need help asap, power loss lights dim evil noise
 

Alright so tonight i was driving around with some buddys and we all started noticing little flickers in my headlight and instrument panels; within seconds we would hear a noise that sounds like a bad pully or the starter attempting to start. What is the cause of this is it a bad battery connection? Terminals or maybe it could be that i dont have a housing on my battery and its free floating and moving around to much? i cant have an issue like this just, the jeeps only a month old to me and its my only car at the moment. Deffinently need some help on this one!

check under the hood for some thing rubbing and noises

If you can get it to autozone, or Advance auto they can test your charging system for free.

Pulley sound may be the alternator. Easy to replace, with a rebuilt unit.

battery loose fell into fan or pullys ?
