2014 battery distribution box

[Burke8810]

Hi everyone. Went to start my 2014 Chevy Silverado this morning. Battery was dead it’s been getting weaker the past few days. Go buy a new one as I’m installing the negative battery cable I let the ratchet touch the stud for #4 on the battery distribution block. Started the truck and it says service power steering pump. So I assume I must have blown something when I touched that stud. I see each stud is labeled 1,2,3,4 so on #3 is empty nothing connected to it so I take the connection from 4 put it on 3 and now my power steering works. So I’m wondering if I can just leave it there and still use the truck because the only replacement part I can find takes over a week to get here.but #4 is labeled 175a and #3 is labeled 125a. I drove it to town let it sit about an hour tried to start it and it said something about the security system that I’ve never seen before turned the key off and back on now it’s fine. Any suggestions please help

These trucks do strange things when you change the battery out. Try to put it back to stock config on the battery box and see if it’s fixed.

I believe the large box on top of the battery is generally a large fuse-able link with various fuses as they are numbered.  But then I know that there is also an electrical harness that plugs into it, so I can't say for sure what function that aspect of it has.

My #3 position is empty as well.
