    2014 Tahoe 177k miles. So the last few days, it’s been getting pretty cold and I noticed my truck kinda bogs down like it’s gonna stall for a split second when first starting it and than rpm go back up. I did a battery and alternator test with my OBD reader and it passed on battery but...

    Hey all! I recently replaced my battery and my alternator and now my voltage gauge is bouncing around and all lights (headlights and interior lights) are flickering while driving and while at idle.

    New thread - Electrical issues

    Hey again y'all. I chased a drain in the following thread but it has returned. At this point, I have no power at driver or passenger's door except that I can move the driver's mirror as expected.

    Alternator and battery questions 2014 Tahoe LT

    Intermittent chirp I’ve always had that I think comes from the alternator, it’s not to loud. I just changed idler pulley, so I don’t think it is that. My battery voltage is always eratic, it’s always different when I start the truck, but the voltage will stay between 13.4 and 15.2… Valvoline...

    Should I go dual battery?

    I’ve got a 06 Tahoe z71 and I want to add a better radio and better speakers and put in a wall outlet like a 110v socket in. I figured I wouldn’t need dual battery for the radio and speakers, but should I get it if I put in the outlet?
