edhd58 Posted January 24, 2015 Share Posted January 24, 2015 I can not find a 12 volt ignition coil that is original appearing to my car, 1942 Ford --6 cylinder. My question is can i drop the voltage to the ignition coil to 6 volts so I can use an OEM coil and wiring? How do I do this if it is possible? I have checked many vendors, what I have found is I've been told Dennis Carpenter was the last to make these. I spoke to Dennis Carpenter and they say they don't carry these anymore. I know I can go after-market but I don't want to. That is a picture of the OEM style coil Link to comment Share on other sites More sharing options...
Rusty_OToole Posted January 24, 2015 Share Posted January 24, 2015 You could use a Runtz, resistor, or zener diode. Lots of newer cars used a 6 volt coil on 12 volts, with a resistor. They were wired to give a full 12 volts for starting and 6 for running. If you want it to be invisible you could use a GM resistor wire. Link to comment Share on other sites More sharing options...
rsb Posted January 24, 2015 Share Posted January 24, 2015 Yes, it can be done but if originality is so important why not change the electrics back to 6V and run the original style coil? Link to comment Share on other sites More sharing options...
edhd58 Posted January 24, 2015 Author Share Posted January 24, 2015 41-47 Ford Ignition Coil 12 volt with Script,Ford Licensed Product 1GA-12024-12 <!-- DO NOT change linkToTagId="rwid" as the catalog response has this ID set --> Just found this on E-Bay, two were available so I got them both. If they are this hard to find and no long made I want a spare. I can not believe just 10 minutes after I gave up hope of finding one I find two.
