Does the alternator work? Does the light go out if you unplug the plug in on the alternator?

    It should be plugged in to the side of the alternator. Just because it's new doesn't mean you got one that isn't bad.

My altanator light came on today what could it be

the alternator or "battery" light will typically come on when charging voltage is too low. Check for voltage at the batter with the vehicle running. If you see less than 13 volts than the alternator is likely not working anymore.

If this is a v-6 model the alternator can be a little tricky to replace. The passenger side tire, splash shield, and drive axle will need to be removed before the alternator can be removed.

I’m happy to assist further over the phone at

Battery light is on n ijust put a new battery

Could be your alternator. Typically the battery light goes on only where there is a failure in the charging system. The batter has no built in feature to trigger a light fault. Go by any sears, autozone, parts supplier and they can test your charging system. It does not cost anything and give you an answer in 2 minutes. Also, if your car is putting out less than 13 volts while running you have a charging issue. That will drain the battery.

My battery light won't go off even though i've had the alternator tested and installed brand new battery

well; on your car, the alternator has an internal regulator. have you checked any wires or harnesses that ran off the battery? And see if you may have a cut place on your cables, or if one has come loose from the ground.

2003 ford explorer battery light on

Are you sure the alternator isnt "over" charging? if not, you may have a "loose" connection somewhere with the cables, or a malfunction in the dash cluster. Also, are you positive the battery is forsure good?
