    Hey! So, 2014 Silverado w/ 5.3L, I think it's the eco? Anyhow, it's running 120k ish, has new battery, new alternator, same issue w/ different new battery. It was happening on old alternator as well, but figured I'd try. After about 2wks the battery will be dead. Once its getting close to...

    I’ve got a 2011 Sierra 5.3L 4x4. I’ve noticed (for a while now) that the alternator is overcharging. While cruising down the interstate, I’ll see the meter on the dash anywhere from ~13V to 16V. It doesn’t jump rapidly, but it does move up and down steadily. More often than not, I’d say it’s...
  3. Vortec 5300 5.3L V8
    So I just noticed this the other day. Whenever I'm at idle the voltmeter will shake in the middle of the 14. Then when I start to move it won't shake anymore. There was even one point when I was at idle and my dash lights and headlights were flickering a tad bit until I pressed the pedal. Any...

    My 07 new body style Silverado LTZ has given me intermittent starting issues for a few months now. The truck had a new motor put in around 60k miles ago, and when I got it around 10k miles ago I plugged in a Range AFM/DOD delete. It starts with putting the key in accessory, all dash lights...

    So I’ve been having this issue where my gauge cluster will light up and lose power for a second then come back on, I only have this issue when I play music. I have a pretty demanding sound system that takes up a lot of power but I’ve had it for 3 years and haven’t had any issues from it. Now I...

    I got a new to me 2014 2500 with the 6.0l. This is my first year plowing with it and the alternator seems to be struggling with it at night. Between upgraded plow lights, the oversized v plow, wipers and heat going the alternator doesn't seem happy. Im setting my truck up for off grid work so it...

    I have an 07 NNBS Silverado and I've been getting the "Service Battery Charging System" message on the dash along with the battery light. At first, it happened every so often and the light would go away after a few mins of driving. Now, most recently, its been more consistent and the light has...
