Can some one explain to me whether or not you need or use a ballast resistor with an HEI and alternator. I didn't think so but a good friend of mine who is more of an auto electrical guy says they are sometimes needed in older cars that have original wiring...he said it helps distribute the load on the electrical system?:confused0006:
I seriously don't know squat about what a ballast resistor does or doesn't do but my friend seems pretty confident in his assment?

BTW I do have an HEI ignition and distributor and an alternator on my '55 and a ballast resistor.

??????.

You do not need the ballast resistor. It just dropped the voltage through the points. Without it points burn up fast. The starting circuit bypassed it anyway when cranking so you would have a hotter spark. It doesn't do anything in the rest of the electrical system.
