halor everybody....
i have a question to ask...
sounds like this...

my proton iswara(12 years old) rpm reading when idle is 1000(normal temperature)...when open aircon it will slightly decrease...maybe 900??
but...when i turning on my headlamps...my idle will suddenly decrease alot...
etc: when turn on headlamps ....my rpm will drop from 1000 to 600...
and if open aircon someore....rpm reading will at 500...n it cause my car's dashboard vibrate like hell...
why it happens???

appreaciate to those giving advise...

batery ok...baru guna half year
grouding wayar sudah ada...but oledy use for 3 years
alternator??i duno....lolx...
but...sometimes the rpm stable(means the idle that i set...but 10 times..only 2 times my rpm will stable ) when turn on headlights...

so that means most probably is my alternator want kong oledy??
n what is the signal show that alternator kong??
