I installed my new Pertronix Flame Thrower distributor with the Ignitor III and it has a bad hesitation off idle. I am thinking that it is caused by low voltage??? When the car is at idle it is showing very low voltage on the gauge and as soon as I get the rpms up the voltage goes up. It has the original voltage regulator from the poits ignition with the ballast resistor. I have this newer regulator but I am not sure how to hook it up. I tried to just disconnect it and hook up the old wires to the newer one but it wouldn't run.
