Not that this is normal, but my truck (2020 6.2 RST) wasn’t charging the battery on my dump trailer. I removed the fuse and saw that it was good. All I can say is that putting the fuse back in fixed the problem. I bought a 7 pin connector tester off of Amazon for 8 bucks. It was delivered the next day, so quick turn around. Now, the pin has power to it continuously, as it should. I know it seems impossible, but I’ve seen crazier ****** having been an electronic technician in the NAVY for 11 years. 90% of electrical problems are cabling. Fuses are considered part of that in my book.
