Pickup my car this morning good news is that the battery is holding its charge. Replacing the AC/deftrost control module appears to have fix the issue for now. Charging is at 14.7v even with all loads present. The not so good news is that Ford working with the local dealer was still insisting that it was a charging system issue unrelated to any of the other system and was on the verge of sending out another alternator. Fortunately for me the technicians at the dealership (Carpino Ford in Columbus, KS) got fed-up with the response from Ford and began to look for everything or anything beyond just the charging system. I don't know if Ford doesn't have confidence in the technical abilities of their dealerships or if they are just to busy to spend the time to look at issues like this. I don't know if the other folks on this forum had or still have the exact same issue but if so give this information to your technican and see if it helps.

We may have my issue fixed. The local dealer has identified the module that controls the defrost/air-conditioning system as having a short to ground. The short is active while the car is running as well as when it is turned off. They found the rear defroster is still active even when the care is off. A new module has been ordered but won’t be here until Monday. Good news is that with the module unplugged the battery maintains its charge. Keeping my fingers crossed that this is the problem

Still no answers from Ford. Seems they have bigger fish to fry. As for PCM I suggested that it might need to be looked at again to the Dealer.

Thanks for the suggestion but I think I will stay with the local dealer for a while longer. These guys are going out of their way to help figure this out especially since this is not a warranty project. BCM checked, diags ran and showed nothing out of the ordinary. Dealer pulled several of the differnet system fuses and no changes noted. I am told that some of the system fuses can not be pulled as this could cause damage to other systems. As of this afternoon alternator 4 change made no difference and the Ford folks are rethinking their approach. Guess there is always hope for tomorrow!

No shifting issues, no error codes, battery drain is significant if headlights are being used even when being driven. Charging voltage drops to 11.4 volts and lower at idel speeds. With no load (lights off just maintaining normal operations on radio, nav or other option being used) voltage starts at 13.5 after full battery charge but then drops below 12 volts within 10 minutes even with car running at idel. As a check with battery disconnected it maintains its charge so the drain is from the car. I am very frustrated that there appears to be no logical way to isolate the source of the power drain. I have put a volt meter on the battery while it is running setting in the dealers shop and you can watch the voltage drop rather rapidly, a few tenths of a volt every few seconds.

Battery was tested connections check and tested everything the Dealer and Ford can think of including the software upgrads and diags. Ford still contends that its and alternator issue. Even with the the alternator disconnected the drain is still there. All voltages check with what ford says they should be but still it will not hold a charge.

Have been looking through this forum as my 2013 Edge (78K miles) also has a dead battery issue. It started about two weeks ago on a weekend. I took battery to Auto Zone and they suggested the battery was less than good so I replaced the battery. Lasted 3 days and car was dead again. Called local Ford dealer and took it in. They diagnosed alternator issues so one was ordered and installed. Had to go on a short trip about 150 miles and when we shut off the car and tried to restart it was dead. Had a set of jumper cables (as a backup) so got it jumped and took off for home. Drove about half way had to take a break and turned off the car and it again was dead when we tried to restart it. Again got a jump from a kind young man and took it home. Called the Ford service dealer and as of today Ford has instructed them to keep putting in alternators until the problem is fixed. Ford claims they have had a bad batch of alternators. I doubt this is the issue but I can only hope. You can put a meter on the battery and watch the voltage drain down slowly. All diags indicate the alternator but none of the replacement (last I heard was three) replacement alternators act any different. The dealer is in touch with Ford but they say Ford hasn't seen this issue and this forum clearly refutes that claim. Since I am past the warranty millage I don't have the leverage on Ford that others may have. But I have had 18 new Fords since 1967 and this is the first with any issue like this. I am going to let Ford have their stab at the issue but not much longer. Has anyone had any sucess other than vehicle replacement?
