Low battery voltage help...
A few days ago I got the Check Gadges light bc my battery was running at 1/4.

Today on my way home my battery slowly went down to the red so I went to auto shop and yes my battery was bad and I couldn't start my Jeep. I replaced the battery and the voltage meter is still at 1/4 with the CG light on!

Any suggestions?? The guy at auto shop said it could be my alternator but the alt is only 2 years old

Probably the alternator. Have it tested.

The Voltage Regulator is in the PCM (ECM). I ran into the same issue a few months ago. I had other issues after the local auto parts store gave me an computer for an Automatic instead of a Manual. Not a cheap fix. I would make 100% certain the Alternator isn't bad.

How can I check alternator? When they did the test they said its not charging

Most parts stores will check your alternator for free.

Easiest way to check the alternator is to start the vehicle and while running disconnect the battery. if it keeps running the alternator is still good.

I will do the disconnect of the battery I hope it's not something expensive to fix
