Swapped in stock tune now batteries wont charge light on

[manteray]

I just swapped in my stock tune before taking the truck into the dealer and now my battery light and battery wont charge indicator is on. I also tried another copy of my stock file with the same results. Anyone know how I can fix this. and it wasn't on before I swapped tunes today(had my tow tune on it till now). 2006 LBZ stock
thanks for any help you can give

I would ask the dealer. I doubt it is efilive related. Coincidental failure possibly. What does your battery voltage read during idle?

Battery Voltage was dropping even with the truck running, ended up changing out the alternator and it fixed it. Must have just been a fluke that it happened when I swapped tune files. thanks for the reply
