John AM Posted July 16, 2022 Share Posted July 16, 2022 I'm hoping that someone on here has experienced a recent issue I've run into with my 2017 Ford Fusion SE 2.5L. A few weeks ago, my battery was dead in my car. Upon inspection, the negative terminal was corroded and the battery was the original one when I purchased the vehicle 5 years ago. I bought a new battery, installed it, and the car started right up. I then didn't drive my car for a couple of days and when I went to start it on the 3rd day, it was dead. I had the alternator checked and it was good. The battery was then checked and I was told it had a bad cell, so they warrantied the battery. I got the new battery and my car ran for a few days. Again, I didn't drive it for a couple of days and on the 2nd or 3rd day, it wouldn't start. I had the battery checked and they said the battery was good, just needed charged and was on it's last 25% of life. They warrantied this battery too. I now have a new battery and I checked the Amps on it with a meter and received a reading of 1.86A. This was while the car was off and doors were closed. I disconnected the alternator and checked the Amps again, still receiving a reading on it. I removed each fuse under the hood and the number never moved. What can the issue be? Where else can I look? I haven't checked the fuses under the dash yet, because they're not necessarily easy to get to. Any guidance would be appreciated. 0 Quote Link to comment Share on other sites More sharing options...
DavidK Posted September 18, 2022 Share Posted September 18, 2022 (edited) I don’t know why you have no replies yet. I have just joined stumbling across your question in a Google search. I too have a parasitic draw I have been chasing, I hope to have finally found it. I will find out next weekend for sure. Under your dash on drivers side, after you remove the panel under the steering wheel, you will see a fuse panel. Just from my cars issues, try the #5 fuse if you have one under there.

FusionS Posted March 7 Share Posted March 7 My issue, diagnosed by local Ford dealer, parasitic draw caused by the PCM pulling .65 milliamps. Troubleshot by removing fuses and when PCM fuse removed the meter moved. Dealer replaced the PCM and meter tested again with a .02 milliamps measurement which is within the allowable range. Hope this helps! Cheaper to purchase the PCM through an online ford dealer but the dealer has to reprogram it anyway. Try pulling fuses 7-12 in from the engine fuse box. Good luck! 2017 Ford Fusion S 2.5L 0 Quote Link to comment Share on other sites More sharing options...
