Ignition coils

you can use the Pertronix with a 1.5 ohm coil as long as the coil is being fed at least 8 volts, according to what they have printed on the product container.

That rating is for the Pertronix module, not the coil. Pertronix instructions are quite clear that the module should not receive power through the resistor.

I have those instructions; they it apply if the ballast supplies less than 8 volts to the coil. I know there are engines that get less than 8 volts to their coil and they should follow those instructions..

Suit yourself. But I know from experience that the Pertronix module will not work properly on much less than 8 volts; and since the battery voltage can easily drop to 9 volts when starting on a cold morning, I certainly don't want the ballast resistor dividing that down before it goes to the module. So I'll continue following the installation diagram, instead of the troubleshooting instructions; and advising others to do the same.
