2005 Chevrolet Silvereado 1500 5.3 parasitic battery drain I am getting some weird readings on volt meter when I pull the battery fuse and the pcm B fuse any help would be appreciated. Battery drains over night, new battery new alternator. My cell is 832-727-0326

Does is have onstar? I had a 05 Tahoe and a 06 Cadillac Escalade that the onstar would drain the battery overnight. Pull the onstar fuse and see if it stops the drain.

No Onstar but, my dash cluster has the tach and temp not working, this seems to be a common problem where dash cluster goes crazy. I am pulling it out and ordered a refurbished one. I had a Ford F350 and the gas gauge would drop, then the drivers window would not work and some other weird stuff. Sent cluster in to be redone and reinstalled problem solved.

My Brother changed out his dash panel and his battery discharge went away. On my truck i removed the security system and my battery discharge went away. They're both Chevy 3500 Silverados Kenney Kelley

Yes have narrowed down to dash cluster, thanks to everyone that responded. Richard when I called Jason he stated that he could not repair it but I appreciate you response.

I disabled the under hood courtesy light to stop my discharge issues.

That must explains the battery drain on uncle's new Tahoe project. We'll check the Onstar after it returns from the installation of the new set of tires from 4Wheelonline plus the alignment.
