If possible, check output from the alt right at the main power connection to see if it's putting out. I know what a PITA it is-I have the JRSC also. If you register decent voltage at the alternator itself, then do a continuity test on the main lead from the alt to the battery. that will tell you if there is a fusible link that is burnt. I don't know it the focus has one, but most cars do. Just be sure to disconnect the negative terminal from the battery when you do the continuity test.
it is highly unlikely that the new alt is bad, unless it was damaged upon installation. Good luck-let us know what happens.

What was the voltage of the battery when the alternator was installed? What is the actual voltage at the batery when the car is running? "failing battery" doesn't help us here.

If the battery had a low charge when the alternator was first installed, that can damage the voltage regulator built into the alternator and cause the same condition You are having.

it was at +- 11 volts and it turned over on its own power. the 2nd time i tryed to start it i had to jump it...needless to say i have gave it to ford to look at and they have told me that there is a short in the 3 wire plug, and the ecu is not reg. the voltage like it should... if this is true i dont know??? does the ecu control the voltage???
