No gauge function

After a battery failure and replacement with new batteries I have no gauge function, dash lites all work

What truck? Is it an 06? Tell us about your truck, mods, etc.

Sounds like a fuse blown somewhere, did you spill some of that white lightening in the truck? bg

It's an 05' 3500 4/4, had a catastrophic battery failure, put in new batteries & the truck runs great but the gauges won't work. Also I cleared all codes and recovered the ECM with my Smarty

I don't have a manual on anything that new, 99 is last one. Looks like some of the instruments come through the PCM or ECM. If the batteries burst you may have some bad connections where the wires come through the firewall or where they plug into the ECM/PCM. bg
