Did you have a battery tender attached the whole winter?Out of the blue, after a winter slumber…..MY TURN! lol. Brand new Die hard gold battery, pigtail SEEMS fine….and battery now at 11.3v Hoping it’s just the alternator. Wish me luck!
. Wiggle tested the three wire connector; nothing. Haven’t checked fuses 24 and 36 yet, (left the car elsewhere) but i pln to check those, and ordered the WPT-118 connector, figured i’d start there before just going right for an alternator. Main reason being, this error popped up for me TWICE randomly, then vanished while going through a car wash. (Which i have ceased doing) It is leading my brain towards a short in the connector or subsequent wiring, perhaps it finally took out a fuse as well. I’m soon to be doing a boatload of work to the car, which includes a barton shifter, jacking rails, subframe brace, replacing all fluids, and the PP3 install along with the upgraded VCT’s, so i figure while i’m in there, it will be a good time to check/replace the harness, and do new belts/replace the alt if needed. Been stockpiling parts all winter, going to take a week off to get it all put together 
I had the same problem recently and replaced the alternator and all is fine now. I replaced the pigtail connector as well just for the hell of it.Out of the blue, after a winter slumber…..MY TURN! lol.

I’m thinking of taking the same path. Did you just go with a Motorcraft alt? I don’t need anything really upgraded in that area, but am not going cheap either. Probably going to grab the M/T 200A unit
Yeah I didn't get anything fancy. I believe I actually got a refurb. unit
