And if there is voltage at the + terminal of the coil (measured to 
engine ground) how much, and does it change as you open and close the 
points? Also does the voltage measured at the - terminal of the coil 
change as you open on close the points? You can open and close the 
points by a screwdriver (open them if closed, short them if open) or 
bumping the engine with the starter. DO not try turning the engine with 
a wrench while doing this test, just in case it starts!=-O

I would have done the voltage measurement first, before changing any parts.
