    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...
  2. Duramax 6600 6.6L V8 Diesel
    How do I jump start a 2008 Silverado 2500 Turbo Diesel? It has 2 batteries in the engine compartment, one up front on driver side, one back on passenger side. Which to use? I have a Dewalt 1000 watt power source. Is this sufficient for a jump start?

    Little by little im noticing my 2013 HD 6.0 crank & start up weaker & weaker. The battery is atleast a couple years old & I'm willing to bet it's time for a new one. I definitely want an AGM battery. I was thinking about picking up one of those Optima yellow or red top batteries (I forget which...

    I'm looking for some input on battery warmers, specifically what wattage blanket or warmer should I get for my 2008 Silverado 1500 LS with a 4.8L engine. Also, any experiences with heated, silicon mats for under the battery or is a wrap-around blanket the way to go? I'm in the Plains states...

    Yesterday while out and about I got a prompt on the dash to replace the key fob battery soon. I didn’t think much of it and figured I had batteries at home and could change it later. I was at a store and came out to start my truck but it was completely dead. No display on the dash like it...
  6. 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...

    Bit of a weird one here, and hoping you guys can help. I have a 2003 Sierra 5.3L Automatic Z71 with 174K miles. The other day I went to start it up (it was already warmed up) and I noticed my radio, AC, door locks, windows, and all right gauges not working, nor the drive selection or 4WD...

Past few weeks I’ll be driving and my gauge cluster will light up like crazy and my battery light with come on and everything kind of stutters but nothing shut off completely and then everything is fine.

    On my 2018 Silverado, I noticed the battery tray in the front left of the vehicle and would like to add the factory system that could have came with it. I will be doing some towing and will be adding 12v accessories to my system and don't want to overload/drain cranking battery. 1) Can this be...
  11. EcoTec 5.3L V8
    We have a 2019 LD, with around 100,000 miles. The truck has been having starting issues. It won’t turn over until about 10-15 minutes of trying. Then once it goes again, will start just fine for a few days. Then sporadically take several minutes of turning the key to get it to turn over again...
  12. Vortec 5300 5.3L V8
    we have a 2002 chevy silverado . When we start the check oil pressure light comes on, once it warms up light goes off and oil pressure gauge starts working. This has been going on for awhile. Weve also been having to charge the battery after its been sitting for 24hrs. Now after we charge...
  13. Vortec 6000 6.0L V8
    2004 Silverado 2500HD 6.0L. I was driving down the road minding my own business when all the sudden my security "theft" light came on along with the battery light, with those two lights on the oil press, fuel, and temp gauges went to zero. I maintained all power otherwise it would range anywhere...

    Hello so just 3 days ago I ran a power invertor off of the truck battery to power an air compressor. The power invertor is no longer attached to the battery, I only needed to use it on a particular jobsite. just this morning when I was leaving for work, I started the truck up and made it about...

    So a few months ago I had the issue where you turn the key, it clicks, but nothing happens. I took the negative ground wire from the battery off and cleaned the connection to the body and it seemed to help. I replaced the battery at the time too and it seemed to fix everything up until about 2...

    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...
