Is there a fuse for your alternator on 2001 BMW 740i?

There is no single fuse that protects the alternator in a 2001 BMW 740i. Instead, the alternator is protected by several fuses located in the car's fuse boxes. These fuses include:

* Fuse F38 (7.5 amps) in the under-hood fuse box

* Fuse F54 (5 amps) in the under-hood fuse box

* Fuse F129 (80 amps) in the trunk fuse box

If any of these fuses blow, it will prevent the alternator from charging the car's battery. This can cause the car to stall or experience other electrical problems. If you suspect that the alternator fuse has blown, you should check the fuses and replace any that are blown.
