bottom line, I would expect that you could get the GL1100 coils to work with a points system by adding the resistor, but I think you will have a rather enemic system.
For those trying to understand....
Low resistance coils (of the 0.5 ohm variety) are in this case designed for capacitive discharge ignitions that give a big negative voltage pulse (about -30 volts)instead of grounding one side ofthe coils i.e., instead of just making and breaking the ground (like with points)..
For example, under normal operation at the point of firing, the GL1100 coil sees +12 volts on one side and about -30 volts on the CDI side.. a total of 42 volts across the primary... operating with a points system therecan only be +12 volts and 0 volts, a difference of only 12 volts across the primary..giving less than 1/3 the "umph".. this doesn't mean 1/3 the volts because the coil is designed to be "saturated" so things are not linear.. but it does mean considerably less energy delivered to the spark plugs..
If using a points sytem, you should be using use the 3 ohm coil with the 3 ohm ballast... or in some cases, just a coil designed for the full 12 volts (without the ballast)
