Alternator wiring - where did i go wrong!?

ok I need the alternator working by tomorrow or i will be sad face!

I have the dodge cummins alternator, and my ford regulator.
The ford regulators are popular to swap onto cummins trucks as well.

I wired it up but when i put the tester on the solenoid it only reads 12 volts...

I wired it like this
http://www.cumminsforum.com/forum/94-98 ... -02-a.html

So the alternator has one big stud on the back and two small studs.
I connected the big stud to the A blade on the regulator with a huge gauge wire.
I connected one of the little studs (Read it doesn't matter which one you use) to the F blade.
I connected the other little stud directly to the alternator for a ground. It's just 1" of wire going from stud to alternator ground.
I connected the S blade on the regulator to the fat wire that runs down the inner fender that goes to the ignition switch because in that link it says to run the S blade to the ignition hot wire. I guess that would be this big wire..
But then obviously the ignition needs power! So I hooked these wires (S blade and big ignition switch wire) up to the positive cable peg on the solenoid. So now the truck starts and has full power but I'm not getting anything over 12.2 volts.

Where did i go wrong

Or do it easier and install a Dodge regulator. 3 wires: 1 charge to batt, 1 keyed power, 1alt field. Case of regulator gets grounded, other field terminal on alt gets grounded, alternator case gets grounded.

For what you have it almost sounds like you're running charging curremnt through the regulator? And you may also have the regulator hooked to a wire that is always hot?
