Well I gave you a lot of information there but it is very simple. Touch the two terminals and divide that number by 12. Done.
That sounds like a great trip. I expect you will get a lot of waves and honks. People love seeing these old thunderbirds (which you don’t see often).
Hey I forgot to mention very important, check the positive ignition wire that feeds power to your
coil, sometimes they used a resistance wire to drop the voltage to the
coil, negative to the chassis and positive in the wire, if it is lower than 12volt you will need to take that into account and divide by that voltage and not the 12 volt I originally told you.
I believe the newer Pertrinix handles much more power that the 6-8 volts mine handles do I expect your under powering your spark if you have both
coil and resistor.
I did not want to run the
coil and resistor because it’s just less to go wrong, so I went to
Napa and checked resistance on multiple
coils and found the correct one (for my setup) with the 1.5 resistance. All
coils and resistors are different and offer a wide range of values so you can often find the right
coil by testing them. They don’t all have the resistance written on the box. Just make sure you get the one with the screw posts and not the clip style.
I went with the
Napa brand because I wanted a
coil that was easily accessible if it ever burnt out (which you will if you ever leave your key on without the motor running) mail ordering the
pertronix suggested
coil is not always going to be an option and I personally feel it’s the same
coil everyone else sells but has their sticker on it so don’t feel pressure to buy the ones with the fancy name.
Ok good luck, and have a great trip.
