Hi All
I have another fault for this type of points that will cause the 0 volt
problem. The insulators become conductors when over compressed, this is best
seen at night, it happened to me and grounded the car for a day, it was
winter so inspection after work was made in the dark, (a trick I have made
much use of before also) I could see the spark go through the nylon, slacken
the nut and voila spark at the coil. The difference was about half a turn on
the nut in my case so it was not really overtight just too tight for the
insulator!
