Asking this again because I explained incorrectly on my first post. Thanks for any assistance. I have a 2004 Ford Escape and for a while the battery light on the dash has came on intermittently, but stays on the majority of the time. I haven't noticed any performance issues other than when I get on the interstate I can accelerate up to about 60 miles per hour with ease but after that it's very sluggish to increase speed. A couple of days ago it seemed to gradually lose power. It wouldn't let me accelerate past 40 miles per hour and eventually got to where I could barely go at all. I coasted down my road into my yard and tested a couple of things to find out that my windshield wipers went incredibly slow and my accessories seemed like they had low power. I checked and the battery connectors we're a little dirty so I sanded them and I put a voltmeter on the battery and it read 12.2. I then cranked it up and it got to 14.4 volts. On my previous post I listed that it got to 13.6, which is incorrect, and caused a misdiagnosis I believe. With it getting to 14.4 I'm assuming that the alternator is good. My battery light is still on but it seems to run ok now, with the exception of once where it did seem like it was a little sluggish to speed up but it was minimal. I took it to an auto parts store and they tested and said the battery and alternator were good and it had a good ground. I don't know why the light is staying on, almost constantly, and I don't really know where to start
