In another thread a few guys were talking about converting an old point system over to HEI. What I done in my 1968 chevy with a 327. Is took out old point Dis. And replaced it with a HEI dis. Don,t knnow what it came off of. It,s the kind with the coil mounted on top. Everyone was saying the old point dis. has a 6 volt wire going to it. And that it may have a resistor built into wire. The wire on my truck has no resistor on it anywhere that I can see. And I have been runing the HEI dis. for a while. The truck seams to crank and run okay. I want to check the wire to see if it has 12 volts. But don,t know to use a volt meter. Thier is one around the house however. But I have never use it before. How do you connect it up? Also, could all this have somthing to do with the volage Reg. or Alt? Thankss, John.
