I have a 1967 Vette with a 327/300. I recently attempted to start the car, and the engine continued to crank after I shut the key off. I assumed that either the starter solenoid fried, or the ignition switch went bad. I purchased a new Powermaster starter, and installed it. Again, the starter would not stop cranking, and I had to remove the neg battery cable. I removed the igntion switch completely, and I still have the same problem. I figure that there must be a short somewhere. Any ideas guys? Thanks,
