I have a 2019 Ram 5500 and am having battery and or alternator issues. Battery went dead and found that the alternator shows 13.6 volts. Not enough. I get the truck home after jumping it and notice that the led display that lights up and gives instructions on how to start your truck will not stay off with the truck locked and everything off and the key fob in the house. I watched it and it goes out but pops right back on. Any fixes or idea what the issue may be? Frustrating, this is the second Ram I've owned with similar issues relating to electrical.
