In this video we prove again the power of the visual inspection. We see here it is used to nail an intermittent complaint from the customer of the battery light coming on. This vehicle was taken to the deal and has had several alternators and batteries replaced. However if they had just taken a look at it, they would have seen the issue. -Enjoy!

    Great video! My truck had same issue. My question is how did you fix the wire? I cut and spliced my wire and I still have battery light on. New battery and alternator. Just curious how you fixed the wire

    Thank u for this video. This helped me to figure out the same problem with my customers F-150! He was ready to throw in alternator but when o started looking at it I noticed the #45 fuse (alternator sensor) kept blowing out after driving for a while. I Knew it had a short somewhere and when I got on YouTube just like magic your video popped up!! It was the exact same location where his short was

    Found the same thing on my 2011 f150 -5.0 …… thanks to you sir!!!!! 👍🏼💯

    Eric O. You have taught this Master to be your student. Thank you for all your posts!!! You make us all better tech’s

    the ecu receives the signal from the eld which sends the signal to the alternator or pcm>alternator depending on the vehicle

  8. Avataaar/Circle Created with python_avatars Michael Janz says:

    I have the same issue. My mechanic says it'll take 8 hrs to get the wiring harness out, because he can't get in there. Was it enough to just take those bolts out to remove the harness? Do you have a video as to how you did that?

    FORD is an acronym for “Fix or repair daily”

    What a conundrum: Your customer base growing exponentially as word gets out about your thorough troubleshooting and repair skills,and dropping just as rapidly as customers start watching your channel and realize that if you can do it they can do it….

  11. Avataaar/Circle Created with python_avatars Joseph Belmares III says:

    Great video love your approach to repairing ppls vehicles

  12. Avataaar/Circle Created with python_avatars nick beaman says:

    So I would take this video to the dealer and show how easy it was to fix it and demand my money back for the parts replaced. Got to love swapanostics.

  13. Avataaar/Circle Created with python_avatars Mike Cunningham says:

    You are Da Bomb!

  14. Avataaar/Circle Created with python_avatars chris allen says:

    You have all the great qualities of a great mechanic. Good troubleshooting skills mixed tons of experience and common sense. I enjoy watching you figure stuff out and talk about random bs as you go

  15. Avataaar/Circle Created with python_avatars charlie brown says:

    You see thats the beauty of having common sense and being in the business as long as you have…as always good video and keep up the good work!!!!

  16. Avataaar/Circle Created with python_avatars Michael O says:

    Don't overlook visual inspection, pure GOLD! 😂

  17. Avataaar/Circle Created with python_avatars Mario Tejada says:

    I had a similar problem with a 09 SantaFe. Had a cam/crank dtc. No one could figure it out. All it took me was a mirror and led light to find out it had rodante damage. That turned into a 10hr cash job 🙂 extended warranty paid for a new wiring harness. Took me 20mins to diagnose and 4hrs to install the new harness.

    I also had a kia Sorento with a crank no start and a immobilizer dtc. That one kicked my ass and tech line for about 2days. Turns out the coil packs were toasting the pcm. The vehicle came to us from a bodyshop. I could’ve sworn it was a damaged cable somewhere but nop.

    nice video.

    Good Catch, Making customers happy and being impressed with your work ethic, will give you a lot of repeat business and word of mouth advertising is nearly priceless.

    Eric. In my dreams I could not do what you do.
    At any rate, I am inspired!
    You are a modest man. You don't even know how skilled you are. Diagnostics, visuals, knowledge, patience and good humor.

    GREAT thanks.

    today I learned the term "tesa tape". Always picking up little tidbits in every video. Thanks.

  22. Avataaar/Circle Created with python_avatars Todd Kelley says:

    Another good trouble shooting video! Eric reminds me of an old wise hvac instructor I was lucky enough to study under many years ago, he would say " sometimes you have to think think and think" please keep the good stuff coming Mr O.

    You sir, are why I love YouTube! I was faced with a big multifunction copier yesterday that threw codes that weren’t in the book. Story short, the paper deck can throw codes the service documentation didn’t have. Fixed it right with no parts—visual inspection revealed a sprag roller in the wrong place, move it, it cleared the jam code and all was well. “The POWER of visual inspection” was going through my head while digging through the beast.

    Best part? Customer admitted after it had been moved and quit working after it was moved—movers apparently tried to use the slot in the bypass assembly as a handle, which is how the roller got moved. Eric O truism #2: “there’s always more to the story.” 🙃

    It’s really sad that dealership mechanics these days aren’t capable of finding a broken wire. Make she wonder what the world is coming too. This guy should go get his money back for the unnecessary alternator replacement they sold him.

  25. Avataaar/Circle Created with python_avatars The Overclocker says:

    Damn wth happen to that wire look like it pulled through oil factory. Id get some electronic cleaner clean it up and shrink tube it . Ship it. Dealers are trolls.

  26. Avataaar/Circle Created with python_avatars Donnie Robertson says:

    Great job again my friend A+

  27. Avataaar/Circle Created with python_avatars Jimmy Turner says:

    Hope he takes this video back to dealerships and shows it to them and insists they give him back his money back cuz you have incompetent parts changers that all they know how to do is throw darts at it.

  28. Avataaar/Circle Created with python_avatars Billy Yoder says:

    Thank you Eric. Good job.

  29. Avataaar/Circle Created with python_avatars Lynn Wray Dillard says:

    Don’t you know that dude from PA will get a thrill showing off this YouTube vid to his buddies. Even better would be seeing his Ford dealer techs watch this vid. Watch and learn from the master.

  30. Avataaar/Circle Created with python_avatars Lynn Wray Dillard says:

    Your amazing. With every SMA vid I watch, I think “it would be worth it to haul my 06 Pilot from north Alabama to NY so you could do your magic.” But it running great today, maybe tomorrow. You do great work.

    more reasons why I will never buy a ford. Who runs a wire over the top of a rotating object.

  32. Avataaar/Circle Created with python_avatars Old Time Farm Boy says:

    In the 70's I had a Ford stake bed truck that kept cooking the batteries. We went through several batteries before we could corner one of the drivers and question him. Found out that they had no problem during the day but smelled rotten eggs at night. In other words, when they had the lights on was when the problem started.

    Finally got the truck back into the shop and recreated the circumstance where the battery started cooking.

    At that time, Ford used external alternator regulators that were usually mounted on the frame next to the radiator. What we found was that the ground strap between the engine and the cab was loose and corroded. The battery grounded to the engine and the rest of the truck grounded through the cab and the ground strap between the cab and the engine.

    So whenever the lights were turned on, they were grounding out through the alternator regulator which caused it to stop grounding through the frame and made it think the voltage from the alternator was too low.

    Result, the regulator was increasing the voltage to a level our test gauges could not read (100+ volts) and was sending that voltage into the battery.

    Removed the cab ground strap, cleaned everything off, put it back together nice and tight with dielectric grease to prevent corrosion. Problem solved.

    good fix, congrats

  35. Avataaar/Circle Created with python_avatars pyro323 says:

    Gotta love it when even the dealerships fire the old parts cannon at your car. Eric uses common sense and solves the problem.

  36. Avataaar/Circle Created with python_avatars bill chapel says:

    The big Name brand shops rely to much on their technology tools, they just don't have the old school mentality, they just start chucking parts at the problem at the customers expense.

    Wish it was you teaching all the future techs!
