Default Mallory tech answer to coil/ballast ?

Reply from Rep:

You need around 1.5 ohms on the primary of the coil. This is between the key-on 12 volt source and the negative side of the coil. So either internal in the coil, loom resistor, and/or ballast resistor adding up to 1.5 ohms is required.

Ok, thanks for the help. The new Mallory electronic coil states not to use a resistor so it has 1.5 ohms?
Reply from Rep:

coil #29219 has the resistance value built in, so no external resistor would be required.

Just got this response today from Mallory about the electronic coil and the correct 1.5 ohms. So it looks like for the last 6 years I have not had to use the ballast resistor. The next question is, how will my system run with a full 12volts, better, hotter spark? cleaner plugs, faster starting?
