Yes, Pertronix sells two different resistance coils for use with the Ignitor 
I (note that the Ignitor II is completely different and is designed to use a 
special coil). The way you tell which coil you have and need is this: Use a 
quality digital ohmeter (DVM), Measure the resistrance of the primary winding. If 
it is 1.5 ohms or less (i.e., between 1.2 and 1.5) then you have a coil; that 
is designed to be used with the stock ballast resistor. But if your coil has 
a primary resistance greater than 1.5 ohms (nominally 2.5-3.0 ohms), then you 
should bypass the stock ballast resistor to get the full 12 volts to the + 
terminal.

So looking at the above in reverse, if you want to leave the stock ballast 
resistor in the circuit, then you want to buy the 1.5 ohm coil, and so on.

FYI, the 1.5 ohm coil is sold by Pertronix as the coil for 8-cylinder cars 
and the 3 ohm is sold for 6-cylinder cars. But you should pay no attention to 
this and use the above description to make your choice.
