66 valiant no start

Probably a bad condenser
I was surprised to see how inexpensive condenser and points are. I tried to do the test that 67 was talking about and had 12. something volts to the starter and 11.6 at the coil while key was on run and when I started bumping over the motor it went down to 6v and then the battery died again. I'll prob. replace points, condenser, and battery for now. It has a new ballast on it already and now a working coil. Fingers crossed but always happy to hear feed back and learn more. Thanks for the post valiantwagonguy.
