How to find broken wires

How to locate a break in a wire harness

[@1234567896783]

That was the smartest continuity video I’ve ever saw thank you

[@plowhand5591]

Guys like this are getting harder and harder to find. Thanks for the enlightenment! 👍🇱🇷👏

[@richardhill2379]

Running 6 years now and you are still teaching us, awsome tip, will be doing this on my eng harness this weekend. Thank you sir !!

[@angelinas.6695]

Absolutely a great tip for finding the break in a wire. Saves a ton of time and frustration. I don't know why I didn't think of doing this on my own. It's so simple! Thanks for sharing.

[@TorQue_WrenCh]

Since that tips is nice,and the voice who teaching is honest in giving his skill,i gave this video a like,and thank you to the man..

U good

[@Spitfireseven]

That was a great, practical tip. You have the best meter, Fluke. That thumbnail tip was fabulous.

[@kenzpenz]

I am 78 years old and have worked on a lot of vehicles, but honestly that is the first time I have seen that tip with the thumb nail. Great tip indeed, yes you can teach an old dog new tricks. Just curious, what would cause those wires to break like that, it is stranded wire. I can see solid wires breaking but then again you don't see solid wires in vehicles. Thanks for sharing....Ken

[@Rusty411]

it is the wire they use now in everything it as weak as a coat hanger if it bend back and forth or even vibration it breaks clean it's stranded 18 gauge wire it's all low voltage 5 volt so they use small wire cheap wire on everything

[@Rusty411]

thanks for watching sir

[@mohabiraq1]

Vibration

[@Spitfireseven]

One good overstressed yank will do it. The plastic cover stretched, the wire won't! Haha!

[@swee78]

@@Rusty411 absolutely, vibration even on a small 3 cylinder engine (along with poor routing without enough strain relief) and the wires will just fatigue break in as little as 15K miles.

[@dporrasxtremeLS3]

This is one of the best automotive videos I have seen on You tube! I am having an electrical issue with my truck now, this is how I found your video. A thousand thank yous!!!

[@jimmyjimmy951]

Great bush mechanic tip. A solder joint would have been the icing on the cake but again great trick for an old dog like me. Keep up the great work. 👍🇦🇺

[@raylouis6231]

Thanks Rusty , for sharing your knowledge . especially the finger nail tip . although whole video was spot on. great for helping others save on the cost of those new expensive cables !

[@DEEJAY7950]

Probably the best informative video in real life action, thank you for sharing this!

[@rodneybrowning8358]

i know you say its basics. but its good to see the little tricks from the guys in the field figuring stuff out. this is why i go to you tube, to get the other guys idea and maybe save time and learn some simple stuff. thanks for the thumb nail trick. been chasing a dead wire on my boat trailer. was about to just install a new harness. but now armed with a good way. i can hopefully save some money.

[@ryanmoore2961]

Just came across this video for the first time, really helpful tip, as I am currently diagnosing some possible wiring harness failures and can't pinpoint the break based off of looks alone. Thank you for posting!

[@ogebogi]

Excellent tip. Thanks for taking the time to make this.

[@soopavillian1987]

Good video Rusty, this testing is also useful when changing wiring harnesses when the wiring color doesn't match both sides of the plug.

[@ryanm4738]

A way more simple way of explaining it than any other video I’ve watched and makes a lot more sense too

[@jasonmesser3042]

Awesome trick using thumb nail to locate the break in the wire and way cheaper than one of those annoying devices that beeped until it locates the break. Thank you for this gem . I've watched so many videos where they over explain everything and I end up more confused than I was before their video.

[@samuellindstrom2137]

Thats a really good trick! I've never thougt of running my nail across the wire. Thanks alot, keep up the good work man ☺

[@AndTodaysProjectIs]

I don't even know why I continued to watch this video to get to the thumbnail part but damn I am glad that I did. I thought it was just a video on basic continuity but that thumbnail trick is some seriously valuable stuff! Thank you very much for posting that

[@annfarmer9704]

True working man's hands... Practical and concise tip, thank you, I will be implementing this rewiring my rv.

[@TIMMIELUND]

That video is a classic learned a lot today.

[@jake-mv5oi]

I like that thumbnail trick. I had a no crank problem with my XJ after I bought it and couldn't find the problem to save my life. Finally bought a FSM and traced it down to the wire between the clutch safety switch and the starter relay. I never did find the break. Was lazy and spliced in a new wire next to the connectors and ran it through the firewall... Ain't pretty, but it still works.

