Need help troubleshooting

I have a 2004 Wrangler SE while driving yesterday, the check engine light came on. I looked at the instrument panel and didnt seem to see much change and thought that perhaps the batt setting was a little low (10-12- left of the middle). Today, the engine light came on and half way through my commute, I noticed that I lost the reading on my radio (clock), the mileage reading was very light and when I went to use the signals, they worked at first, but then stopped. The batt reading was very low and to the left.

Now historically just as a side note, the engine check light will come on when the oil pressure gauge fluxuates and it will do this from time to time but is not currently the problem.

Where should I start to look? Is this possibly fuse or computer related?

Thanks!

See what codes it's showing.I'd get the battery and alternator checked for free at Advance auto or Autozone.

Code says p1682. Is that difficult to replace?

That code is fairly common & is often from a bad alternator.

Does that end up being an expensive repair?

Rebuilt alternators aren't expensive. But before you buy a new alternator, have it tested. Personally, since I get so far out in the boondocks, I would go for a new OE Mopar alternator. I don't tend to trust rebuilt or aftermarket alternators, especially if they come from a store like Autozone.
