Read several posts dealing with ballast resistors, and I am not quite certain I need one. I have a 55 12v second series motor in my 55 1st series truck. The coil reads," no external resistor needed" although it is still connected to one. It has been wired that way for some time now, and after reading up on it, not sure I need one. Stock distributor and points. Thinking of going the Petronix way though, but that will be in a few months or so. Any harm having it wired as such?? Appreciate the help! Kato
