No electrical in car.
I have a 1980 L82 that has no power inside the car, no nothing. Have 12 volts at the starter, and alternator. Both fusible links at the starter look good with no discolor. Have 12 volt power up to the first plug connection by the distributor. Ground cable is new to a clean frame Read a lot of threads on what it could be , probably the firewall connection or maybe fuse box . My question is , to get me to the garage , now setting on the back yard lawn , could a jumper wire be ran from the battery to the fuse box get it started for a quick fix? Maybe ?????

I'm not super-versed in electrons, especially for late-C3s... Do you have all exterior running & brake lights? If not I'd suspect the firewall connectors (there are 2 on the engine side that are conjoined) On my '72, there's a bolt from the engine side that helps secure it them place; pretty easy to check from underneath if they are firmly seated.

power wire from large terminal on the Alternator to the batt terminal on the distributor . Then it will run. Jump the starter at the solenoid. Make certain car is not in gear when jumping starter solenoid.

OK guys this is what I done to get the car started and out of the back yard. This might be helpful for others. I clipped a jumper wire to the positive battery post, ran the wire up to the fusebox. With a spade connector on the wire end , inserted into the fuse box hole with the letter V . V must stand for VICTORY as it powered up the box and the car started and drove to the garage. Probably could have driven it for miles. Now to find the problem. thanks For the input .

Unplug the starter extension harness where it joins the main harness near the wiper motor, and test for 12V there. That is still the most likely culprit, and the easiest to replace (just throw $80- at the problem).
Starting in 1980, the alternator charge lead connected directly back to the battery, so it makes sense that you have 12V at the alternator, starter, and battery.
Here are wiring diagrams, if you need them.

That I did not know. Do you have a reference for that? The only wiring diagrams I have handy show the wire, my 80 has it (but didn't come with the stock radio), and my assembly manual is far away.
