Head Lights got dim a bit when ever A/C turned ON

[arif_siddiqi]

Hi,

Is this normal that car Headlights got dim and back to normal when A/C turned ON. In night when ever A/C is ON, the Head Lights got dim and back again as if the current to Head Lights got less. This happens every time when A/C turn itself ON manually or automatically.

I hope I have cleared my self.

Regards
Arif

It shouldn't happen if the alternator/generator is producing enough power.
You may check it by using a multimeter. With car started, AC, headlights, audio system and defogger on, read voltage should not go below 13V. Without any load, voltage should be 14+

Experts may be able to guide better.

is the car mehran?

if yes then its a comon issue of alternator not putting the desired current on full load.
u can check at the battery guy.

if not mehran, get ur car alternator charging check and battery also.
