2007 ford escape replaced alternator and battery. Battery lite keeps coming on keeps draining battery in 1 day. what could be causing this?

If you bought a rebuilt alternator, it could be a bad one. Maybe a bad battery too, but doubtful. Rebuilt parts are cheaper but sometimes you get a dud! Otherwise you have something that is staying on and taking lot's of battery power! Take it to where you bought these things and let them take a Volt and Amp meter and test the system ! They can tell with these if your Alt. is putting out enough power to charge the battery and also see if the battery is holding the proper Amperage. It should show at least 13.5 volts in the battery after running ! Take it back !

Thank you for your input. I bought the (second) alternator and battery new. The alternator checked out fine. I was hooking it up to a battery charger every night before I could afford another new battery...so now new battery and alternator and on the third day I am back to same problem. Battery light comes on then after I get home and turn off car if I try to start up again its a no go. I have jump started it .....gotten stuck at grocery store twice. So far I have about 2 times I can start car between charging....one to get to work one to get home.

Hollysboys, something must be draining your battery from what you describe.
Had similar problem, and solved it by merely switching my cars interior lights to OFF. Seems the "auto turn off" function which is supossed to shut it down a few minutes after closing doors, malfunctioned and doing this solved the problem.
Haven't bothered fixing that, since not that important to me, so check and see if it could be something as simple in your case also.:0).

Your alternator is probably shot. Take it to 1 of the auto part stores they'll check it for free

alternator checked out fine :( Before I had the alternator and battery changed also had the plugs changed. I have spent over $3000 in the past year for issues and I am tapped out at this point. Cannot afford a new or used car at this point. I suspect there is some other reason the battery is draining down. Any thoughts on this issue would be appreciated.

Wow you've had the 2nd alternator checked already, I only mentioned it because I've had more than 1 lemon. Now you've got the wiring harness, coil, fuse block, distributor cap and rotor. Did you buy this new? If not, do you have the CARFAX or something similar? Do you live in a state that does emissions testing? I'm asking this because to check your emissions they just hook up to the computer in your car and it tells their computer everything that's going on with your car. They'll charge you $10 to $15 bucks where a garage will hit you up for $100 to $150. This way you'll have a print out of everything in your car, they interface with your car and it takes about a minute.

I bought the escape new yes. The second alternator new as well. Thank you for your input. I will look into having it checked by the computer interface.
I have had several lemons as far as rebuilt parts go...Been dealing with this problem for about a year now. I was really hoping that by having a new alternator and battery problem would be solved. Thanks again :)

You certainly have patience. Did you have the dealership work on it? If so I can't imagine them A. charging you & B. not correcting the problem. You've got a short and they've sold you a lemon, I'd make sure that any and everyone possible would know

if it is neither the battery nor alternator, there may be a direct short somewhere.

How do I find out where the short is?
Report as
I had this same problem with my mustang, I had to have it placed on a diagnostic machine to locate the short. make sure you ask them to shake the car periodically so that if two wires are touching they'll engage and show the short.

Thank you! I will ask them to shake it, excellent idea! I am learning a lot. I will be doing this on my next day off.

it took me 6 batteries (thank goodness for warranties) and an alternator ... I did the diagnostic machine thing and they couldn't find the short, if the mechanic hadn't shocked himself when he moved the wires I'd still be fighting with them.
