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

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!

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.

Thanks Tink. Merry Christmas to you too!

Phil has your one got an inbuilt ballast resistor or do do you still the stock external one or have you bypassed that?

I know what you mean about 6v stuff being hard to get. I could not find a 6v + ground flasher unit anywhere in NZ! Found some good quality Tridon ones through Rock Auto so I bought a bunch of them, they are a great outfit to deal with and shipping is very cheap.

Not using the resistor. Had my resistor mounted near coil for easy access
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.

A touch of mis information as the resistor is not inside the coil. The coils winding is designed so that the primary resistance of the wiring is the resistance . No actual resistor is used ..

flatjack9 · 12-23-2018, 05:09 PM

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.

rotorwrench · 12-23-2018, 06:29 PM

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.
