Should be in your owners manual. On most models there is a large fuse on the front of the fuse box or inside for that circuit. The maxi fuse is usually 75 or 100 amp.

When the alternator went out, it may have also smoked your fusible link that the output wire is on. There are 2 or 3 fusible links on the starter relay on the passenger side fender. This is where they catch battery power from the positive cable there, or in the case of the alternator fusible link, this is where the output wire connects to battery for recharging it. The gray colored link I believe is the one on the output wire from the alternator. When a fuse link blows, the insulation on the wire may bubble or get rough spots. You cut the old one out and splice in a new fuse link. Make a soldered joint for best practice. Or just replace the whole wire and fuse link, from alternator to starter relay, from a donor car, a salvage hunt.
May have blown some fuses under the hood. Check for an alternator maxi fuse, also a fuse that sends power to the fuse panel, or that might be another fusible link for the panel. You may need the alternator tested, might have ruined that, also.
REPLACE BATTERY CABLES IF OLD AS VECHICLE.CHECK FOR BROKEN BATTERY FEED WIRE OR VOLTAGE REGULATOR WIRES TO ALTERNATOR.CHECK FUSE LINK FROM STARTER TO ALTERNATOR SEE IF ALTERNATOR BATTERY FEED WIRE HAS POWER IF NOT FUSE LINK BLOWN..AND CHECK ALTERNATOR FUSE.
Usually it is not a fuse link, but use a test light and check that you have current at the main terminal on the alternator. If you do the fuse links are fine, so next check your belt tension this is something that is overlooked often and is the cause of flickering alternator lights. Also check and make sure your cable ends are clean and tight. If all is fine that alternator or the voltage regulator in the alternator is going bad.
FUSES ON THE DRIVER SIDE UNDER INSTRUMENT PANEL.CHECK FUSE LINKS YOU HAVE IN LINE FUSE LINK ON THE POSITIVE BATTERY CABLE. ALSO POSITIVE BATTERY TERMINAL.
check fuse and fuse links.you alternator is not receiving power .you have a open fuse or fuse link.alternator need battery power in order to charge battery.
