Truck won't start

Truck won't start
I have a 2001 Chevy Silverado 2500 HD 4WD. It is a short bed, 6.0 litre, V8, extended cab LS version.
I have had it since 2001, we are the 2nd owners. Other than an issue with with the fuel pump and the transfer case, it's been a fabulous truck.I went to the dump last week, came home and parked my truck. The following morning, I went out to drive it to work and it wouldn't start.I put the starter motor back in and checked the battery dead. Used the trickle charger on it and tried to start it and it wouldn't start. But everything turned on ok except for starting. I bought a brand new battery and it still wouldn't start.I have checked the fuses, they all looked fine. Plus since it works on a relay, it wouldn't click when I try to start my truck if the fuses were out.I pulled out the starter motor and it tested fine.Based on what I know, the alternator should be fine and I assume since there seems to be an error message on my console for every little thing that there would be something for the alternator too.I have even checked the cabling on my secondary battery, it is fine and the connections are tight.I replaced both sets of battery cables less than a year ago so they are new.Any more suggestions? I am at my wits end on this one.Thanks!

I took it out and took it to Auto Zone. He tested it 6 times each time it seems that it came out in great condition. It tested 3 areas: the voltage, the current and the drive exstension. It passed all 3 every single time. Is it possible for the solenoid to be shot and still pass?
Thank you for your response!

So I had my friend come over to help me troubleshoot. We found something new.
There is a clicking sound; which I assumed was coming from my starter motor; it is not. There is a little box against the firewall behind my auxillary battery. The cables go directly from it to my starter and to my aux. Battery so I assume it has something to do with this. I can't really explain it very well so I took several photos. Any ideas?

Sorry, accidentally hit reply. Here are the photos.
The rectangular box to the lower left has the cables going to starter and aux battery..
This is the box that clicks.
This is the writing/sticker on that box. I cannot find anything in my haynes manual that seems to describe this.

Was this vehicle made in Canada? My take is the relay coil is the issue. If it were me, I'd take a large screwdriver across the two terminal's with the key switch on, just saying what I'd do.

If it's wired to parrallel both batteries during crank, yes it could be. Being a 6l, I'd think it should crank with a single good battery with the proper cca.

No. This is not an aftermarket add on. I bought thr truck and it came with the Auxillary batrery set up this way. I ordered both relays to replace to see what this is and hopefully this works. Thank you though for the ideas, you have been helpful.
