Testing distributor
How does one go about checking the distributor? I need to find out if it is getting power. Where does the power enter dizzy? Where is the ECM located? 1985 z28 with 350/TPI automatic. There is no external coil on this engine. What would be the proper pickup coil resistance? If the resistance is right can it still be an issue?

If you have a HEI dist with the coil in the cap then the Ign power wire is the pink wire to terminal on side of dist cap
should have 12V on it with the key on
