Car will not start will crank and crank. You will also have no spark. if you put an MSD box in you can eliminate the Ballast.
You will get a similar symptom when the fusible link goes bad.- crank but no spark. I have found more fusible links fail than ballasts, but the ballast does fail from time to time.
The main fuse link kills ALL power. No dome lights, no park or head or tail lights, no nothing. Only way it would crank on many years is if you jumper across the starter solenoid
