thanks trailrider.
so the fix is to r&r the alternator? or can it be checked while on board?
If it was the alternator, I doubt you would here a ticking sound coming from under the dash.. Diodes generally when they go bad, short or open, ticking sound would not come from that.
Ticking would mean something like a motor running or a relay opening and closing.
2013 Fords often had wiring harness issues, one real bad one is there is a harness on the driver side which has a connector that the pins get damaged from the vibration caused by applying and releasing your parking brake. Ford decided it was a good idea to solidly wire tie one side of the connector directly to the parking brake assy.. The fix to prevent damage to the connector was to remove the wire tie and tie the connector and cable to another wire harness above the brake assy..
One other wiring harness issue has been moisture getting into several of the wire harness connectors at the rear of the vehicle.. On trucks those connectors are above the spare tire..
It will be difficult to isolate where the drain is coming from, so many over the top complex computerized systems and some fuses are in and around the engine compartment along with inside the cabin..
