coil question
If I was to run a cylindrical type coil on my car what type should I use?
It is a stock 6v ignition system that runs through a resistor on the circuit breaker board on the internal firewall. Thanks GB

Re: coil question
Stock 55ish up ford to 61 I believe (in trucks) without a resistor. Early y-blocks had 6v coils on 12v battery. Ceramic resistor to get down to 6v and internally resisted (1-2v if I'm correct).
Merry Christmas! |

Re: coil question
Some folks say the Bosch blue coil for 6-volt VW is good but I hear that they are silver now. It depends on what's available to you in NZ. It's getting harder to find good ignition components here in the US so I can imagine it may be more difficult where you live. A can type coil with a primary wound for 6-volt should need no ballast but one wound for 12-volt would need around 1.5 Ohm value ballast resistor.

Graeme, Recently fitted a new type 6v round coil. I purchased it from Michael Driscoll, 3rd Generation, hes on this site. i am happy with it. Looked in NZ but could not locate a new 6V one. I believe the 6v VW coils could be used. Phil NZ |

as went through a stage of back and forward with original coils and new type ones. Engine has just over 500mls on it and this was the new coil as fitted from 3rd Generation. Its all good. Phil NZ |

Re: coil question
In 49, Ford did away with the resistor, so a coil from that era can be used if you bypass the your resistor. Either that or find a coil with about .75 ohms resistance and keep your resistor.

Re: coil question
Yep, it's all about the design primary coil resistance. It's getting hard to find new stuff that gives you the primary resistance value specs now days. The only coils that had a resistor as part of the coil that I can recall were those old Echlin Bear Ballast Wizard 1300 coils that had the light bulb ballast resistor screwed into the bottom or top depending on how it was mounted. They were popular back in the day but I don't know how effective they were. This is a link but the tractor guys didn't know what it was.
