New guy, just got out of the truck and heard this high whining sound that eventually goes away as it warms up.
Truck has 303,563 so far and I hope to go at least 500,000.
I'm guessing alternator as I feel a grinding when I touch it as it makes the noise.
Original engine and most parts. Trans at 165,000 nothing else major
I'm planning on upgrading my truck with a simple audio system, maybe 2 LED light bars, plus accessories.
1.For the audio system
Simply replace all the stock speakers with higher quality plus an amp. For the head unit, I'm looking into the 10in screen models. Also I found some bed storage bins that come with speakers as well which are perfect for tailgating.
A light bar, maybe 2, and some other lighting that I haven't decided on yet.
Train horn+air hose kit that comes with certain models.
I have a solar panel that I got on ebay that I use to maintain the battery since I'm always stopping and going due to my work. But I'm planning on upgrading the alternator, big 3 ground kit, and a second battery.
What do you guys think??
So it started happening to me about a week ago, my truck would just randomly not start. When it first happened, it would struggle to turn over. I said no problem and just bought a new battery for it. About 3 days after that, I went to the store and was only in there for about 2 minutes and got back in my truck and out of nowhere, nothing happened, not even a click. I checked my connections as best as I could, and eventually had to get jumped. Tried it again as soon as i got home, turned it off, immediately tried to turn it on and once again, not even my dash lights were coming up. I jumped it and took my negative off to see if it were the alternator or not but it kept running. Any thoughts?
Hello everyone, new member here from Tucson. I recently purchased a Yukon, and i suspect a bad alternator, but i am new to TBI so this may be normal behavior. When cold, im pulling a solid 14v, as the truck warms up, the voltage drops to 12v. With lights and a/c running its 11v, and it seems to have nothing to do with rpm. The truck has a new 600/750 CCA battery. Is this normal behavior for a 350 TBI? Thank you.
I'm still learning here and am wondering about something I ran across recently. (Sincere thanks to everyone on here who has already been a huge help to me thus far!)
I understand that the increased-power/heavy duty alternator (part number 22949467) appears to have made its way into many 2015 CrewCab models and other models with the snow plow-prep package. It seems tied to RPO 5W4 (which, in several sources I've researched, ties back to "VEHICLE SPECIAL SERVICE, MUNICIPAL" - makes sense for a snow plow-prep package).
I scored a fantastic deal on one of these units for my 2014 Silverado LTZ Z71 DoubleCab 4X4. Being an LTZ, my Silverado has most of the current-drawing goodies. It also is about to have the factory Kicker subwoofer upgrade kit, an on-board air compressor (Viair 40049) and a full front/rear dashcam set-up with active/passive monitoring. I've also just paired all of this with a brand new AC Delco AGM deep-cycle higher output battery (P/N 94RAGM).
In other words, all of the further current-drawing goodies are here and ready to be installed when the weather here gets a bit warmer. Are my electrical upgrades going to be good enough to support an already high current use truck with an extra draw or three?
