tr3a 1958

    TR2/3/3A 58 TR3A Coil weak? 9KΩ on the secondary with a 1968 HA12 45208A non-ballasted coil.

    A friend has a 58 TR3A. He had some warm no start issues (let us not talk ethanol and heat soak). I thought possible could be the coil getting too hot increasing resistance and lowering the high volts delivered to the plugs, and adjusted the voltage regulator shutoff down a tad 1/8 turn...
