I’m not completely up to date with the newer models but I am trying to get there. I have a 2017 silverado 1500 4x4 and I’m having some charging issues. I changed the alternator and battery both are new but the battery isn’t charging. I’ve tried replacing the wire between alternator and battery, checked wiring harness and wires. But it will not charge. Any help is appreciated. Also the old battery and old alternator tested good when pulled out of the truck and tested
