Well I feel stupid i forgot that a year ago I had disconnected the ignition on one post. I realized that and reconnected them. And well guess what I now have spark haha thanks for all the help.

A resistor wire is used on a '63 F100.

Before you mess with the wiring, have you tried a jumper wire, as described 2 posts up?  That will guarantee that you have power to the ignition so if there is still no spark, it's probably not wiring.

What is the condition of your battery?  Make sure it is fully charged and then check it with no load and then check it while cranking.  If the voltage drops much below 10volts, it's getting to be time to replace it.  What could be happening is that the starter is using all of the juice and dropping the voltage enough that other things aren't working properly.

I have a 63 f100. I have never seen anything that looks like a ballast. Where exactly is it located maybe I am looking in the wrong area. I don't know if the last guy that owned this truck if he changed something or not. I have treys a new coil and I am still not getting spark so it must be in the wiring cause now I am not even getting spark when I let off the starter button.

Disconnect the wire on the + side of the coil.Then run your jumper from batt + to it.If no spark then you have a bad coil.

Ray, the ballast resistor should look something like this.

Instead of waiting for someone here to post a picture, why don't you post a picture of what you have and how its wired.  Perhaps then someone can then help you.  You may have to go back to basics.  Do you know if your ignition switch is working or wired properly.  Also remind us what vehicle you are working on.

I just went out and looked. I only have one wire from the ignition that I can tell at least. Where is this ballast you keep mentioning? Any chance I could get some pictures of the wiring and ballast to help me locate it. I also tried going From batt to the + terminal with a jumper wire and I still got no spark This is very wierd.

If you run a jumper from battery positive to the + terminal on the coil I bet you will have full time spark and the engine will run.If so famdoc has it right.The stock wiring harness has two wires to the + terminal on the coil, a wire that sends a full 12 volts to the coil on startup and another wire to the ballast resistor that cuts the voltage back when the engine starts and the key is in run position.If you dont want this go to NAPA and buy a coil that does not use an external resistor and run it on straight 12 volts.

The condenser on the coil has nothing to do with the ignition.It is a static suppressor intended to prevent static in the radio.

Ok I am a little confused. I have one red wire that I makes when I took it apart that
Goes to pos terminal on coil. Than there is the black wire from the dizzy
That I have hooked to the
Neg terminal. Than the condenser next to the coil
That I have hooked to the pos terminal. Am I missing
Something. There is a good size wire from the neg terminal on the battery cable that has a spade plug but I don't remember if that is suppose to be hooked up. Are there wires elsewhere that you are talking about?
