Battery Gauge Drop. Check Gauges.

Hey all, so tonight i got in my jeep as usual and something different happened as i was driving. the check gauges light came on and my battery gauge dropped all the way down and my headlights got real dim. nothing has happened like this ever and nothing seems to be broken to make this happen to my knowledge. my battery is only a year old. what could be causing this problem? any help is greatly appreciated.

Thanks

I would have the alternator tested. That sounds like the culprit.

Typical of an alternator going bad; and it will throw a code. You can run a quick test the atlernator with a digital voltmeter. Should be around 13.5-14V or so at the battery while eng running. There is a voltage differential between engine off and engine on (when atlernator is charging), if not, the alt is not charging.

There should be like a stud behind the alternator, try to move it see if power comes back. This worked temporarily for me to keep the battery somehow charged til I got around to fix it... Don't wait too long cause you'll drain the battery and shortens its life quickly, not to mention you'll get stuck somewhere.

My Alt recently died and not realizing it drove it, (just around the block) I was running on just the battery and killed that too.

My alternator never threw a code but did have a similiar set of problems before it died.
