    I see this kind of wiring damage quite often on accident vehicles. Usually shops are pretty good about spotting busted harnesses, but I get quite a few calls saying "The harness looks good, we went over it several times," only to find this kind of internal damage, and you absolutely can feel it if you run your fingers over it!

  • @timowallin8020
    @timowallin8020 Před 8 hodinami

    Hmm.... to me (in FIN market area) it's 90% not seen by "naked eye" when the wire in side has green infection... ...the other then is when winter(studs) /summer tyres get swiched the abs wire get binced betwean the wheel and the shock and cut was made. But then again your lucky if you find active aftermarket ABS-sensor that works, on any car. ...Specially if they are rounded with garbage bag for you that says some thing like "if opened no return!" ...that means "DWD" Dead When D...! one car had ~10 different aftermarket makers for abs sensors for the car and the cheapest without back worked funny thing was some of them showed speed on scan pid!!! but the dtc come back secend you put power on! and dvom showed why. it tested differently then the original! PS.on active switch polarity of the leads when testing! some of them has diode or something as they shold be OL other way and like 1.6Kohm other... ...im at 2:34 so sorry if you already talk this on video. EDIT: 5:52 remember the suspension moves. So the wire can need to bee longer when wheel turned (all the way) and its bottoms up with bump on road! I find Mercedes VAN ABS sensor that run from back to front...(Yes ask customer first! dos he/she want you to run the cabel and strip the van or can you cut and keep the extra wire first!!!! EDIT2: 7:00 Yes you can! .. atlest every one that i have needed to test! Yes! one way can be OL switch the leads ON THE METER SIDE! and Heureca. PS usually the 4 sensors have same walue but at lest the same axel has the same resistans when all is good ! EDIT3: 8:00 Again OL only on one way! Both ways is bad sensor! At least everytime in here and YES some times only ORIGINAL WORKS AS Covid copied SHIT to aftermarket sales!!!! EDIT4: 11:17 Then eather you have weak battery on your DVOM or you dint think to test it other way around! the same gos with injectors thes days so come on!!!! EDIT5: 14:40 So, the how you explain this? ..They arent OL anymore? I expect the active sensor has protection for wrong way voltage/current or some a mount and thats why its "OL" for one way and go for other... EDIT6: So is it OL both ways or not? if it is thenthats the first for me But then again i hardly work on USA cars in Finland so most of them are EU and man my brean.... Sorry my bad English! and hay just now i noticed that i see this on YT and not on sd.own site so sorry as i pay it i wil be back after summer vacation.. you can count on that! ;)

    That clip on the aftermarket hubs sucks. I always remove the factory clip and re-use it. I did a repair on a wheel speed sensor on a Lexus last year. The sensor was just under $500 with shipping, so I opted for a wire repair instead. That was one happy customer.

      I personally think a good shrink wrap (the one with the internal glue) is okay. Especially when it's on a stretch that's secured to the chassis. On the unsecured part that flexes as the wheel moves, not so much.

    We once had a broken wire to find - visual showed nothing so we split the wire down until we got down to a 2 foot segment passing the rad. fan (the most likely place obv.) No visible damage - no 'lump' where corrosion was insside either - eventually we found where it was broken but there was NO corrosion and NO evidence outside of the insulation - it had just snapped inside the insulation!! Factory defect perhaps - maybe previously pinched or caught on something - weird-as-hell thing to find tho...

    I had a Fiat Stilo with naturally aspirated 1.4 that claimed 90hp. It was a nightmare to drive with AC on. And I really mean a hell of a nightmare. Each time the compressor kicked in I had to give it full gas to even do anything. Now I have another Stilo, with a 1.9 JTD 115hp turbodiesel. Same car, same weight. I almost don't feel the power going down when that compressor is on. Maybe if I upshift a bit too soon, and the rpm gets below 1500, it doesn't pull as hard until the turbocharger spools up. But that's it. 90hp vs 115hp - it doesn't seem much. But as far as it goes for the torque, it's 128Nm vs 230Nm. And that makes a difference.

  • @danthurman9076
    @danthurman9076 Před 22 hodinami

    There should be a sight glass in the discharge line from the compressor to the evaporator to see what the system charge is. That system doesn't have a TXV,it has a cap tube with a meetering office. If you are using 134A it needs to be added as liquid because 134A is a blend of 2 refrigerants. Take a reclaim tank pumped down to 28 inches of manifold vacuum and pull out the 2.5 pounds of refrigerant. If the receiver dryer wasn't changed, that is the first place to check for a restriction, touch it for temp change
