostly just talked and it started raining ,didn't rain hard or long. Got ready to leave and it was now dark. Turned on my headlights and nothing ; no lights inside or outside. Made it home safely and no ticket. Next morning , lights worked fine ,has never happened again since. Still own the car , my first , over 40 years later.

Thanks Russ, The ring terminal on the 10 gauge red wire was still crimped solid but it seems the insulation had wicked in due to heat, probably not just from last night, and was causing a complete short. Replaced the terminal and all is good. Checking the old one, even with the solid crimp, there was no continuity at all between the wire going in and the ring connector. I knew it was something simple. A soldered terminal is probably a good idea here and will do that shortly.

Check the block of wires on the firewall ,sometimes corrosion can cause problems under that block of wires there

Sorry for your inconvenience but glad it was such an easy fix with help from Russ that had a very good idea of  the cause from his experience 

Enjoy

My 1964 Cadillac electrical system is running around 17 volt which is to high,the alternator, battery and the voltage regulator was replaced but the voltage is still to high, could it be the pig tail that plugs into the voltage regulator.
