Hey all. I am new to this site and recently purchased a 2012 Silverado Z-71 with the All Star Edition. I noticed my battery gauge needle is moving more than I have ever seen one move before. It appears the needle fluctuates between 12 and 15 or volts. The battery gauges on most vehicles I have owned stays around 13 to 14 volts and doesn't move much unless something that consumes a lot of power is turned on. Mine does this with nothing additional running on the truck other than the radio and a/c. This morning the needle was about 1 volt below (13 volts) the middle mark (14 volts) on the gauge. I noticed it, turned the truck off, restarted the truck and the needle went about 1 volt above (15 volts) the middle mark of 14 volts. Has anyone else noticed this in their trucks? BTW, this won't be my first post, gain info, then bail out. Someone pulled out in front of me and totaled my 84 GMC truck. I was/am very active in another forum that was started primarily for older trucks. Nonetheless, that truck is gone and I am looking for new forums to get involved with that have lots of info for newer trucks. Thanks!
