| Currently looking into 6 to 12v conversion kits, which changes generator to alternator. Do i also need to change my spark plugs ? If so which ones should i buy the car is a 1966 1300cc 50hp. |

| No, but you need to change the coil |

If I were you, I'd get my phone and call an Automotive shop and ask them if they sell 12 volt spark plugs. Please post the answer you get here. :lol: |

| 6 and 12V are both junk, get the 10,000 volt ones ! |

| I was talking since plugs have resistance, if i have a higher voltage now i could use sparks with different resistance in order to get a higher efficiency |

Quote: since plugs have resistance
The rotor button and ignition wires both have resistance built-in too.
One reason there is resistance in the ignition 'system' is to 'block' ignition noise from being heard on the radio. Also, the resistance determines the strength of spark that can manage to jump the gap. If the total resistance is reduced by either reducing the electrode gap or putting a spark plug with lower resistance, a spark will jump the gap before building to formidable strength.
You can also put a ballast resistor on the power lead wire #15 to the 6v coil for use on 12v.
Best advice, get a 12v coil. |
