Same Condenser for 12V
I have lots of 12V batteries. Not sure of the ignition. Could the coil and condenser be voltage specific? I may try a blue Bosch coil with a condenser from my old Volkswagen. This is not a final combination, just something to use to run around the yard and try the engine and running gear. I have an alternator and the FSI in a Model A distributor for a plan B. Still leaning toward the blue coil which is labeled "transistor" @ 12V. Thanks: Fred A

Re: Same Condenser for 12V
Condensers and points don’t care between 6 or 12 or pos versus neg ground. Coils are made for the applied voltage. They make a separate 6 or 12 volt coil. Or if you use a 6 volt coil in a 12 volt system, you need a ballast resistor in series. Coils don’t really care about polarity, but the polarity does impact how hot the spark is.

Re: Same Condenser for 12V
You can check your coils w/a good multi meter, the primary winding of a 6 volt coil should be aprox 1.5 ohms, a 12 volt coil aprox 3 ohms.

Re: Same Condenser for 12V
Agree with Bill G. Condensers are not voltage specific between 6 and 12 volt. Coils are specific to the voltage of the ignition system.

Points do care about voltage, they don't want more than 8v to them regardless of battery voltage. Coils care about polarity even though they will work regardless of how they are connected. The polarity should be the same as the battery. |
