The Ford Barn - View Single Post - Resistor Unit / Coil Resistor 6 Volt System

I believe the Bosch Blue was recommended if I had a 12 volt system ?, but for a 6 volt system the 3 ohm will be to much ? (only 2 amps on 6 volt)
Further research indicates that the coil resistor is only needed if using an "original" pre 48 coil that has an internal resistance that is less than 1 ohm (maybe 0.8?) But if using a regular "round can" coil no coil resistor is needed, just a 1.3 ~ 1.5 ohm coil typically referred to as a 6 volt coil (or 12 volt coil that needs an in line resistor.)
