Mga masters pa help nman po... knina po kasi yung nissan exalta ko may squealing sound, amoy sunog at may usok pag naka on yung AC. Tapos pinagpahinga ko... start ulit ng engine and on ng AC napansin ko umilaw ung battery light. Ano po kaya problema? thanks in advance po.

Something sa alternator. Might be belt snapped or the burnt smell means fried alternator. Check if the belt has snapped, if it's not, start the engine. Pag umilaw pa ulit battery light, alternator has gone bad.

Only when the a/c is on? Try checking the a/c compressor and the alternator belts and bearings first.

i am confused... so what was wrong in the first place? why did the pulley fail only when the compressor was on?

nag stucked un crankshaft pulley ganyan din nangyari sa old b14 ko, kala namin compressor problema, pinahirapan ng pulley pagikot ng compressor kaya umuusok, we replaced the pulley ng solid metal na wala na rubber, di naman ganun kalaki difference sa may rubber pero pangmatagalan na un, buti nakita nila agad un source ng problema
