Does anyone know what kind of ohm reading a good coil will have? How do you check the stator? How many volts should it produce? I think my ignition is breaking down at high rpm. Any ideas?

For the primary ~2-3 Ohms would be about right. Never checked secondary but probably 10X that.

Intermitant failure on coils does happen but it is less common then a dead coil or [plug, points, capacitor, timing, carburetion] type misses.
