Pertronix Igniter or coil
On my 65 V8 I am only getting 7v when everything is hooked up correctly (coil wire and brown wire to solonioid . If I disconnect the power to the coil and test that I get 12.5v. If I take off the power to the coil and test the brown wire from the solonoid I get 12.5v. Could it be a bad coil or Ignitor. I am getting power lost from one of them.

If you got 7v sound like your pulling load..

Like 2+2GT said, 7V is about normal. The factory resistor wire is supposed to drop voltage to coil to keep from burning up the points. The Ignitor I will run fine on 7V, but the Ignitor II may or may not work properly without a 12V feed.

+1 on the ignitor 2 requiring 12v. Which version are you running? 2 and later require a full 12v as stated in their instructions. 7v to the coil if you are still running the pink wire from your ignition switch to the firewall is perfectly normal. The pink wire is thicker and acts as a resistor wire reducing the voltage.

I don't think I understand what you're talking about. The brown wire to the solenoid should be 12v. The coil wire you're talking about should be red/green, and it should only be about 7v to the coil. Try to explain again exactly what wires you're testing, how you're testing them, and whether the car is running or not, etc. The more information the better.

Voltage only drops under a load. No matter how much resistance you put in the circuit, you're going to get 12V before anything is hooked up. You'll even get 12V sometimes with things hooked up, as long as the primary circuit is open. When it's closed (while charging the coil) is when the voltage drops down to ~8V.

The brown and red/green wire r both 12 volt when not hooked up to the coil. When it is hooked up it drops to 7.5 volts. What makes the voltage drop. That is if its suppose to. I am testing this with a volt meter not running.
