Normal voltage while the car is running should be between 13.5 to 15.5 volts. 12 volts when the car is not running is also normal. I noticed you are using a duraspark ignition. What are you using for the controll module? The reason I ask is I am having a little problems with getting my ignition wired up. I am using a MSD 6AL and wired it up per instructions and have no power at the coil with the key on. I am also using the painless wiring harness. If you can help out that would be great.
Thanks, Ray
