I checked my coil voltage with two different volt meters and got 7 volts starting and 4 volts running. I tried a different ballast resistor and got same readings. I clipped meter leads to the two coil post. I think the coil is original, so may be 34 years old. (They don’t make things like they use to.) In earlier posts it says it should be 12 volt starting and 7 running. I replaced the coil with one from auto zone and I get the same volt readings. I don’t know if I am checking it right or what is going on.
