Default Re: Car Will Not Start--No Apparent Spark

The fuse is good. When removed and held to negative battery terminal, the multimeter gets 6 volts to the positive battery terminal (through the fuse).

With the ignition switch on (popped out) and the fuse removed, I get 6 volts to flywheel side of fuse holder and 0 volts to the radiator side of the fuse holder as expected. I also get 6 volts to both sides of the coil and 6 volts to both junction box studs. The movable point arm has 6 volts, and the stationary point arm gets 6 volts, which doesn’t sound right.

With the ignition on and the fuse in place, I see the following changes. I don’t see any voltage on either end of the fuse (while inserted into its holder), and the passenger side junction box stud drops to 0 volts. All of the other cited measurements are the same.