[@Rusty411]

sometimes that's what you have to do man if it works it works thanks for watching

[@jimgibson4760]

Great tip and well explained. Thanks for taking the time to do this.

[@emiliohuerta2658]

Rusty, Happy new Year God bless you Sir that was an awesome way to find those breaks in the wires and reading comments you also mentioned the cheap wires been used and vibration causes as well thank you so much for this information.

[@tropicalfish666]

Cheers mate, really helpful video. I’m trying to learn some of the basics 👍🏻

[@morganclark9535]

I like that trick with the thumb nail man I'm glad I watched this video now I'm about to start working on my dads old truck to fix the AC in it and we know its a wiring problem cause we changed out every thing so ill be sure to use that trick thanks man

[@johneric3886]

[@Aikidobear129]

It goes to show you that if you want to know something useful ask the man who's been doing it for years with practical experience.

[@daveoverbey2032]

You are so right as it so many people think they know it all & don't know shit

[@tylercurtis441]

wow cool learned something to add to my tool box of "tricks" much love brother!!!!! cant wait to bust this one out on as buddy sometime hahaha i love to be the guy that fixes the problems

[@williambiggs2308]

Nailed it! Great video! Thank you!

[@Mister_Y]

So how do you check continuity where you don’t have access to one end? For example a wire got pulled while you were dropping the transmission and forgot to unplug a sensor but unsure if the wire was stretched to the point where it broke inside the jacket...

[@HewroPreez]

I will now forever know of this fingernail trick thanks to you. Excellent tip!

Good evening my friend and nice to meet you! It's an awesome video and i enjoyed watching it. My vehicle (2003 Dodge Caravan Se V6 3.3) is giving me a (P0201-Injector Circuit/Open Cylinder 1) code and i have a (2003 POWERTRAIN DIAGNOSTIC PROCEDURES book for town & country, caravan and voyager) that shows on page 88-89 test procedures to follow and apply. So far i have applied (test 1) and (test 2) and im on (test 3) now and im stuck on not being able to follow and apply it cause im not grasping and understanding it at all. This is test 3 Turn the ignition off. Disconnect the Fuel Injector harness connector. Remove the ASD Relay from the IPM. Turn the ignition on. Jumper the Fused B+ circuit and the ASD Relay Output circuit in the IPM. (This part im lost) Using a 12-volt test light connected to ground, probe the (K342) ASD Relay Output circuit. Does the test light illuminate brightly? Yes Go To 4 No Repair the open in the (K342) ASD Relay Output circuit. Perform POWERTRAIN VERIFICATION TEST VER-5. This is a video of me following and applying (test 2-@ and in that video it shows the pages in the book from page 88-89 and pages 312-314 for code (P0201-Injector Circuit/Open Cylinder 1). Are you able to please make a video showing me how to perform all of these test procedures so it can help me grasp and understand to where im able to apply the test procedures from all those pages?

[@IntheBlood67]

Rusty, you're an American hero.

[@kenwebster5053]

In my experience, broken wires are pretty rare, unless it's running between moving parts, like the taillight harness to the boot lid, or speakers & window winders in doors. Opening and closing these things flexes the wire till it eventually breaks from metal fatigue. It's more an older car problem IME. The more usual continuity issue is the connection between wire & plug contacts, or the contacts themselves. If it's a high current circuit, there may have been enough heat to distort the plastic plug right at the problem contacts. So, that can be a clue, but not always. The reason for the loss if continuity between wire & plug pin is generally corrosion/oxidation of the wire or the pin. Sometimes the pin may not have been crimped tightly so the air & moisture got to the metal building up oxides between the surfacers. You can often get something working again with some Deoxit contact spray, but it's not 100% over time. Deoxit is a good product that lasts longer (often a lot longer) than most any other contact cleaner, but it's really just sweeping the problem under the carpet. If you want to preserve the original plug routing, occasionally you may be able to repair the connection but taking the pins out crimping harder or soldering the wire to the pin. However, the more sure way is cut the old pins away and install a new connector that bypasses the original plug entirely. If you want to test continuity through a plug, you can either disconnect the plug either side of the suspect one & probe the exposed contacts, or you can push sewing pins through the wire insulation & conductor & use those to probe. Just remember to remove the pins after because shorts are not fun for anyone but spectators.
