1952-59 Ford very hot coil

is this essential to have a 12 v regulator?? I did not put on my Ford p***ed in 12v and I have the coil that heats up a lot to make me fall down. Is what would be the cause of all my worries, when rolling she farts very hard as if I was out of gas and then last night she did not want it anymore, the coil was very hot! If this is what it comes from! where to connect the three caps of the regulator? Thank you for yours help !!!

 

Are you using a resistor ? All 12 V from factory used a resistor. If you have a Pertronix, some do not use a rwsisror The are coils that have an internal resistor, but they should be marked as such

 

I do not have a pertronix, my ignition is old, coil 12v 3 ohm, do you think I would need a voltage regulator?

 

because it is not normal that my coil gets so hot???

 

A 12v 3 ohm coil should be OK. I am running a 3 ohm blue Bosch coil on my y-block and it runs fine with no external resistor. I've not had a reason to feel the temperature of it. A failing condenser will give the same symptoms as a bad coil.

 

This is what Ford went with when they changed to 12 volts https://www.ebay.com/itm/284797746711

 

Simply that??? You think it will reduce the heating of my coil?

 

It depends, later on a lot of the coils have built in resistors, you would have to see if yours does. Not really sure when Ford stopped using the external resistors, probably after 1967. Check this diagram out.

 

Ford went to resistor wires rather that a separate resistor. Somewhere pre 64 or so because my 64 Fairlane had the resistor wire. The wire was located under the dash in my 64.

 

This is the coil resistor that Ford used in 56, 57 . I don't know when they stopped using it.

 

Greaser 35, be aware that the ballast resistor gets very hot as well, that is why it is made from a ceramic or steel material. It is designed to get hot, as it heats up the resistance gets higher and reduces current flow more. When the car is idling (low RPM) the points are closed for a longer amount of time so that is when the heat is highest. As RPM increases the time the points are closed (also called dwell time) gets shorter so the resistor (and coil) cool off and the current flow will increase. This is all to prevent the points from getting more current flow than they are rated for and being damaged. I have seen a non resistor coil installed without a external ballast resistor melt a set of points in 100 miles. Mark.
