Question CJ5 Starter Issue

I have a 1978 CJ5, the starter solenoid failed and I replaced it with a new one. The issues is that the solenoid will not work. If I apply 12V from the battery it engages. I measured the voltage that is coming to the solenoid and it reads 12v. It's not a ground issue on the solenoid. Could there be a voltage drop somewhere in the ignition circuit?

Thanks Fuzz401...
I do have 12v at the blue wire, but it will not activate the solenoid. If I connect a wire to the '+' terminal of the battery to the selenoid it will activate.
Thats my issue, the blue wire from the ignition (which shows 12V when I put the key switch in start position) will not activate the solenoid. If the blue wire delivers the 12V could there be some loss that makes it to weak at the solenoid?

Very puzzling to me?
