How to find a short to ground (blown fuse)

[@UCs6ktlulE5BEeb3vBBOu6DQ]

Bought a used Solus Pro and Vantage Pro and its a lot of fun finding troubles on cars. Last week I found a faulty IPR valve on a Ford diesel. Solus showed the pressure of the oil being not regulated and at the same time the Vantage showed the IPR being feeded the required voltage AND with the Amp clamp I could see the wattage over time. No more guess work.

[@douglasthompson2740]

Daniel Lelievre Sounds sweet. Not much of a used market in Alaska. I might have to research the $200 and less models.

[@00jake00]

One thing I like using when it comes to a fuse popping issue is to pull the fuse out and run your test light inline in replacement of your fuse. If it's a short to ground the test light will light when the wire is grounded. This won't work with every situation but it helps keep ya from going through handfuls of fuses during diagnostic.

[@jeremytrivette3894]

I tried this and blew my tester lol

[@AlexOsbaldo]

That doesn't quite make sense. If you place your light, inline in place of the fuse, you would just be completing the circuit, of course it would light.

I try to ask as much as possible. Always an issue with work done in the past when not done properly lol; a lot of times though, the owner just bought the car and have no history of it lol. Same goes with buying broken cars and reselling them, unless the owner is the one selling it, then you can squeeze as much info as possible prior to making the purchase and get an idea on what you are about to get your hands on.

[@EtienneNavaar]

I'm not very optimistic when it comes to mechanics. I think most would have put in a new fuse and sent you down the road. I have to say you really showed a lot of knowledge and skill to track down this short. Kudos to you Dan and thanks for sharing your knowledge with us.

I agree with Daniel, can't believe how much I'm learning, and have been doing it most of my life. Today, you have to know electronics better, or your out of the game !

[@carefulobserver6102]

Good video. I like your tip on carefully following the harness and pushing on it without moving it to find the short.

[@thedailylogger1045]

Great video. Wiring issues can be so time consuming and difficult to identify. Terrific job of explaining your techniques and the important tips, look at the diagram first, look at the potential problem carefully first, look at the OEM installation carefully before making a repair and repair it back to how it was. Good job, thanks!

It's amazing the genius it took to design such an amazing circuit powering the alternator.

Great follow through with the original problem, Paul! The reward of discovering the root cause makes it all worthwhile, eh 👍🏼👏🏼

[@ScannerDanner]

Absolutely

[@abcdefgh9138]

Watching this video paid off big time for me last week! Had a Honda popping the PGM-FI main relay fuse, power distribution diagram says it feeds about ten circuits, one of which is a heated O2... The logic of 'check the wires that are most likely to be damaged first' was perfect. Found the short in minutes, instead of hours.

[@ScannerDanner]

Sweet! Thanks for being part of this with me.

[@hopper1]

Butt connectors not shrunk, chafing wires, bad harness tie up, "universal" parts...Just goes to show that when someone chooses the "cheap" path, they get what they pay for. Whenever I find crap "repairs" like that O2 sensor are the cause of a problem, a string of expletives usually flows from my mouth followed by a feeling of satisfaction that the problem has been found. I enjoyed the video. Even as a salty, old wrench turner I learned something new.

[@billrimmer5596]

I have watched these two videos a few times. They r not new. But this case study is invaluable. This is Paul at his best!! And yes I have Scanner Danner Premium. Way better than C.S.I

[@ScannerDanner]

Thanks Bill!

[@angryfurbie]

Watching your videos is like apprenticing for a great drivability tech.

[@Pontisteve]

Improper O2 sensor replacement/aftermarket junk leads to alternator not charging. Brilliant my friend. Today you have taught me the value of not rushing to wiggle test, and also that alternator lights can trigger the alternator to turn on. I thought they were all either PCM controlled or completely standalone.

[@brentowen9480]

Great tips, and I really appreciate the extra info on Mitchell's diagrams. We have Mitchell's, the vantage, the vantage pro, and the verus at work, so pretty similar setup to what you use. I've never taken the time to fully read thru the "using mitchell's diagrams" tab. I will now that you've shown that there is good information to be learned there. Thanks.

[@JamesMossR33]

A great video as always Paul, thanks. I can't believe anyone (let alone anyone in the trade) would do a repair like that, I would NEVER run bare wires through open holes...manufacturers don't put stuff in for the heck of it. I do this stuff as a hobby and learnt a long time ago that you're asking for trouble using electrical tape not heatshrink or twisting wires together instead of soldering. Your diagnostic skills are awesome, an automotive Sherlock Holmes!

[@wiggitywhitefox]

Have you not ripped apart a OEM harness? 80’s-90’s engineers commonly used electrical tape and commonly used copper clamps and literally triple wrapped wires together in a main harness with a copper holder that are known to corrode 1 wire to 2-4 wires lol it’s OEM engineer harness work I see this in a lot and replace this on a lot.

another great vid mr danner, im totaly with you. i do not like to fit the non standard o2 sensors for that reason.

[@LynxStarAuto]

Prioritizing variables. This is definitely key to efficient diagnosis. The students at Paul's school are lucky. I would say the biggest problem techs have is proper diagnosis. This case study though can throw you off, because since this car is a convertible, interior components can also be causing intermittent issues due to water leaks. Still I probably would have gone O2 first...

It is a cam built into a pair of glasses that you wear on your face. It is coming out next year. Maybe it could help. I don't have any financial interest in Google Glass. So I'm not promoting it. Maybe it would help you in taking video of your repairs.

Paul, I enjoy learning about trouble shooting electrical problems from your videos. Please don't make another video with another mechanic or instructor.

My Chevelle shakes all over the place. Anywhere there’s potential for wire to rub a metal edge ill use like 3/8 transmission hose slit and slide over the metal edge or use pieces of old radiator hose as insulators. Over wires in short lengths as needed too. Bill hole drill a small hole and zip tie to hold slit hose on edge of a big hole😊

What kind of mechanic would use a universal O2 sensor and leave such a crap wiring mess... To not return the wiring back to near original configuration is just asking for problems and expensive repairs. Great video for first investigating probable wiring shorts. Only thing I would have done differently is ask what was worked on before, prior to the most current I electrical issue. More times then not it will lead you to the origin of the current issue.

A little bit bummed that Danner didn't show his fix for this wire wise, especially since you really can't go overboard on dealing wires and insulation in such a harsh area of the vehicle, especially if you live and drive in an area where they put the salt on the roads. This harness here is indeed a ticking time bomb for such an environment just waiting to blow up completely. Regardless a good and methodical video.

Hey Danner, How Are you ? Your videos have helped me a lot and I have learned from them too. But I wanted your opinion and help to help me identify an error code U0101 in my 2012 Kia sorento LX. The car was running normally until I stopped for dinner and after trying to start the car, I could not start the car. Bad battery with corrosion. I tried to clean the battery and the + terminal broke in my hand. I changed the battery and the connector and when trying to turn on the car I saw the lights on the panel. I went straight to the Kia dealer to see the problem and realized that I could not move from Park to Drive. I used the screw driver and put it on the drive and the dealer they wanted me to pay $ 1500 for a new ECU. Would you have any idea how I could be sure that this ECU is actually Damaged. Seeing this video I thought it could be the CAN communication Hight wire from the ECU to the TCM. Any idea? - I will check the Meter Fuse just like you did here, but all fuses/relays looks good.
