how many volts ba dapat ang reading sa alternator.

pinacheck ko minsan battery ko. when attached to the meter reader ba yon eto reading

aircon on, radio on 13.5+
aircon on, radio on and headlights on 12.6+ na lang


also tested the battery using a digital tester (yung pang electronics ) and almost got the same reading.

sabi nong mechanic mahina na alternator ko.

totoo ba to or its just the battery?

kng battery ang problem, pde pa ba ito i recharge?

thnx in advance
