If the alternator is overworked — for example, when many high-power accessories lights, stereo, extra fans, air-conditioning are used — the alternator works harder than design capacity and heats up.

Internal mechanical wear — bad bearings o r friction in rotor/stator assembly — can cause overheating due to friction and inefficient operation.

Poor ventilation, dust, o r contamination common in dusty o r hot climates — dust/dirt/buildup may hinder cooling of alternator inner parts and accelerate failure.

If belt tension o r alignment is bad belt slipping o r too tight, this can cause extra load, friction and heat generation — belt issues thus contribute to overheating o r belt-burn smell.

Watch out for: burning smells rubber o r electrical, squealing from belt, grinding noises from engine bay — these can signal overheating o r mechanical fault in alternator.
