WWWPerfA_ZN0W Posted April 9, 2016 Report Share Posted April 9, 2016 Any other electrical issues with the Edge? Sometimes, if the Battery Monitoring System is not reset when a new battery is installed, the charging does not occur properly because the computer thinks it is still dealing with the old battery. Best/easiest way is to have the dealer reset the BMS. Sometimes Motorcraft batteries give up the ghost early, it happens even in their Tough Max offerings. Try having it loadtested with a digital load tester. Another possibility is that the alternator is not charging properly, and if you track the voltages while the Edge is running, it should be between 14 and 14.5V consistently, preferably towards 14.5V than not. With engine & every accessory off, voltage should be about 12.6V or so. Quote Link to comment Share on other sites More sharing options...

omar302 Posted April 9, 2016 Report Share Posted April 9, 2016 Like what "WWWPerfA_ZN0W" stated, may be the Battery Monitoring System requires resetting. There is an another to reset it yourself: From this post: Carry out the Battery Monitoring System (BMS) Reset using the scan tool after the battery is connected. If the BMS Reset is not carried out, it takes approximately 8 hours for the Body Control Module (BCM) to learn the new battery state of charge. During this 8 hour period, the vehicle must be undisturbed, with no doors opened or keyless entry button presses. If the vehicle is used before the BCM is allowed to learn the new battery state of charge, engine off load shedding can still occur and a message may be displayed." 1 Quote Link to comment Share on other sites More sharing options...

Edgeyfinnerty06 Posted April 13, 2016 Author Report Share Posted April 13, 2016 Ok just had my edge at ford dealer and they said it was dead battery and my capless fuel filler was not letting pressure escape or something so they replaced battery and fuel filler 1 Quote Link to comment Share on other sites More sharing options...
macbwt Posted April 15, 2016 Report Share Posted April 15, 2016 I had a battery that was dying and had no battery light and everything was seemingly OK, but a close scrutiny of the charging system revealed that the alternator was putting out just enough charge to say it was working and if you do not REALLY REALLY investigate it and test it hard you will not find the problem turned out the voltage regulator could charge under idle but when a load was placed on it it charged but not enough to keep up with all the accessories running. This video shows the issue.

Edgeyfinnerty06 Posted April 15, 2016 Author Report Share Posted April 15, 2016 They tested my battery and said that it was only Reading 14.0 volts and failed both test and he checked voltage out of the altenator and the altenator checked out I ran my accessories and even a vacuum for 30 min off my battery yesterday and fired right up I was so happy 2 Quote Link to comment Share on other sites More sharing options...
