Using Points Distributor with non-factory wiring harness?
Anyone have a suggestion on how to safely wire and set up the reduced (<12V) voltage level needed for a points set up when I only have 12V available? Factory wiring harness is not available in the car and I want to use the points system to run a points compatible tach. Thx.

Easy. You use an "old school" ballast resistor. I know MSD has them.

well - I figured there was an easy answer. Thank you! I was going to get the abacus out and do some engineering calculations but that might have resulted in a car fire.

The original points wire harness had a full 12V to the coil during cranking to give a little more juice for starting a cold engine. If you have a hard starting problem a separate 12V wire from the ignition switch to the coil might be needed.

The R terminal on the starter solenoid was designed for that.

Or you may use the SMP RU11 resistor. It has .50 - .60 ohms at start and 1.75 Ohm while driving. No extra wire from starter needed.

I've always used a Mopar resistor with good luck. Use the early style. The later ones are a double resistor. You can usually get one at any good parts store for cheap money.
