Update. Won't bore everyone with everything I've tested, including with a neighbor who use to work for GM and still has his Tech 2. It appears that I had an intermittent faulty brake light switch that would sometimes turn on the brake lights if it sat outside in the extreme hot sun all day...
so been watching this for about 45 minutes and hovers right around here. so is something randomly turning on? this can't be draining a battery within 2 days.
currently it has no battery in it since it is completely dead and won't take a charge. it's sitting on my bench until I go to the store.
I would argue my meter is fairly accurate. it shows around 12.3 to 12.7 when testing all my other vehicle batteries when I test the alternator output on...
I'll definitely do a parasitic draw diag as soon as I have the correct tools. the only multimeter I have left that's halfway decent can't measure amps. the only test I can do until then is measure voltage drop across the fuses. not the best way to test, but a large power consumption should be...
Well to add insult to injury, I had a 4-amp battery maintainer connected since Wednesday night. The display showed it was charging and doing its job that night. Checked it the next morning and it was still showing good. Tonight, I go out and it's flashing its error code, the battery is...
thanks for the tips! I would love to use my test light.....except I kinda broke it awhile back....oops, lol. looks like I have a good excuse to go tool shopping 😀
Hoping to get some insight from someone smarter than me. 2002 Sierra 1500 4x4 w/ 5.3, 310,000 miles. mechanically this truck still runs amazing, everything still works, and no rust. I've owned it for about 4 years now as a "first time" vehicle for my kids. I've been tinkering/fixing some...
Yes, the legendary vortec 5.7 :happy:. There's no misfire, no cel. This engine runs extremely well, doesn't even leak. It passed emissions test a few months ago with flying colors. I suspect the dairy farm this came from kept a good maintenance schedule on their equipment, because other than...
So my project truck has been running fantastic these past several months since I bought it. Biggest "repair" I've had to do is replace the AC system. Works like brand new now, will freeze you out even in these 105 degree days.
So one day last week I took the truck for a drive and it wouldn't...
So I really wasn't looking for a project truck. Was actually just keeping an eye on marketplace for something for my next kid getting ready to get his license. However this one showed up that was just too good to pass up. It belonged to a dairy farm and my best guess is it must have been...
So here's the final follow up. I figured it out....for the most part. Before all this happened I had installed on of those aftermarket "all 4 on high beams" kit. basically extra relays plugged into an aux block to use the hot wire from the high beam to trigger the other relay to keep the low...
Ok, so here's the follow up. The cause was the 15amp fuse under the hood for driver's headlight was blown. At least I think it solved it......I'm not entirely convinced. I don't get to tinker on the truck much since it is what I gave my son to drive and it's about a 5 hr drive away. We've...
Ya, I know it's been awhile. Life threw a big monkey wrench at me a few years ago with a divorce and priorities in my life shifted a bit. I don't spend much time on a computer after work anymore.
I suspect a grounding issue too. I was wondering if there was a specific ground wire location...
few months ago I bought a 2002 GMC Sierra 1500 for my son. Not a perfect truck at 300,000 miles, but everything works.....at least until last week. Just out of the blue when you turn on the low beams, the driver's side high beam and passenger side low and high come. When you switch to high...
ok, long time since I posted this. Wanted to give an update so there's an answer in this thread. Cables were all stretched. I actually paid a shop to replace the cables because I was super busy this summer with some major projects around the place, including getting my NEW SHOP built...
So I had a little time this evening to play around with the system. I'm leaning towards the pedal spring/auto adjust mechanism has broken. I can find nothing wrong with any components at the rear tires. However I can grab the cable underneath where it comes out from the cab and actually pull...
Tried it.... no luck.
The more I've been digging into this I've found that what has probably happened is my auto adjuster has stopped working properly. Still trying to figure out how to fix it without having to take the pedal out and/or replacing the pedal. The pedal assembly is only $50 on...
