I think your correct Jack
Its actually a Alternator Pinpoint Test
Iv used it worked Awesome even better then Oreilys bench test
he needs to specify or I missed it does he have Dual Alternators??

Thank you for everyone's eyes and ears.
I get it, chilton/hayes sucks, but it's what I have in hand at the moment.
Single alternator, dual battery (third line on OP).
Just to be clear, what is the exact procedure to test the LG/RD wire? voltmeter, black to passenger neg post, red on LG/RD clip? trying not to fry everything with a bad jump.
I'll check that fuse when I get home.
thanks,
mike

From the '03 design level this is the Ford Manual test methodology. For the possible '06 curve ball you've thrown, can't help.
A voltmeter is all you should need. The sense wire should be battery voltage all the time. The control wire should only have power with the key on.

Thanks Jack-
I appreciate your time.
Are those manuals available to general population?
Based on what I've read, was hoping you would have the answer, now i'm more concerned.
thanks again,
Mike

I'm not comfortable stating one way or the other since I don't have the '06 layout in front of me. But reading volts isn't going to screw anything up.
You'll find official and copied Ford service manuals on DVD from eBay. I have three. There is also an online subscription that can be had that I used to use at work and you'll also come across people who post open links to those.
Often Sean posts sections that people are looking for here he has if he reads the thread.

Update
Fuse #45 10 amp is good
Resting battery volt 12.2
results from Alternator switch point test (?):
LG/R: KoffEoff = 0 KonEoff = 0
O/LB: KoffEoff = 12.2 KonEoff = 11.3
Additional observations:
When turning key to accessories, the Low Voltage idiot light does NOT light up.
Thoughts?

Mike,
I would recommend touching base with Circuit Board Medics here on the site. Around '06 Ford started to control different functions through the dash cluster, something I have not bothered to understand. They may be able to confirm if the cluster has a history of faulting and not turning on the alternator.

check for continuity
Is it possible to check for continuity between the plug on back of the dash through to the alternator connection?
I also read somewhere about jumping a circuit to force the low voltage idiot light on for testing purposes. Can anybody point me in the right direction for that?

Check for power at the fuse key on one of the two blades the fuse goes in should be hot
Ohm the fuse itself
That alt wire just needs key power you could hot wire it
but I'd dig into it more first
