Also, make sure you have voltage to the coil while cranking, not just sitting still. Why was it not running in the first place? It is possible to have a bad coil and it can ohm out correctly, I have personally seen it before and I know that I will see it again.

Sounds like you did everything right. Unless the ignition wire has a resistor in it, it should be 12 volts at the + positive side of the coil. I never checked mine with a voltmeter, but I believe this is correct.

Well in theory the coil shouldn't be bad (brand new)
it wasn't running because the red wire coming off of the Pertronix igniter in the dist. got wrapped around the rotor and ripped it out, so I had to get a new one and when that happened somehow my coil got cracked. (Was leaking the oil out.)

I don't think it has a resistor in it but I don't know...I'm not to good with electrical stuff..

the most I get on the + side of the coil is 6-7 volts. Should I test it while cranking the engine too, like suggested above or will this damage my voltmeter?

The wire to you coil should be a resistor wire...points need 12v to fire, the extra wire on the starter relay, then in normal run only need 6 to 7 volts to run. So your voltage is correct. Put some points back in and see if it will run that way. I have always had bad luck with Pertronix. If it were me I would switch to a regular ford duraspark or MSD. I just installed a Pro comp system last night, only took a couple of hours and looks very close to MSD for 1/2 the money.

Bump

now im getting 1.5 ohms on the coil, but only 6.7 volts. battery is full 12v,
i don't know of anything it could be?!?

Go through the troubleshooting section on the perronix instuctions. If that fails to get it going, take it back and get another one. They are known to be bad right out of the box. Like most electronic devices, they either work or they don't. It looks to me like you got a bad one.

Yep. If a customer wants petronix, we recommend they get two.
Did you set the gap to .030 on the pet ?

Here is how you can test the coil.

1. First unhook everything from the coil to start from ground zero.
2. hook +12V to the coil "+" terminal
3. Put high tension lead in coil and secure other end to provide a spark gap somewhere to ground
4. run wire from a good ground to coil but don't connect to coil yet
5. now touch the wire from step 4 to coil "-" terminal
6. when you remove the wire from the "-" terminal you should get a spark from the high tension lead

You forgot step 7.

pick yourself off the floor when the fuel vapor explodes because the whole engine compartment is flooded fromcontinuously cranking without spark....J/K
