The Trainer #23: How To Repair Wiring and Wiring Connectors

Автокөліктер мен көлік құралдары

#wiringrepair #buttconnectors #wiringsplice #connectorrepair
Troubleshooting and repairing electrical problems is becoming a daily task for professional technicians. Often, the cause of the fault is a damaged connector or wiring harness. Its proper repair is critical to the correct operation of the electrical circuit it is a part of. Incorrect repair methods could actually create additional faults; faults that may or may not be readily apparent.
In the November 2012 edition of the Trainer, we take a look at common mistakes made that lead to circuit issues and how to prevent them. We'll also share some specific repair techniques you can use to correct bad connections and damaged wiring. Click this link to subscribe to Motor Age! bit.ly/MA_YT_freesub

    Great tips. I'll be installing a new harness on my interior fan control of my Dakota pickup truck this weekend. Good to know about this sealing and weatherproofing ahead of time, just in case I need it.

    Thank you Pete I enjoy watching your videos I've been learning a lot I did manage to wire my fuel injection to my injectors but I use the wrong wire so I'm redoing them I was remembering about resistance and current and I needed the right size proper wire thank you appreciate your videos and thank you very much very grateful for all the knowledge you have been sharing

    Voltage on the car will remain relatively stable. Resistance changes due to corrosion, loose connectors and other unwanted "thieves" in the circuit path. That does, indeed, cause current flow to drop impacting the ability of the circuit to work as designed.

    Pretty good video Pete! The only thing that I like to mention is that at 15:10, you show crimping a terminal which has dual u-shaped sections. The front section gets crimped around the wire and rear section around the insulation. There are special crimp tools for just about every terminal, but they're expensive. As for the generic crimping tool, I just use it for cutting screws. From an electrical engineer who works for the largest connector and terminal manufacturer in the world. Thanks Pete!

    You should have stripped the wire to show proper crimp on open barrel terminal (some people will not hear what you said and just copy what you do). Also solder is not always a good choice because it will travel up there wire making it stiff and causing a potential break from vibration. That is why manufacturers have developed connectors with strain relief and wires that are flexible to take the vibration. A "properly" crimped connection is every bit as good as a soldered connection. I used to solder all my connections until I understood this concept.

    I feel your frustration! The first thing to do is verify that this is your problem. You can do this easily by measuring the voltage drop across the circuit. (See our channel for several videos on this method of testing). Cleaning/repair depends on the damage. If it's just oil-soaked, a good electrical contact cleaner may do the trick. Stabilant 22 is an excellent cleaner, but expensive so use it sparingly. Removal is dependent on the connector design, that varies quite a bit.

    Good Info. But got to remember to put shrink wrap and other dodads that work with or instead on the shrink wrap. Other wise you need to cut the connection again and put shrink wrap where it will do the most good.

    As an Aviation electronics Tech for C130 Hercules aircraft this method (piercing)is highly forbidden, due to the corrosion factor. Back probing is by Navy/ Mil standards recommended.Servicing aircraft at sea is more susceptible to corrosion. What the automotive industry needs is have "break open box" to access the hard to reach circuits like we have in the aviation industry. Tx for the vid it is very informative.Heat shrink & solder type are what the Military recommends.

    Pete, my problem is a step earlier. this removing the connector from the circuit device itself. I've encountered a number of different connector designs, each with its own release method. The current problem is a 14 pin connector connected to an A/C-coolant system control circuit in an 05 Golf. The shop manual doesn't show how. Also what is the source of the 'in line' wire stripper? I've been looking for one of those for a long time. Great detail! New (to me) info on more sophisticated connector

  • @niole2113

    At 9:19, I absolutely can NOT see how to insert the release tool, does it go on the sides? (*edit-- I just watched this again, and again, and notice you say the tool goes in the notch at 3&6 o'clock. is that right? Or it the 9 & 3 o'clock positions? I can't see it! ) I like the rest so far, very much. Great info on using the piercing probe and especially sealing the holes-- how many techs actually seal them? Not too many in my experience... Thanks so much for this video. ... also at 20:19, you mention to make sure to have the Crimper properly oriented... but I can't see what you are doing and I don't really know HOW to properly Orient the crimper. In general, does the bump/protrusion of the crimper go on the middle part of the crimp fitting, and the ends of the crimp into the concave area of the crimp tool? Thanks again

    At 9:18 on this video, NO, I cannot see! I get the gist of it. I've been at a loss to understand how to take apart my Dodge Caravan electrical connectors. A bad oil leak from the valve cover gaskets has saturated the transmission wiring, and motor mount also looks degraded, and now the trans limping. I suspect wiring problem. It needs a good cleaning, possibly replacement wiring connectors. As a mere mortal I need all the help I can get on this. How do I clean electrical components? Thx, Nicole

    Just like they say not to use solid wire, do not solder connections on automotive wire. Viration will break soldered connections. Use open barrel splices and proper open barrel terminals.

    Need to do a better job , perhaps enlist extra help on the camera filming end or even use a go pro , so that we can actually see what you're doing. As someone with no experience trying hard to learn, it's extremely frustrating when I can't see what, how, and where your plugging something I can just see your hand. That's not helpful at all. Otherwise your videos would be helpful and informative.

    This is a bad video. Every time the instructor tries to show something he immediately takes the item out of frame or gets his hands in the view of the object he's trying to show, or doesn't turn the object around to show the point he's trying to make. Or the camera man is terrible at his job. One of the two.
