How do I uninstall and install an alternator on a '93 thunderbird??

Ericka1 hold up on the alternator! You have a new battery in the car, now what's going on? When u turn the key on, does your engine turn over (crank)? The alternator charges the battery when the car is running, if u have a new battery in the car, it should start, even if the alternator is bad. The alternator would cause the battery to lose it's charge if it is bad. So, 1st thing to check (if car won't start), is there spark at the spark plugs, and is fuel getting to the spark plugs. You must have both for the car to start and run. Check that out 1st, and provide info, we can take it from there.
