Is there a fuse for the charging system?
Although all cars don’t have an alternator fuse in them, the vast majority of them do. Alternator fuses are put into place to allow an alternator to operate. They’re small fuses found in the fuse boxes of cars that control alternators and help to keep them up and running.

There are 2 fuses for the alternator. One is usually a fusable link (wire) for connecting the stator diodes to the battery, and a lower value fuse (10 to 30 amp) for protecting the field (rotor).
What stops alternator from charging?
If one wire is disconnected or is damaged, then the power will stop being generated and running to the alternator. As a result, the alternator can’t charge the battery. The only solution is to figure out which wire is damaged and replace or repair the wire.
Why is my charging system not working?
Another common problem that can cause the charging system to fail is a broken alternator belt or one that is worn so bad it slips badly. If the alternator works properly but the belt doesn’t spin it fast enough, the voltage output can drop and cause the system to act as though the alternator doesn’t work.
