How to change from points to pertronix igniter 2 wires but what about the condenser. Thanks for all the headliner tips.

The condenser gets removed as well. Pull the points and condenser and the negative wire from the coil. Place in the pertronix and run the negative to the negative on the coil and positive to either the ballast resistor if you have one or the positive side of the coil and your done!
If you do have a ballast resistor..The Instructions say to keep it! There has been a large discussion on whether you need the ballast resistor or not once you convert to the Petronix system. I can't remember the outcome. I kept mine!
I put a pertronix billet dist which is basically the same thing and it said to remove the ballast resistor as it needs a full 12 volts to operate properly but mine also does not use a points style coil. looks like it would work withor without one according to the diagrams in that pdf though.
I am switching to an older style distributor with a smaller cap, Then I got a new MSD Coil and it stated that if you have a distributor with points you needed a Ballast resister, rated at .8 ohm. So then I figured well I am updating to an electronic system with the pertronix 1181 unit so did the need for a ballist resister still exsisit.

So I was going to install a pertronix 1181

Well i called pertronix after reading the instructions on the 1181 it states that you must run a ballast resister rated at .7 ohms and that if you leave the ing key on for more than 30 seconds it could burn up the unit.

I then found out that they have a new model 91181 that solves these problems, that you do not need to run a ballist resister and that leaving the key on does not affect the device it has a automatic shut off.

Ignitor II systems develop up to 4 times more energy between 3000 and 5000 RPM than standard ignition systems. High RPM performance is improved when used with the Flame-Thrower II super low resistance (0.6 ohms) 45,000 volt coil.
  • Adaptive dwell maintains peak energy throughout the entire RPM range, reducing misfires while improving engine performance.
  • Develops on average 4 times more available energy between 3000 and 5000 RPM, and 2 times more available plug voltage.
  • Peak current level is reached just prior to spark for maximum energy without the heat build-up, increasing coil and module life.
  • Adjusts spark timing at higher RPMs to compensate for the inherent electronic delay.
  • Senses startup and develops more energy for quicker, easier starting. Built in reverse polarity and over current protection shuts down the system, preventing component damage.
Just thought that some of you might want to know this info.

ballast removal:

Depends on the coil your using ....

Your coil must be .9 to 1.25 ohms to work correctly...... Cant be a low ohm coil.
your right my dist has the ignitor 2 guts in it which is why I was able to do away with the ballat resistor i just checked my reciepts to confirm. sorry for the miss information. BTW they now sella ignitor 3 which is supposed to be even better! I have had no more issues with missing in the engine which the old points setup gave me. i rebuilt the whole dist and it still missed so in fristration i bought a whole new distributer. I am happy with it but if I had to do it again I would get one of the skip white HEIs off of ebay for 45 bucks.
