My old 7al-2 box is in a friends car. 20 years later, still works like new money! The old stuff like this seems to be MUCH better quality. Or it's just so much simpler it doesn't have all the sensitivity. Dragula...I did try another coil, no change. As well as unplugging the tach, new crank trigger, and new trigger wire.
