you may have missed a fuse or fusible link , there is a 100amp alternator fuse and a 50 amp fuse on that circuit , location of those 2 fuses are (left side of engine compartment) also there is a fusible link in that circuit right off the positive side of the battery , those big fuses don't look anything like a normal if that helps , cheers'

Generally if charge light is on, alternator has a bad diode in it. This lets the charged battery lose its power by flowing in the reverse direction. It sounds as the alt., is either not connected right or is swtill bad

take a volt meter and have it set to the dc mode
probe the meter red on positive and black on negative to the battery with the engine running.
you should get a reading of 13.5 volts.
if not the altenator is bad
next you can do this test which is easy to do.
sway the two probes around, red on black and black to red
if a reading shows up the diode in the altenator is bad as well
the diode is to keep the currebt going one way to charge the battery
if flow in reverse no charge will be made to the battery
