When a guy on YouTube explains things better than most teachers

As a ham radio operator, I will tell you another place you can eliminate radio noise, and the factory does NOT do this for you. Ground your tailpipe! It acts as an antenna putting out noise. Try a strap hose clamped toward the back of your pipe to chassis.

Jan 2024. My brother in laws 2003 Chevy 1500 PIckup had exact same problem. Bless you for describing this problem to us plebes. You led us to think ground problem and helped us narrow down a bad electrical ground. Thank you thank you thank you! Mechanic wanted $300 just to look at it and we almost considered going to a mechanic but then this video allowed us to problem solve it!

[joelquaintance]

I'm 71 and you explained ground problems like a PRO i.e. like you been doing this for 50 years. Good Job. Thanks.

3:50 - I honestly never thought to use my phone as an extra set of eyes like that. Awesome tip!!

[mkatt]

Hey man, I just wanted to say you so much for taking the time and effort to show us step by step instructions, along with awesome visual clarity on the locations of the grounds. Saved my bacon man

[chadrose]

Only one you left out is Negative off the battery to the block, very important one as well
Great video bro

[hendy]

As a time and headache saver you don’t have to mount the ground strap to the original spot on the back of the block. You can simply run it to the alternator bracket and bolt it down there.

You have a talent for teaching. Great video! To the point and slow enough, so this old man can understand it! In my early years, I worked on cars for 20 years!

[AnthonyStLouis-bidl]

I'm waiting for the rain to piss off but these are all of my symptoms that I've been scratching my head about for months now thank you dude

[dklef]

I can't believe someone posted EXACTLY how to fix all these dam problems! The video was PERFECT. You got right to the point and showed exactly what, when, and how. I actually had the engine ground to chasi strip attached but it was so frayed and gunked up with oil on the engine block part (where you mentioned yours was burned off) it was creating havoc with everything electrical in the truck. Over a year and a half with these probz now they're gone. Thanks Brother!

Got my engine replace over 10 yrs ago. I always wondered what that strap was for after it was just left hanging. I ran it to my alternators ground bracket and it fixed all my electric issues. My lights don't dim now when the bass hits. Lights don't dim when I use my windows. Thanks for the video. This was my win for the day.

[mbreckwoldt]

bad grounds can trigger all kinds of electrical problems. Good video, thanks

[TraciRNump]

Thank you do this! I have had a 2000 gmc sierra that needed this all along. Now I have a 2001 that I am going to replace as mine looks worn, window lags, and lights flash. You explained it to where I can do it myself. Thanks so much!

Dude. Thanks for video. My 2003 Z71 suburban had been acting up for last three weeks. First week, the 4WD trouble code began appearing. The second week, my lights started operation weird and I got a security indicator in the dash. Third, my car would not start. I would jump it and it would drive but very weak, with power fluctuation. Checked all grounds and they were good. Battery check was good; battery only 8 months old. Figured alternator was the issue. Good thing is I have a donor suburban at my house and it had a good alternator. I changed the alternator and while reconnecting the negative battery cable I noticed my hand was full of oxidation particles. I pulled the rubber cover off the negative cable terminal and the whole thing was with oxidation. You couldn’t tell from looking at it with the rubber at the terminal end on. Once I cleaned off the entire negative terminal and screwed it back in, the vehicle worked perfect. Tried it with both alternators and they are both working. It was the battery ground cable. Luckily, when reattaching neg cable to battery I noticed those oxidation particles coming out. The battery was still charging but could not start the car. Crazy stuff that can make you go crazy. Thanks again for your video.

dam awesome video. I broke mine when I changed my oil pressure sensor on my 2005 sierra. and my "service brake system" light came on. I bet it has to do something with this. ground wire.

thanks for the video and going the extra mile showing the location

[LeidlDiroert]

Thanks, super helpful, also 900 ft lbs was the correct torque spec

[OakLawnSpeedShop]

Good vid. Thank you. Recommend cleaning where the alternator power wire and positive meet in the red junction. Then lube with dielectric grease.

Great info! Bad grounds can cause all kinds of weird problems. Make sure they're good before troubleshooting any other electrical issues. Good tip on cleaning off that paint from the hood bolt. Many people would have missed or skipped that step.
