voltage regulator. it may be in the alternator, or remote mounted. ((the alternator can be charging, but if voltage regulator is'nt working then it won't allow voltage to get back to the battery to keep it charged
Charge the battery to full. Start engine and apply voltmeter to battery posts. Reading should be 13.5-14.5 volts runing. If you read normal battery voltage then alternator is not charging. Check all fuses with test light. Power on both sides of same fuse o?k. Power on one side and not the other burnt fuse. Sometimes when looking at fuses they seem o/k. If they burn close to one end it can be difficult to see. Suggest using test light to be sure. There is a gauge fuse in the system and if it goes it stops power to the regulator on the alt. Hence "no charge" Hopr this helps
Cables from alt to battery can be deposited/burned/oxidized. In this case battery wont get charged. Also check the alternator connections. Cable might be burned or not tight enough
Also serpentine belt might be not tight enough
