Battery light = bad alternator usually, or broken serpentine causing the altenator not to charge

I would get the battery checked, just because it's new doesn't mean it can be defective, thats why they waranty them. Could be a bad/loose plate.

If anything, take it into a battery shop, and have the full circuit tested together.

I used 3 different batteries...I swapped all my batteries from by other cars..

Where Exactly is this fuse? And would this cause a Low charge issue?

 

[ranger7ltr]

This is the MEGA Fuse in th4 underhood fuse panel...

If this fuse blows, the battery voltage to the alternator is not present...So no matter how good the alternator or battery are, the alternator gets no voltage and cannot generate power...

Ah, not the same problem I'm having.

Ah, not the same problem I'm having.

Have you tried a new belt like others are recommending?

That's my next step, I'm currently broke though so hopefully nothing bad happens until I can get my first check. (just got a new job)
