I remember in the old days, working on cars with the old fashioned mechanical breakers, that had to be changed every few thousand miles. They worked fine (until the contacts started pitting), so I would have thought that in this day and age, someone would have come up with a cheap solid state version that would do the same thing, but in a better way. :??:
