Use an older analog ammeter and see what you get. Cheap digital meters do not always work very well on old cars unless it is a higher quality Fluke or such. I think 4.5 amps is on the high side and would be good at around 3 amps. Many cars I have tested are down towards 2 amps with the engine running. Engine running with the points rapidly closing and opening the circuit regulates the current to that lower figure. The higher the current draw the quicker the contacts burn out. Why do you need a FLAME THROWER coil? Half of its potential output would never be used on your engine. Use a standard ignition coil. Regards, Kevin.
