Re: Coil Problem
When the points are closed that side of the coil is grounded. Thus, nearly zero volts. In this case, the difference between zero and .07 is just due to the resistance of the wire and connections otherwise it would be absolute zero, but .07 is a great reading. No indication from your voltage readings that the coil is at all bad. If the points were open, your reading would go up to nearly what you have on the other terminal. You can actually check that by taking off the distributor cap and putting a business card or some other thing between the points to open them up. While you are in there, open and close the points with the end of a screwdriver to check for a small spark at the points, and also while doing that put the distributor end of the coil wire near a head bolt and check for a longer spark. You should get sparks in both places. If so, your coil is good. If you try to open and close the points with your fingers, that spark will also give you a bit of a sting-shock. That's why you should use the end of a screwdriver.
