My 1975 Chrysler repair manual says the dual circuit ballast resistor should be .5 ohms on one side. I measure 1.5 ohms on my samples and the replacements that I find are also advertised as 1.5. I see that Accel advertises a .5 ohm dual circuit resistor. Should I use that one with a stock coil and ignition box? My car seems a bit livelier when I hot wire the coil.
