  • In this video we show a classic example of ground side voltage drop causing a no start on this 99 Chevy Tahoe. When you have more than one accessory that quits working all at the same time and a no start there is usually a common cause. A common power or a ground for example. Let's see what we find here. - Enjoy!

    Thanks for showing auto repair to your son. My dad had a Sinclair station when I was his age, back in the 1940's, I spent a lot of time at "work". I used to help pump customer's gas and when the driveway bell would "ding", I would go out and help putting gas in the cars, check the tires, wash windshields and check oil and "water" (radiator), when I got a little bigger, I would wait on our regular customers all by myself. Saturdays were car wash days where we washed them by hand, scrubbed the white wall tires with a wire brush and some or the "good stuff", chenicals, that Osha long ago banned. For fun, I would take an old (6 volt) battery, put it into a cardboard box and connect old headlights, horns, and switches to make them work and push them around on a "crawler". Later, I got my engineering degree and now I still put batteries in a cardboard box and hook up lights and switches. I learned so much by being around cars that rebuilding an engine and even an automatic transmission didn't seem like a big deal and other maintenance and troubleshooting is just routine. Now I am going on four score years and I still enjoy the IATN forums, Scanner Danner, and of course South Main Auto and not to be left out, Scotty Kilmer for laughs! Last summer it was time for a brake booster on my Chevy S-10 and whenthe job was done, the check engine light popped on, I got out my Innova scanner and checked fuel trims and it said vacuum leak and sure enough there was an old crusty vacuum line hanging out there in the breeze. Thanks for the memories. Bob L

      Robert Leifeld Very nice comment Robert. Many of our younger ones wouldn't b familiar with a score. To them it probably relates to a success. Twenty of course for me. At three score and eight. I converted my 53 Chevy truck to twelve volts. Changed the bulbs and that starter never worked better. Good memories with the battery stuff. Thank u!

      Paul Anderson...Amen to what he said!! Ivan has a lot of book smarts, and can say things a little better!! But you know your stuff!! You show us regularly that you know, you explain it very well, even tho you think it was a crappy description, it was as good or better than most!!
      I'm not able to, anymore, but I have been a wrench twister all of my life! It started when I was 8, and taking apart my new ten speed bike ( to the dismay of my parents)! I have a very good knowledge of mechanics, and have learned more from you, Ivan, Paul, and the Wells team, in the last little bit, than I already knew!! ETCG is not a favorite of mine!! (I won't even talk about that CAT BOX guy) While Paul is likely a better teacher, you are just as capable of DOING!! I've been through this exact thing, although not as bad, on a Jeep Cherokee. While I did fix it, and knew (because of you, Paul, Ivan, and let's not forget Will Robinson) what and how to look for, this video just helped me understand more of what I already knew, and fixed!! THANKS FOR WHAT YOU DO, DOCTOR O!!

  • @harveysmith100
    @harveysmith100 4 ปีที่แล้ว +3

    The voltage drop using the scope on a rope was mind blowing. Negative to negative and it lights up. That really helped to explain it for me.
    The scope on a rope are cheap enough to buy and are a fantastic tool.

  • @petersc1000
    @petersc1000 2 ปีที่แล้ว +5

    Love your video. Its terrifying the number of young factory trained techs who would have just swapped modules related to every light flickering rather than following an old school troubleshooting method. 125$ for an hour vs 5k for parts and you still got a broke truck. I love being gen x!

    It's really refreshing to see someone including their family or children in their work. My father did the same thing and gave me a love for mechanics that continues to this day. I did the same with my children. Even my daughter has basic knowledge of what is wrong and how to fix it and she has. Always good to have knowledge. Keep up the good work you explain it in terms that are perfect to understand. God bless and good luck

    I have two 98 chevy trucks one of which I bought new. I've replaced the ground straps on both of the trucks because they seem to corrode pretty fast. On the truck I bought new, it had two skinny ground straps from the factory. The replacements were the big thick ones like that Tahoe has. Before I even finished the video I knew the problem would be one of those straps. Nice job.

Ah! 2018 video the good old days when we had so much more freedom of expression for free thought and thinking and now if you say something that disparages a brand watch out - worse if you say the wrong anything... Gee whatever happened to us? But as I said So glad to see you again! I am stunned anyone could give you a thumbs down you are one of the greatest problem-solvers who shares real live information for others to learn....
    Crazy problem called to help someone last night with a 2011 Chevy Equinox when they turned the key the dashboard went dark (instrument cluster) cant take out of park. Release the key lights come back on. Battery has 12.4V. It was dark and late and I did not really have my stuff with me...This was just a test and go thing...called a friend who happened to be in the area and he jumped in - I suspect a wiring issue? Ground? He is leaning toward a Ignition key failure? Why? We did remove bezel by shifter and pushed on interlock switch to move into Neutral and tried to start - same indications. I really think we lost a Ground... It was running so says customer who claims he parked it for a while came back out and then no crank no start... fairly new battery... Interesting they tried to jump the battery... The guy was telling me his cable end from his car running was HOT to the touch but the cable connected to the non-starting car were Cool... Hmmm! Sure sounds like if there was no ground end of course that end would be cool because energy was not being passed through it therefore...because it would require a proper ground would it not to enable the flow of electrons which would then cause heat ...

