I guess it's the way the world is going. My parts places are old school type places with some equipment, I think one of them still turns rotors.
What one can do is hook a multimeter and if it has memory (lowest voltage) even better. Have someone crank the vehicle while monitoring voltage. If it dips below 10ish it's toast.
