Truck info- 2016 3500 Cummins, 3 years and 4 months I’ve had it, 3 years and 6 months from build date
Ok, so for only the 2nd time ever since owning 4th gen rams. I got the “battery saver mode” message.... 1st time was 2 years ago (my fault, I went snowmobiling at -5*f and forgot to turn off the interior lights in my enclosed trailer and they stayed on for 7-8hrs with 4 old incandescent rv trailer light bulbs burning away) but after I started the truck, the message disappeared after about 25-30minutes of the truck idling and driving....
Now fast forward to tonight, remote start truck at work, let it warm up for about 10 minutes (34 outside) and get in truck to the message, but all the way home for 35 minutes of driving at 45-60mph most the way, and the message never disappeared? Truck started fine, I listened to it crank over at the man door like I always do.... so I’m guessing that I’ve got a toasted battery (or batteries being it’s a Cummins) probably gonna head over to Napa in town in the morning and see what their battery tester shows providing I don’t have to run 2hrs away to pick my dad up from the hospital (long story) but when the truck is off, does both batteries stay connected to each other, or does the computer isolate them?
