Just got done putting my interior back in my '66 Coupe (302) after an interior rebuilt, heater box rebuild, etc. Car unfortunately sat for 3 months.
Tried to start it yesterday and battery was dead- took it to be tested and the computer stated replace. Did so. Almost like it was a spark problem. Cleaned everything changed the petronic oil-filled cylinder where coil connects to) back the the stock one ajnd it fired right up.
Its less than a year old. Do you think that was the problem? Has this happened to anyone else? Thank you!
OK, I'm not sure what you are describing regarding an oil filled cylinder. Let me assume something( I know, I know, LOL)here---The coil Is an oil filled cylinder, so I assume that's what you're talking about. If not, let me know. Now, to put your mind at ease, The pertronix is a solid state part- it either works or it doesn't!! there';s no in between. It simply can't work "sometimes". once it quits, it's toast!!! If you got it running again, the pertronix module is A-OK, period. I think you replaced the coil (the oil filled black cylinder that as two electrical terminals and one larger terminal where the "spark plug" type wire connects to the distributor cap center post) . Is that correct? If that's what you did and the car is now running, then the coil was bad and, since you replaced it, the problem should be solved. if I'm wrong, write again and we'll try to figure it out.

I don'i know Jay, he said "Oil Filled Cylinder where the coil connects to". I don't know what that part could be either!
Silverblue66, Jay is right, a
Pertronics either works or it's bad. Yours started after you got the new battery, so it must be OK. But what is this "oil filled cylinder" that you say connects to the coil? Are you using some sort resistor? Are you refering to the coil?
A Mustang Pertronics only connects to the coil and the ignition wire.
The only oil filled cylinder on a car ignition system would be the coil.
Thanks everyone for the quick response. Yes. Its the coil. 'Flamethrower II" its called. Thing is less than a year old! Boy, did it feel good to her that engine come alive. Couls be worse!!
The coil could very well have gone bad, it's a man made part, it could last a year or 10 years.
I have the Pertronix 1 (original one, not the 2) and running it with the repro "yellow top" coil. Haven't had any problems since installing it in 2004. I thought about upgrading to a Flamethrower but it runs fine with the current coil and for what I use the car for there wouldn't be any benefit for me.

Trying to find my father's 1973 Mustang Grande he bought brand new. 3F04F126773 last known registration and title was in New Jersey, 1982.
I'm glad to see your ignition woows solved. For me, installing a new Flame-Trower II coil and Ignitor II billet distributor solved a lot my ignition problems/mysteries. Although, it's a stray from the original looking equipment, I'm glad to put the inconsistent ignition issues behind me. BTW, beause I can't quite get the timing and fuel right on this old 289, I'm thinking about rounding out the Pertronix suite with a Second Strike module as well. Couldn't hurt to burn off that residual fuel.

I installed the Pertronix II & a Flame Thrower coil in my 66 and I don't know about it either works or it doesn't. 1st day ran great, 2nd day the car started to miss real bad. Check the gap .30, still missing real bad. Put new points and condenser in and the car ran fine. A week later the car died while my daughter was driving it. Put the original coil back in and it's been running great for the past few months. I know alot of people on this site have had good luck with there Pertronix system, not me, I staying with the points.
The Pertronix has to be aligned when first installing it or it won't work correctly. From what I remember I think they give you a little piece of plastic to make sure you have the right "gap". Also, the Pertronix seems to have a little trouble working with the stock inline resistor on the vintage Fords-mine would just cut out sometimes and wouldn't let the car start again for 10 min or so. I never did cut out the resistor because I didn't want to butcher the original wiring harness and I never tried to bypass it with a direct wire but I wasn't happy when it occured.
The little plastic thing is a tool to get the right gap, used that and check that several times. My car had no problem starting. Was the unit defected ?????
Bob A- it could've been your coil that wasn't responding well to the pertonix and when you replaced it it was fine. Try putting the prtronix back in and see if it OK now that the coil has been replaced. Could also be that your car was having the same resistor problem as mine did.
I don't know about the pertronix II but the original replaces the points and condensor. there is no points to replace. having said that when I put in my pertronix ignitor with the original coil it ran great for years. I decided to upgrade to the flame thrower coil just because the original coil looked bad. since then I have had problems with the rotor and cap burning off a bit and needing to keep a spare rotor in my car. I considered going back to the original coil but I finally decided to just replace the distributor with a digital ecurve from msd. works well so far.
