I believe this problem is older than just the later models. I have a 2012 F350, and also see very limited current that charges the TC batteries. Even after an all day drive (8 hrs), the charge is very limited.
I’ve heard of ‘smart’ alternator design by Ford that makes this limited charge a ‘feature’.
I do believe that the 4 gauge wiring/solenoid/fuse setup will bypass the poor design, but be aware of warranty issues that Ford could evoke.
Also be aware that any additional options like towing packages, MAY require an updated Basic Computer Module (BCM), which isn’t cheap. And you’ll need new keys to go along with the BCM, which also aren’t cheap. Off subject, but I had to have a BCM changed, because the right rear turn signal didn’t work – $650.
I’ve gone with the solar solution that makes this problem less of an issue. Love the F350, and there’s a reason there are tons of them out there.
Good info in the forum, as usual.
