Best Answer

No. The short summary is that there usually is a fuse or circuit breaker in the line coming out of the alternator that protects the alternator from a sudden surge in power from some outside source and which also protects the engine's electrical parts from a sudden surge that might somehow come from the alternator (very doubtful this would happen). But that fuse doesn't keep the alternator charging in the strict sense of the phrase. What stops an alternator from charging is internal parts failure such as the burn out of a rectifier, bearing failure or the belt which drives the alternator failing or coming loose and slipping excessively. Short of failures such as these an alternator will keep on charging as long as the belt is turning its pulley and causing the rotor inside the alternator to turn.

Is there a fuse on an alternator?

no there is not a fuse built into any alternator that i have seen to date (been a mechanic for 10 yrs) HOWEVER most vehicles have a charging fuse located either in-line or at the fuse panel so that if the rectifier or voltage regulator goes out the battery does not receive too much voltage or the wrong type of voltage ac versus dc in short no the alternator doesn't but the vehicle should have one in the alternator circuit