  • @SteveP-vm1uc
    @SteveP-vm1uc 6 ปีที่แล้ว

    This was a lesson learned on all the early Japanese vehicles coming into the country 30+ years ago. Anytime one came in with ANY kind of wiring issue, I added fat braided grounds between the engine and body. Half the time the grounds from the factory were a wire with a pinch clip that was to scratch through the paint... Absolute garbage, but I was always the hero.. I like to ADD a ground to aluminum radiators as well. GM diesel trucks like to eat aluminum rads when the crap grounds failed. Back then they were upwards of $400. A $3.00 ground cable was all that was needed.

      I was "trained" the same way starting probably when I was maybe 6 or 7, but my dad and I used to take his old Orange body/White Top Jeepster to some land adjacent to the forner PRR Mainline that ran through town, I got to steer around with little risk of hitting anything (without power steering), and when I wasn't doing that, we would park and sit watching the trains go by.

      @johnaclark1 6 ปีที่แล้ว +3

      My dad always did his own auto repair. He was an amateur but pretty good at it, and I was always the helper. That's where I got the bug. I handed many wrenches and tools to the hand coming out from under the car, which teaches you what the different tools are, but the best fun was holding the light! Eric, you should make Gavin hold the light! It forces you to watch what the guy is doing. I did hear, "Dammit John, you're shining it my eye!" Sorry Dad...Great memories just the same, though.
      Gavin is definitely Mrs. O's mini-me. He looks just like her. I love seeing kids his age helping out. Kids need education but we need people who know how to use a wrench and this is where it starts. I hope we see him in more videos!

    Amazing how much electronics knowledge and equipment a tech needs these days to repair a car! You do a great job explaining in your vids too! One alternative explaining the voltage drop thing is from a "resistance" point of view using Ohms Law where Voltage = Current times Resistance. Simply put, for a given voltage and current, a larger voltage will be "induced" across a larger resistance. If the chassis and body were at the same "resistance" as the neg battery terminal (ground) there would be very little voltage drop. Take care

    Thanks for making such an excellent video. You explained clearly and showed use of several tools and pieces of test equipment. Don't be so hard on yourself and critical. This is a great TH-cam video. You're showing and teaching other folks out there. I've wrenched on and tinkered with old cars myself for many years, and sometimes I had poor Earth/ground connections causing problem. Your explanation was clear. I recall one car I had, had a leaking clutch slave cylinder. I knew about it and was carrying a spare. Suddenly it stopped working one day, so at the side of a river campground I quickly swapped over the brand new cylinder and bled the hydraulics and went on about my way. My car was fine, for awhile, until the season moved more towards Winter, colder etc, and this was an old DC generator car with only 22 amps available for charging (common among British cars up until the early 1970's). .Then I noticed my accelerator ("gas pedal") kept jamming on, I'd have to kill the ignition switch, raise the bonnet ("hood") and free up the accelerator cable. Turns out, that in my hurry to change the clutch slave cylinder at the roadside, I had failed to connect the main Earthing cable linking the engine block to the body. Electricity was getting through, enough to start it and run the lights etc, but the Earth return path was through the throttle cable and the carburettor, I re-installed the freely hanging grounding cable where it attached sharing a clutch slave cylinder mounting bolt, and lubricated the accelerator cable and all was ok again !

    "I probably could have been electrocuted".
    If you dont have at least 10 life experiences where that phrase applies, there is still much learning to be done.
    Great vid again Mr O.
    Stay gold.

    This video helps point me in a direction. Thank you. Mine is an 05. Sat in the heat of the summer. Got the battery jumped. Drove it around for 20 minutes. Pulled in front of the house. Won't start again. The gauge was not stable while driving nor while I let it idle for ten minutes. I was hoping to drive this because my other car needs the wheel hub assembly replaced which is the plan for this weekend. So. I guess I am borrowing my son's car.

    GTO has a comb over, laugh out loud Funny. You explained voltage drop perfectly and backed it up with a visual. Until I started watching automotive repair videos this concept escaped me. Now I totally get it.

      Wyatt, same here. I never understood voltage drop, nor did I know much about it until the last couple of years. Now I can't believe I could do any car electrical repair without knowing it. I also used to use a volt meter to test tail light circuits and could never figure out why I could have 12V at a tail light yet it still wouldn't work. Between Eric O, ScannerDanner, and Ivan, I've been able to really step up my game.

    I've replaced numerous starters on Silverado's where the braided "wire" between the solenoid and starter motor has rotted and broken in half causing the starter to fail. Seeing this video and the ground strap all messed up reminded me of that.

    You nailed that one Eric. I remember the 1980s UK Ford cars (a couple of models were sold Stateside under the ill-fated Merkur brand) doing a similar thing when the indicators (flashers) were illuminated the brake lights would go dim and we knew that was due to a bad earth (ground). I've just had to replace the ground wires on my Triumph which will be featured in an upcoming video of mine.

  • @rpierce62

    I had my 1997 Toyota Camry in storage for about six months, the battery was old and drain down to a slow crank no start. Then it started flickering like that truck , so I disconnected the battery ground waited 5 seconds and connected it. When I cranked the car it started flickering again. Disconnected the ground again and this time I drained the system by turning the ignition to start for a couple of seconds. After that I connected a new battery to it and it started right up without any problems and still no problems. I have 3 Camrys and the 1999 and 2001 haven't done this but my 93 Landcruiser does, I bought it like that and it looks like it's got something to do with the oem alarm system or something.
    Good video 👍

    I do wish you had taken us all the way to the bad connection though, then you could have shown the pd drop across the crusty connection itself. It is worth noting also, that the closer you get to the intermittent connection the more careful to be in disturbing it - one touch and it could stay made which is the worst outcome...
