97 expedition alternator problems

I have a 97 expedition eddie bauer edition with the 5.4 .

The alternator went bad so i replaced the alternator with a brand new battery and it still did not charge the battery so i pulled the alternator and it was bad so i figured i just got a bad alternator and replaced it again and still the same thing, so something is automatically killing my alternator what could that be?
I have had this vehicle for 2 months and from reading on the forum i think this vehicle might have the water leakage from the window problem. The vehicle drives fine just the check engine and suspension light comes on.Check engines are just o2 sensors.
If the water leaked on the gem module like i have been reading could this cause the problem with the alternator?


NEED HELP PLEASE!!!

Thanks

Try resetting the air suspension switch located underneath dash, above where your right foot would be on the passenger side inside the car. You could either have a ride sensor that has gone bad, a leak in the air suspension due to bad shock(s)/air bag/air line. Mine was a bad pass side front air shock that was leaking air, causing the air pump to run all the time.
Is the alternator that you are purchasing a rebuilt or new and are you sure that it is rated for this vehicle? Is it a Ford dealer alternator or one from a parts store? If you have a code scanner (purchasable from an auto parts store for under $130.00 or borrow one) run the scanner to see if any short circuits present in the electrical system. This might provide a clue as to where to start looking.
