Battery Light On

[Dman]

I have a 2013 Expedition XLT.
Battery light comes on intermittently, stays on a while then goes off, comes back on.
Changed battery due to its about 4 years old. Still same issue.
Dash voltage meters indicate charging and full charge on the battery. does not go lower.
Could this be a fuse issue.

Could be many things Possible battery issue or wiring connections or Alternator issues.
Get a Volt meter and read the battery voltage with everything off. Then start engine and run it at 1500-2000 rpm's and read the voltage at the battery.
With engine off you should have about 12.6 volts with engine running at those Rpm's you should have about 14 Volts

Has the Alt. ever been replaced?

If it's a nuisance battery light on, please check Ford TSB 04-14-9 for details on the fix. Basically it is a change of the wire harness from the alternator to the battery and other associated elements, and a reprogram of the PCM to the latest calibration.

Check tsb cause that's too soon for either a failed battery or alternator and any thing related to those two.
