What if there is no spark from the coil on a 1963 Chevy Nova?

Answer 1

Ok. Some of the early Chevies do not have a 12 volt source for the coil, in the cranking mode. You can run a wire from the selenoid, to the coil. If that does not help, then, you may have a ballast resister, mounted on the firewall. It would have been white, at one point in its life, rectanglular, with a triangle in the center. There will be two terminals. One on each end. These burn out, and they are cheap to replace. Coils, themselves, very rarely go bad. I have never experienced a bad one, in 30 years, and have only heard of a bad one, once. However, I would not rule that out, as a last resort. Get a test light, and see if you have 12 volts to the coil. If so, then it may be bad. Chances are, your not getting 12, to the coil, in which case, one of the first two rememdies, will work.
