This is remedial performance tech. There is no fuse between the alternator and battery or alternator and PCM. Did you arch the new alternator or your old one? Old = ohm (measure the condituity) the alternator output wire at the battery positive wire end. It should be a good low ohm circuit, if not it's burned open. New alternator arched = take it back and try again with the battery disconnected. If none of this makes sence to you then take it to a mechanic.

use a multi meter set on volts. hold neg. lead on pos post on battery and other on the back of alt. it should read 0 or very close to it. if it reads battery voltage than then there is open or high resistence in that wire. u also need to check the L-terminal on the alt. for voltage. if none of this makes sense just start the car and put a screw driver on back of the alt and see if there a magnatic field there. if so the alt is charging.
