383' shuts off' issues, I tried praying, no luck

Next time it shuts off Don't touch a thing! Measure the voltage at the coil + terminal. You are looking for about 7 volts.
If Zero, move up the line to wherever the voltage reappears and BINGO!
But If the voltage is there, then pop the cap and turn the engine to open the points.Take a small screwdriver and short the points to ground in a stabbing motion so that the short exists for only a split second. You should see a bit of sparking going on, at the tip of the screwdriver. And you may hear the sparking inside the cap as the coil discharges into a wire. You could pull the coil wire out of the cap and near-ground it to see the action.If no action, the ground circuit inside the dizzy, from the point plate to the body may have failed. You can put a jumper wire on your screwdriver and the other end to a good ground and try the sparking thing again. If in now works, go fix that internal jumper. But if still no worky, then you will have to prove the condenser is good, and properly grounded in its holder.Go turn the key off. Disconnect the condenser. Go back and turn the key back on. Try the screwdriver thing again. A spark now means either the condenser is bad, or the circuit came alive at the key-off/key-on cycle. I would replace the condenser, install it properly grounded, secure the ground jumper and put it all back together. Then start the engine, and see if it stays running now.
If it quits again, at least it has nothing to do with the dizzy now.Go back to; Don't touch a thing. Check the coil for voltage at the + terminal, as before, looking for about 7 volts. If it's there, then pull all the wires off the minus terminal, and check the voltage there. Wait! By any chance do you have a tach hooked up there? Well disconnect it! I shoulda thought of that first. Yeah so put it all back together, I bet no more problems.
But if no tach, how much voltage should I be looking for? I got a brainstall. But if zero there, throw the coil away, it's gone open circuit. Ima gonna guess there should be a half a volt or so less on the minus side as on the plus side.
Del? you there? Help me out
You can check the coil out with an ohmmeter. It should have less than 2 ohms, more than 1/2 ohm, through those two terminals and 8000 to 10,000 between the coil minus and the center tower.This is a general number.
