UPDATE::::

I removed the battery terminals. The bottom of the terminals had that White powery acidic stuff on it...The terminals were supposed to be "gold plated" but meanwhile they look RED. I guess after use it turns that color......

I cleaned the battery posts with a brush and put on some stinger battery terminals. So far no dimming..

 

yeah,i was going to suggest cleaning the battery terminals because alternators don't slowly stop working. like an ignition coil,they either work or stop working with no notice. sometimes,you'll hear the bearings lock up right before it shuts down and starts to smoke. easiest way to tell if the alternator is bad is to pull the positive battery terminal off while the car is running. if the car stalls out,then your alternator is bad.

 

my car dims when abs kicks on... but i think its just cause it puts a load on the car
:dunno:

 

I ended up buying a battery also. The one I had was the same one that came with the car when i bought it brand new.
Plus, I took it out of its location in that plastic box it sits in. I saw there was alot of gunk and stuff on it looked like acid leaked or something. so I went and bought a new one.
