    Ok so my 2016 Santa Fe keeps blowing multiple fuses like the fuel gage and speedometer. When this happens it always won't come out of park. I'm able to get it going by sticking the key into the shiftlock override but this keeps happening? Any thoughts? Thank you!

    Do you still do or have time to do mobile diagnostics

    I’ve used a Telcom tool we call a breakdown. It works perfectly when you have a solid short between two primary wire conductors. If your second conductor is the chassis (short to ground) it doesn’t work. The breakdown tool welds the short and then the tone will only travel from the tool to the short and not beyond the short. This is used in cables with hundreds of conductors and is awesome when your affected circuit is miles long. You must remove the “component” at the far end (the customer house In Telcom) then you GIVE HER THE BEANS!!! Weld that short with high voltage and amperage, estimate the distance in ohms to feet, and follow your pickup coil right to it. This would be risky in an automotive application. But hey follow the smoke 😂 I feel like your power-probe tool may have similar limitations and maybe works well if you can isolate two individual wires that are solidly shorted together (less than 10ohms) and connect the two leads to them. I do not recommend applying the weld it together part on a car though 😂

    Rather than you feeling embarrased about filming your fault tracing you should invite the other guys to follow along. That way they may learn other tecniques which they can employ at a later date to actually solve the problem. Bit two faced if they smile at your filming then ask you to help with their problem.

    I had a Datsun that did that back in the 90s I paid 50 bucks for it never found the short
    I put a headlight in place of the fuse and drove it about 50k miles before it went to the bone yard
    The old fuse would blow about once of twice a day the guy I got it from had it to 2 shops they couldn’t find it because it wouldn’t blow there

    So even when it’s not shorted all the time light bulb trick does work

  30. Avataaar/Circle Created with python_avatars residentevilchris06 says:

    Ah yes, the classic reach around causes the breaker to blow. xD

  31. Avataaar/Circle Created with python_avatars J F says:

    Can a bad fuel pump keep blowing a fuse ?

    Where do you find all of your diagrams and pictures; I am trying to locate the crank sensor and camshaft sensor for a 2007 Hyundai Santa Fe 2.7L; thanks!

  39. Avataaar/Circle Created with python_avatars Mike Mardis says:

    Maybe it doesn’t short due to the breaker. You have said in the past that you don’t trust those breakers.

  40. Avataaar/Circle Created with python_avatars gunsaway1 says:

    Throw a 30 amp in it! Southern style. Lol

  41. Avataaar/Circle Created with python_avatars Vincent Hall says:

    HI
    You are pretty good. i have an issue with my 2002 hyundai santa fe 2.7l, it is sparking at the harmonic balance. the engine has lost most of it power. not firing on two cylinder from the same coil. changed the coil pack . same problem.
    no i dont live in the US. any ideas, some tech say the harmonic balance is bad??????????

  42. Avataaar/Circle Created with python_avatars Spear 327 says:

    If I can do it you can do it, BS. Kinda like saying if Michael Jordan can do it you can do it .

  43. Avataaar/Circle Created with python_avatars chris d says:

    So I neeeeeed help lol, so Hyundai decided they were going to put the ac clutch in the big ecu block and I dont want to mess with it and in order for them to even look at it is gonna be 175 bucks and I really dont want to pay for that and I'm really pissed cuz it just broke on me in the beginning of the summer time😂( my bad luck at its finest). Do you think it's an ac fuse? I noticed the ac isnt blowing humid sticky air when the ac switch is turned on. The only reason I know about that is because I had an 03 lancer and the clutch coils were bad and I had to manually enguage it with a bar but this time my hyundai is a free spinning one but it's not humid when I switch it on… is it the fuse? The clutch? The ac wire? And how would I go about the fuse if it's in the ecu?

  44. Avataaar/Circle Created with python_avatars Dominique Dees says:

    Im not sure if you will see this comment but i need some help, the ECU-C fuse keeps blowing on my 2010 kia rio
