    I'm 68 years old. I've been renting since I was 15. Got my mechanic's license when I was 22. I was a long time ago. I listened to a lot of these videos as a refresher and find them interesting. Many of them are just so well done, but I have to say I wish it would leave the darned music out of them. I think if you're serious about the content, it's completely unnecessary. Anyway, this is another very well done one I think. Appreciate them posting it

I spent all day today trying to diagnose a Bobcat tracked skid loader that is having electrical gremlins and it won’t power up the display panel. I traced the problem down to a faulty control/display module. Its always a little stressful calling bad modules when they cost $1500 dollars to replace! But based on everything I seen its gotta be the panel.

One question, what if the resistance between high and low speed can becomes crazy moving up to 500 ohms and decending to 50 ohms?

    Hello thanks for a great tutorial. I try to resolve electrical issue on my Passat b6 BMP 2008 DSG car, for a week with no success. Yesterday I take multimeter with me and try to measure 6pin and 14pin from OBD. The result for voltage between 6th pin and ground was 2.5v, pin 14 and ground was 2.5v. I think that not have communication, but this is all of the time. Another test was for resilient. I try 200ohm between pin 6 and pin 14. Result was between 68.1 in most time and 71. I try to remove all positive cables from fuse box near engine and battery, nothing happened with resilient. After that I remove abs plug and again 68.1ohm. Finally I unplug every one cable in engine section and spray it with contact spray, I change fuse box in engine section, change gateway module, after all situation is same. I remember that before mass problem with multiple MILs and going in service mode I have a couple of day, maybe a week MIL alerts for steering.
    I change battery with new one and maintain alternator.
    P.S All of scannings with diagnostic tools say that I have a impulsible signals, lost communication with different modules and etc.
    Please give me advise what to do, because I was in two different car services and nothing happned.

    Agree best simplified by far and heading back to the garage to troubleshoot.
    I'm working on a project to customize 1996 with a 2017 canbus. I'll be removing some of the canbus devices, but not sure how to get around a device that won't be used anymore. Like the electronic parking brake. But still, I will keep using the manual ebrake. Do I need to loop high w/high etc or how would I terminate the end as in the device did not exist. I will edit it out of the programming as well. Thanks
