If the battery is charged but has no power to the items you describe it may be a blown fuse on the battery. There are three:
100amp, 850w Engine Fan
125amp, Power Steering
250amp, Main Power Source

And if one is blown, maybe your "dead " battery isn't dead.

Sounds like what @John Jensen was mentioning. Here is a link to what the zcase fuses look like.

I was wrong about having three fuses like the HDs. It has two. Here is pic of a 2018

My 2015 1500 ED has 3. There are 3 in that pic too.

Yep, you are correct. My 2016 has three as well. I received bad info, thanks for correcting me - appreciated!

How do you check or change out those fuses

How do you check or change out those fuses

Same as you would check any fuse, with a meter
Change out with a wrench
