The original Ignitor is a stock points replacement, that is all it does. (and it does it very well too!) The Ignitor II has a microprocessor built into it that helps maintain a better dwell curve at higher RPM ranges. I think they say above 3000 RPM is when it becomes usefull. If you spend most of your driving at "normal" RPM ranges, the Ignitor original is probably all you will need. If you are after more performance in the higher RPM range, then the Ignitor II may be a better buy for you.
You can't go wrong with it. I've put the original Pertronix in cars, trucks, boats, tractors and my road grader. I love them. They only thing you have to really watch for is to make sure there is enough voltage going to them. Some engines (many actually) use a resistor wire to the points to drop the voltage down to decrease point burning and pitting. You should meter the voltage to make sure it falls into the correct specs for the Pertronics. I don't remember off hand what that is, but I think it is anything above 9 volts at the distributor. On a couple engines I converted, I had to run a new wire to get switched battery voltage at the unit. No big deal, and it is all covered nicely in their instruction sheet. They also have a toll free line to their tech departmant that will help with any questions you have on installation. Eric J
Igniter I is much more tolerant of lower voltages to it than Igniter II. There techs say II definitely needs 12v, so you have to bypass your resistor wire. I is tolerant of down to 8 volts.
Pertronixs I have used the igniter#1 in several cars of mine including the 72 mav I drive now...I love it.it does a great job...Jim
I have had the Ignitor ll in my car for over 3 years, and it has been flawless. Best thing I did for the car.
Not to spoil this threat, but why even run points/petronix? I dont know the price but I think they are around 45 or 50 bucks? For that price i got a electronic distributor, and a duraspark box. very easy to wire up and its electronic. Just curious as to why you guys run these. I converted my 66 F-100 w/ 390 over to Duraspark for less than 30 bucks Bought new dizzy, took old one in as core, and had a duraspark box here already. But the box is only 12 bucks or so. Not trying to say what you guys run is bad, just curious as to why you run them
I like the stock look, as all you are changing is under the cap. No added box. No need for an HEI coil either. JMHO
I ran my old truck w/ the stock coil w/ duraspark and had no problem with it. I did convert it eventually to a Blaster 3 tho
hmm... I must have a really old Pertronix... Mine required 6v. Had all kinds of cautions about 12v usage and requires resistor...
Different, the magnet that goes on the distributor shaft has eight "corners" for a V8 and six "corners" for a 6 cylinder.
