I can't. When the ignition is turned "on", the SCT tuner loses power. As if the OBD port is not receiving power as well...
I've just seen alternators do crazy things. There are a lot of things that can go wrong with them. Twice, I've had the diode fail and drain the entire battery (killing it in the process) overnight. I've also seen the alternator play hell with the electrical system, set CELs, etc... It's so easy to take the alternator out and run it to the parts store. I would rule it out before really jumping into the wiring.@flapjack, what makes you think of the alternator?
Have you looked at your BEC yet? Where did you relocate it to? There are 3-4 screws that hold down the main plugs to the fuse block area. If that comes loose (even a little), you can have all sorts of problems. I would check to make sure all of those screws are tight and the housing is not hung in any of the corners.Checked #19 fuse yesterday, still good. Need to see if I can get ford to check my SJB, or if there is another S197 in the area where I can swap theirs to see if that is actually the problem. Any takers?
Yeah. I'm starting to get the feeling the PCM took a shit. Hopefully tomorrow morning I can check over the wiring and other fuses and what not.

Oh and I've had the SJB out of the car twice to dry it off. It didn't rain hardly at all the night before, though I will pull the SJB and check it out.
He is correct. The last steps of each pin point test will be to check the pins of the PCM plugs for loose seating, bent pins, corrosion, etc. I know PCMs can go bad.... I've just never personally seen it. I wasted money on a PCM while troubleshooting a TB related issue a few months back. You may want to search for my thread. It might save you some time troubleshooting.The PCM comes up last on the diagnostic checklists that I have seen. There should be a full diagnostic checklist out there for the electronic throttle control system. Unfortunately, I didn't find a full list in the quick google search that I just did. But if I have time later today, I'll try again.
The full list should include tests of the voltages & resistances in the circuits to the tps, actuator/motor, & accelerator.
Here is a link that describes general throttle-by-wire systems: http://www.aa1car.com/library/throttle-by-wire.htm
Is the the ticking coming from the throttle body motor?
