Check battery to motor and battery to body ground bolts for corossion, also check motor to body ground strap for corossion. Bad ground can cause all kinds of electrical gremlins

Needs to verify the regulator into the alternator. Probably needs to be replaced.

See how many amps your cooling fan is pulling when your battery light comes on.If it is pulling more than 40 amps it is 10 amps shy from shutting down the alternator .at idle with ac on defrost lights and radio and in some cases will fry the alt rectifier.ford has written a tsb on this issue but will not let the public know about this issue.

Why would the battery light come on but be really dim? it comes on when the rpm's go up


You may have an alternator that is getting ready to go out. Have you noticed a whinning sound that increases / decreases with engine speed? A diode going out in your alternator will sometimes produce a whine and will reduce the voltage produced, eventually not keeping your battery charged.

Take car to an auto parts store for alternator check. Many stores will perform this test for free.

Good luck!

Battery light comes on and stays on...


I was just reading on another forum about the Ford Escape Battery lights staying on. They said it was the overflow reservoir being low. My 2003 Ford Escape XLS battery light has been on for 6 months. I went to autozone last Wednesday and they said my battery was bad. I got it replaced yesterday. Battery light still on.
So tonight after I read the other forum, I figured it would be worth checkng. My reservoir was about 1/2 inch below the full line. I filed it about 1/4 inch above the full line.....lo and behold, the battery light went off when I started the car. How freakin stupid. But there is your answer.

Why does the battery light keep coming on after


The battery light indicates insufficient voltage. I would recheck all the battery connections to be sure they are clean and tight. I would also have the alternator output tested, since the light will come on if the alternator is not providing sufficient voltage to keep the battery charged. Take the vehicle to an autoparts store and they will test the battery condition and alternator output for free. Sorry for your trouble and I hope this helped, Best wishes.

Why would my battery light stay on my 2002 escape


The light indicates that the battery is receiving insufficient charge voltage from the alternator. Take the car to an autoparts store and have the alternator output checked. Most parts stores will do the test for free. Sorry for your trouble and I hope this helped. Best wishes.

2004 Ford Escape Electrical problem


This is a problem with the alternator. Diode rectifiers and voltage regulator replacement will give this baby a 14.2 voltage output. In this 3L V6 SUV removal of the alternator requires removing the right tire, the right axis and undercovering to reach the 6G alternator. It is a 133mm rectifier with a motorcraft, The serpentine belt is better removed from the bottom. Also keep a bucket on hand to recover the oil from the transmission.
