New member here. Also new owner of a very used 70 vette. I am having trouble with the points and condenser ignition system. There is no spark at the plugs nor from of the secondary wire of the coil to ground. After reading the threads on this topic, I believe my problem is that I am getting 12 volts through the primary wire to the coil and this is causing the coil to fail. After reading various messages I learned the voltage should be around 6-8 volts. I checked the voltage at the positive terminal of the coil with the ignition switch in run, there is 12 volts at the coil. There is also 12 volts at the primary terminal on the points. Today I purchased and installed a ballast resistor (vs new resistive wire). However, I am still getting 12 volts at the coil. I am on my third new coil. I have also installed a new set of points and condenser. Note: there is no wire from the starter solenoid to the coil, just the primary wire from the ignition. Any suggestions? Thanks.

when you removed the old points, did they looked burnt or pitted. did you set the points at there proper gap. the point dwell with the engine running on GM's is usally 28 - 32 degrees.with a dwell meter. remove the coil wire from the distributor cap and crank the engine if you get fire you may have a bad rotor button or a bad cap. on the point distributors the lobs on the distributor get worn and will not open the points properly. and also check too see if the distributor is turning when you crank the engine, if it does'nt move remove it from the engine and check the roll pin on the gear ,too see if it is cut off repair if nessary, if ok you may have a broken cam shaft or a broken timing chain.

Thanks for the advice. It appears the new points I installed were actually defective. They appeared to not open and close properly and the dwell adjustment screw would not turn. I returned the defective points and installed another new set of points and the engine started. Thanks again - 70 blue vette
