12 volt coil Anyone know what car and what years 12 volt coil could be used without a external resistor? Converting an A to 12 volts and do not wish to use an external resistor.

Re: 12 volt coil BOSH #00012 blue coil. Look on Amazon. They work great.

I agree with the unsightliness of the external residtor on an A ! The way that I dealt with this 'problem' , is to use a 12V coil with an INTERNAL resistor (built into coil). Been running coil this way for many years...no problem. Good luck. |
Re: 12 volt coil Any 3 ohm epoxy filled coil should work
|
Re: 12 volt coil Check out the 3 ohm coils at First Street Ignitions. I would recommend an epoxy filled coil.

There is so much confusion on the collector boards about ignition coils, they need to be measured between terminals so the user is certain of what he is installing. The resistance is what determines how much current (amperes) flows through the circuit. |
Re: 12 volt coil you might be surprised what's inside a 12V coil

Exactly..........and another good reason to stay with the original 6 volts. |

"Coil: you'll need to get a 12v coil with internal resistor. Again, available from the A vendors, although I got a suitable one at the local parts house. Showed them the 6v coil and said “Match this size.”. They did. Turned out it was an Airtex coil 5C1019. A little sleuthing on the 'net revealed that it was used on several foreign cars, 1974 Volkswagen and 1975 MGB and perhaps others as well. This is a 12V coil with internal resistor, and it has worked very well for the past 2+ years I have been running it. When I first made the coil change, I did not have Les Andrews' books. His recommendation is a UF-3 coil with internal resistor. (You really need to read Andrews' book. I did and it has helped immensely.)" |
Re: 12 volt coil My wife's 1961 Morris Minor uses a 12V coil, no external resistor.

He indicated that he didn't want to stay with 6 volt system and asked about help with 12V system..no ? |
Re: 12 volt coil Quote:
bad and then make my decision. |

Hey Chuck, Did you get the help here that you were asking for ? If not please give more information so we can help you ! If you feel that you got requested/needed help, that is good to know. BTW, I probably know of several reasons why an A owner may want to change from 6V to 12 V, but would you please give your reason(s) for changing ? |
Re: 12 volt coil The reasons for switching to 12 volt on my touring cars is to allow installation of air conditioning, use of modern 12 volt accessories(Nav, cell phone charger ,sirius radio, etc.), consistency with all of my other A's (have 6 - all 12 volt), easier to start (my opinion and experience), and easier to more safely jump start from or to a modern car.
Are there any domestic cars that ever used a 12voly coil without a external resistor? |

Re: 12 volt coil OK, switching to 12 volts to add air conditioning makes sense. If you just need to charge or run cell phones and GPS, mine both work fine on 6 volts. Also you can buy convertors to change 6 volts to 12 volts. I bought one because I might use 12 volts on turn signals if I install some.
