Phil.. 3 ohm is a standard primary value for a 12v coil. You can buy off-the-shelf round can coils likethis.. the NAPA IC14SB The square coils that are labeled as 12v are about 2.5 ohm coils.. thus the need for the 1/2 ohm dropping ressitor. The oem ballest resistor is for use with the 6v square coil. If you run the 6v square coil on 12v, you need the oem ballast resistor, and a dropping resistor like the 8ne10306. Do some online research.. It's easy to find graphs showing coil ohm values and the resistors used to make them work. They all fall at 2.8-3.2 ohms... Putting 3ohms in the middle.. etc. Soundguy
