    Swapped the batteries and condition does not show its face. WTF. Did a key on with each side disconnected one at a time and never saw the SBS message. Lights dimmed pretty hard I thought it might happen but no. Wonder if maybe that means it is grounding issue and the "good" battery had enough...

    No but I can certainly try that. I will do that and report back. I do have 2 other 750/800 CCA batteries I can always toss in and try as well. One is brand new off the shelf but the other is older. @TheBac You would be the first to publicly declare alternator I think.

    I went back outside one more time to check something. I unplugged the negative from the good battery and plugged the negative into the "bad" one. Key on and I have my condition. "Service Brake System", @Chevy1925 I even checked the codes for you and nothing. I have three, one for headlamp...

    Well now it must be a draw for sure. 12.4 a few hours later when I went to check before I did the test. One thing I must ask, does cold weather affect a batteries voltage? This is a condition that I only ever see in the cold. 40 or so. Right now I am actually NOT having the condition with only...

    Got busy yesterday. This morning I checked the batteries, 12.45 on the suspected bad and 12.65 on the suspected good. Both went down about the same amount however that 12.45 is down below where I would think batteries should be charged at. I did not crank them. Family should be here for the...

    @1FastBrick I currently have three AAA batteries. One in my Silverado which has been in there for maybe 2 years now? And then these two.

    Tonight I will try and start it on one battery (The one I believe to be the good one). If it starts I will leave it and check voltage at the alternator. Next I will swap batteries and try to start it on the one I think is bad.

    @2004LB7 Not yet. I have been too busy to spend time on it. I do plan on doing it at some point. @Ron Nielson I am not sure I follow completely. So put them both in but undo pos on one. Test in the morning and record data. Swap batteries (physically or just plug one pos in and remove the other...

    Perhaps what I should do after I leave it sitting for a couple of days outside is throw it in the truck by itself and see what happens. The battery that is in there now seems fine. I have yet to see the brake message on the dash.

    Apparently the 0V battery was fine and charged back up and passed the load test. I am going to leave it out over the next few days and check the voltage just to see. At O'Reilly it only charged up to 12.3V apparently. If it is not the battery then I will start checking the grounds. Put the test...

    Driver side pos. terminal bolt replaced with a Schumacher BAF-STB. I did check the cables and there was two flecks of the green on there. Cables looked fine to me, should have grabbed a picture but I didn't... Did clean it but my battery terminal cleaner seems either not to work or it did not...

    I will be replacing the batteries in pairs. I was not certain if I could run the truck off of one battery.

    I actually just went out and checked something. I have had the driver battery out of the truck for a few days now. Passenger battery was left in the truck. Pulled the passenger battery out and no shit 0 V. Thought my meter was broken so I checked the sitting battery and it is still at 12.7. Is...

    @Chevy1925 Yes that is normally what I do. Only have codes for my seat heaters. I had a bit too much to drink tonight so I didn't get to doing anything productive today

    Decent Autel. It is a bidirectional. I have not tried to go into the module by itself.
