Hi there. 2014 Ram Big Horn 1500 4x4 crew cab with the 5.7 hemi. I have replaced the battery, alternator and the dealership installed a new PCM. I still have a low voltage message, and battery light is on. After 21 hours of diagnostic time at the dealership, they had no results, and tried to make me pay for the PCM when I didn't authorize it. They bought it as the "tech" was swapping parts instead of finding the issue. I'm not ragging on the tech..but I still have this issue, and the truck runs drives and starts fine. Never once dead or slow. I have cleaned up every ground up rop, inside and underneath the truck. The sensors on the battery are fine, all fuses are fine, nothing has ever been butchered anywhere on the truck. All connectors and pigtails appear perfectly clean, and tight. Every fuse tests good. I have a single battery. I need help please!
