You said that your alternator was mounted 'backwards' and I'm assuming that you have the Trilogy SC installed.
Perhaps there is a ground strap that wasn't reinstalled when the SC was installed ?
A poor ground can cause all kinds of problems and they don't necessarily show up immediately.
Find out how many ground straps you are supposed to have, their locations, and check all of them for tightness and resistance.
Just checking the ground terminal of the battery cable/battery connection isn't good enough here.
If all of your ground straps are in place and secured, then I would suspect that your BATTERY has a shorted cell in it.
This explains why the Alternator is constantly charging at 14.4 volts.
It is supposed to regulate itself between 12.5V and 14.4V.
