Diagnosing Distributor - No Spark Chase

Do you think that I could spin the distributor by bumping the engine over when I'm testing the two wires with the volt meter? I hate trying to take the hold down off.

Sure.
Del and I have different methods of diagnosing, as you probably have noticed.
My ways are side of the road type quick and dirty, and his are more in depth with more precise information. :D

I always suggest a person do the quick and dirty first, and then the more in depth if the problem isn't yet found.
