Thanks for all information~~~~~Ron
We had a kent moore module tester back in old days at the dealership. You can also ohms test the coil. More often than not the problem was the pole piece and you have to remove the distributor to replace it anyway. In my personal car I used to always carry spare point type distributor, resister and jumper wire. It saved me more than once.
