2015 f150 electrical problems
So last monday, first thing in the morning, info screen pops up "service charging system". Go down the road to work and all interior electronics go off including power steering but engine stayed running for a whole minute and came back on. No problems on the way back home. Next day, "service brake system"and " service advancetrac" comes on first thing in the morning. Radio was blinking on and off the whole ride.
Took the truck to Ford that day which was Tuesday. They tested the battery and alternator, they passed. They water tested the truck to check for water intrusion, passed. Then they looked at codes and found low and high voltage codes for all the electronics. They determined the regulator in the alternator had gone bad. They replaced the alternator today and i got back there to pick the truck up just after the mechanic and advisor had left. Truck is still displaying "service advancetrac" and "service brake system" as well as the radio turning on and off. If anyone knows what this could be, it would be of great help.

12.5V engine off, 13.5V engine on, there is nothing wrong with charging system or battery. If there is a warning, CEL, or whatever, then the condition was temporary and simply needs to be cleared.

Each and every one one? That would be odd.
