Anyone know where I can get a book on automotive scopes for points and electronic ignitions? Maybe even a website that has some educational info? Trying to chase down a miss and I've had this scope sitting around. I know I could do the hilljack method and pull one spark plug at a time and look for RPM drop but I want to learn to read the scope.

thanks always!
John

That's a lotta volts for a direct O-scope hook up. They sell probe attachements that clamp on, much like a timing light, and sense current and give a converter voltage. You would be looking for a square wave with space between repitition being proportional to RPM.

Or you could just use a timing light

Or you could just buy new points

Or you could buy a new cap.


sheesh, it's always about buying stuff!!

Mike, wrong scope!
I have a sun scope that I need to figure out how to use.
I know what your saying about a standard scope, that would not be cool!

thanks
John
