The open resistor is not a manufacturing defect. What it is, is a reminder to us that despite the lack of lead in our fuel, secondary ignition components are indeed wear items needing more than once-every-100K maintenance. The rotor doesn't always look like this to give its failure away.

This same open rotor (only apparent with a meter) was one of my first Volvo experiences. What was significant, is I had just acquired a second 240, so the "spare part" was right at hand.

I'm reading a book about anti-gravity. I just can't put it down.
