Idling drops when headlight is on

[Ningaskugon]

Newbie po ako per matagal ng browser ng site ninyo.

Hingi lang po ako ng tulong.

My idling drops by 1000rpm when I turn on the headlights. My battery is new naman po. My car is a 91 corolla 1.6.

Hindi naman po ganito yung iba kong ride dati.

Ano po kaya ang problema?

you mean it drops by 100 rpm? if so, normal yan, considering the age of your car.

Yes, 100 lang pala from 800 idle nagiging 700.

Nagiging rough kasi eh. Is there anything that can be done para maibalik sa stable?

try mo tune up, or installing grounding kits. or baka din it's a sign of your alternator going bad. kahit na brand new battery mo, baka it's not charging properly.

Replace the brush on your alternator, or might as well replace the whole alternator.
