My alternator is exhibiting signs of failure, meter reading shows it not fully charging the battery.

Mechanic said its just a normal wear & tear problem, he also advice to buy surplus alternator and not brand new replacement..

Tsikoteers, may I ask why surplus ang inadvice ng mechanic ??

Based on your experiences, brand new replacement ba bibilhin ko or surplus ????

Also, does a weak alternator slows the car's acceleration when the aircon is on ????
