"When using the supercoil with stock Chrysler or Ford Duraspark systems, use the ballast specified by the manufacturer..."


1.5 ohms seems high to me, looking in my 73 FSM you should have a .50-.60 ohms ballast, not 1.5 ohms.

They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
