2002 XLT 4X4 w/ Battery Light on

[gnorton52]

Hello All! ... I've got a 2002 XLT that I've put a new Battery and Alternator on 4 months ago. The Battery Light has come on but there seems to be no problems. The battery stays charged up, the lights don't dim (even at an idle) and the alternator is putting out almost 14 volts at an idle as well.?????
Has anyone run across this problem??

Welcome! Your question might be moved to another area, not sure. Just curious, but what prompted you to install a new batt and alt?

Where is College Station, TX?

Welcome to this forum! Have the alternator tested anyway since it could be a problem with the regulator or a diode.

Hello Donner! Thanks for the reply, and thanks for the welcome as well! The Alternator & Battery were replaced because the previous owner had plugged in a "power inverter" and noticed that the lights would dim while using the inverter. Then the batt. light came on. So he replaced both the battery and the alternator. But the light stayed on. Replacing the batt and alternator seemed to correct the "dimming problem" and the alternator is charging 14 + volts. The Battery stays up but the light won't go off. All grounds have been checked and the alternator bench tested and shows to be good.

College Station, Texas is approx. 100 mi. east of Austin, 100 mi. North of Houston and about 250 mi. South of Dallas ... it's the home of Texas A&M University.

Thanks for your help!!

Now is the time to troubleshoot the vehicle's electrical system, since the alternator tested fine. Check Autozone's website for a schematic diagram.

Anybody ever find the problem? I have the same issue after replacing the alternator.
