<div class="bbWrapper">So I’ve seen posts about batteries and starters. My 2022 bighorn Cummins had the push button click today.. everything worked, just wouldn’t turn over. 100A boost from charger and wouldn’t turn over. Jumper cables to my son’s mustang and it eventually started. Batteries showed 11.4V before and 13.7 with truck running. Parts store “load tested” then and they both show good. And coincidentally my auto up drivers window doesn’t auto up. Any ideas short of a dealer visit ?</div>

<div class="bbWrapper">11.4V is beyond dead. <br /> <br /> You need to figure out of something was left on, or if you had a battery fail. <br /> <br /> Charge them for 24-36 hours then let them sit without the charger for 4 hours. What’s the voltage then?</div>
 
<div class="bbWrapper">May want to check to make sure the truck is correctly powering down when you walk away from it. There were some issues with trucks staying partially “awake” after the key was taken away from the vehicle. You can usually tell if it’s not fully powered down by looking at the EViC. It won’t be completely black. Also check to make sure your truck doesn’t fall under the TSB for the non-conductive nut on the starter.</div>
