Pertronix and then
« on: March 18, 2019, 03:30:30 »
Well, I installed the electronic ignition, changed the coil to the recommended coil, changed and gapped plugs5 thou more and installed new spark plug wiring - could not get car to idle well , but reved fine.  Noticed that I may have chipped the magnet (1864) so changed back to points, while I try to order a new part.   Need to get car running so I can get it to the body shop.   My question(s) - 1. I reinstalled the points and resistor, but not the plug wires, plugs and coil.
Car started fine, and idles well,  If i leave everthing as is, will the points burn out and will I damage anything else?
2. On the coil side, postion 1, goes to the points and I had a green/black wire on it also.  seems to make no difference if it on or not.       
Thanks for any info,  this site has been very helpful from trans shifting to window replacement (another story)

Do you have the aluminum distributor? You should hook everything up the way it was with the points coil system. If you changed to a hotter coil use the stronger ballast resistor.

It's not recommended to JUST change to electric (Hall sensor) points, there will be interference in the  Petronix:
1. Petronix Hall Sensor
2. Petronix Ignitor Coil
   a. Remove Condensor
   b. Remove Ballast Resistor
2. NOT use Factory style Solid Core Wires (Bosch, Beru & Kingsborne reproductions)
3. WR (Resistor) Plugs (to further reduce any interference with Petronix system)
  a. Also allows you to open Spark Plug gap an additional .007"
