alt charge not getting to battery

I have a 03 Taurus 3.0 v6 battery goes dead while driving,The alt is charging spoke to man at auto zone said another man had the same problem and it was a fuse in engine compartment but did'nt know location ?? Does anyone know location of fuse??

Fuse F1.26 (10-amp) in the Battery Junction Box goes to the voltage regulator of the alternator. There is also a 175-amp maxi fuse between the alternator and the battery.
