I've worked on vehicles for a long time...usually battery and alternators are pretty straight forward. So a couple of weeks ago my wife sends me a photo of here dash with a "Battery Safer Active" message. I've looked it up and the battery or alternator are the top 2 suspects as I would have guessed. The battery was replaced back in Oct 24 so I've had everything checked and they say its good. I pulled the positive battery terminal while it was running. There was a slight hesitation, but the engine kept running. So it was driven another week without incident. A few days ago my wife sends me another picture of the guages. The battery guage was reading a bit low as it usually hovers around 14VDC. What she showed me was around 12. I told her to take it to Orielly's since thats where we got the battery. The guy told her that everything read good on the battery, but the alternator was around 12.5 VDC output so the next day I replaced the alternator. Drove it around for about a half hour and it held strong at 14. Three days later and the guage is back at 12 VDC. This would be easier to diagnose if she was here, but she drove it 3 hours away and concerned about it's reliability.
Has anyone else run into this type of problem? Our Tahoe has about 160k miles so a ground wire wouldn't be out of the question if it was corroded or loose. Just trying to see if there's something I'm missing. Thanks in advance.
