Looks like a good repop part. There's an error in the instructions, though: "When the switch is“off”, the, coil is isolated." When the switch is off, the coil is continuously grounded, and will short current to the coil hence no spark (note the 'C,' 'B' and 'C-B' circuit labels). This is for points, if you have a Pertronix--I'm not familiar with other electronic ignitions--the wiring will be different.
