Need Help Diagnosing Bad Alternator

[Dino]

Since we start talking about alternator here what in my VX going on. When at night with lights on and everything im using my horn all my dash going dimmer same if im rolling my windows up everything going dimmer and my headlights. Could that be alternator?
P.s battery is new.
thanks

YES! This is a classic case of not enough current to keep up with the demand from accessories like head lights, stereo etc.

Always check battery cables FIRST! This is the weak link in the system and is at fault many times. If this is OK, then an alternator is needed for your VX djkymar.

Have you checked ALL of the cable connections? Remove the battery cables and check for corrosion and then retighten securely. Check the body grounds and the alternator cables. Most auto parts can roll a tester out to your vehicle and test both battery and alternator. Does not sound like an alternator problem based upon what you have posted.

Please post the results when resolved.

yes i did check all my cables adn connections and everything good. The story with is going on for awhile when i had my old battery it happend only when i used my horns at night then my battery died i got new one adn everything was still the sane (dimming at night only) but a couple weeks ago i nocided it dimms when i roll my windows up and even at day time i can see light on my dash dimming a lit bit without headligths on. So i start suspecting my alternator and im probly going to get the one that biju reccomended.
