Morning all. Can anyone tell me the correct resistance for my ballast resistor. 57 272 with Pertronics conversion. The porcelain is cracked and one terminal is loose. Thanks
Greg; I may be mistaken but as i remember you don't use the resistor with the Petronics. I do however think I have a couple of correct resistors if needed. Tom.
I installed a pertronix kit in my 56 T-bird 312, I also replaced the ballast resistor with a generic one from the local parts store it is 1.4 ohm been running fine for about 4 years now.
You need the ballast resistor if using an original coil. If you use the Pertronix coil it has an internal resistor.
Thanks for all the replies this gets me on the right track.
