    normal ba sa alternator ang reading nya pag natakbo is 12.9 to 13v pag may a/c? minsan pag cold starting 15v to 14.5 reading pag mainit na 13.5v pag on ng a/c 12.9 to 13v. as of now wala naman akong nakikitang problema pero gusto ko lang maka sure na no worries at all

    normal po ang charging system nyo

    normal medyo bumaba voltage kapag ginamit ang a/c & headlights kasi heavy loads sila

    normal din medyo mataas voltage kapag newly started ang engine kasi mataas charging current supplied by alternator to recover from recent high dischage from starting ... usually less than a minute, balik na sa normal reading around 13.8 V on idle without heavy load
