2007 Ram 2500 5.9 Batteries dead, low voltage on dash gauge

Customer Question

2007 Ram 2500 5.9 Batteries dead, low voltage on dash gauge Check gauges light on but no check engine light
JA: Thanks. Can you give me any more details about your issue?
Customer: Truck has been running just fine. Two days ago I went to drive it and it wouldn't start. I thought I left something on but couldn't find anything. I charged the batteries enough to start it. Started it and took it on a drive. Then parked it and tried to start it later that night, it wouldn't start. I jumped it again and the voltage gauge showed low like around 9-11 v Then the check gauges light came on. I batteries have been charging and tested out to be in good shape

I bought a new alternator etc... But the alternator came with a sheet describing a TSB 18-001-07 regarding my year/model of truck stating that my problem may be the PCM programming.

Thank you for the VIN! So now the vehicle has low power and does not even crank over correct?

Do the headlight and or dome lights work?

Expert:  Amedee replied 1 year ago.

Were the batteries replaced? If not, have they been load tested using a battery tester?

Expert:  Amedee replied 1 year ago.

Maybe you just have bad batteries.. or a bad connection at or after the batteries. Can you tell me what the battery voltage is at now on both of the batteries?

Expert:  Amedee replied 1 year ago.

How about the voltage on fuse number 1 and 2 in the power distribution center udner the hood?

Customer: replied 1 year ago.
Batteries are two years old. They tested out at 12.6v each.
Customer: replied 1 year ago.
Unable to test the voltage at those fuses, I don't have truck with me
Customer: replied 1 year ago.
The dome lights work only after I recharge the batteries for a while. Otherwise he entire truck is dead after even a ten minute drive
Expert:  Amedee replied 1 year ago.

Are you able to check the voltage on the fuse and reply back? Or can you call me when your at the truck so I can walk you through this diagnoses?
