Out of all the Videos on Dialectic Grease, this is the only one that is accurate. I have been using it for over 30 years and it always works. And NO it will not "insulate" a normally good connector, if it is metal to metal, the grease pushes out between the contacts and creates an air tight seal. This works on all automotive connections, and UHF connections at high voltage. Just make sure you don't lubricate a bad connector that then pushes back apart. I use wire ties on questionable connectors to make sure they stay plugged together. I have been rebuilding, and rewiring cars and off road vehicles since the seventies. I also rebuild vintage Amateur Radio Transmitters and equipment.
I agree with you 100%. I've used it for about the same length of time. I also have a boat and trailer and I cake on the grease on all electrical and batteries. And on other boats I work on. It's the only thing that saves electrical connections and adds longevity to them.
Thank you for this video, I've been seeing a lot of random and seemingly misguided information on dielectric grease which has made t difficult to discern whether I should apply it to my plug connectors. This explanation helped!
I agree with you 100%, I've been using it all over the electrical connections also pumping it in to the back of the electrical connections trying to get it everywhere that there is bare metal as well as plastic when the two terminals come together. just recently noticed people were saying that it's terrible to put it on the metal connections. from there I started looking for videos and information on why they would say that and they seem to be contradicting their souls. I don't see how you can stop moisture from getting in to electrical connections unless you cover the electrical connections. LOL I appreciate your time and information
I install security cameras. They use cat5/6 now with RJ45 network connectors. I used to see a lot of corrosion due to water damage for outdoor cameras before I started using dielectric grease. Since I started using it about 5 years ago I haven't seen a single outdoor network connection fail due to water damage since I've started using it.
Can you explain how do you apply it?...i am about to install a couple of poe cameras and i am thinking to use this for the first time. Thanks in advance.
I recently spliced headlight wires to add in an extra set of lights, and was considering what I could do aside from electrical tape that isn't fully sealing the soldered connection from oxidization. Great of you to have made this video! Thanks!
I looked this up specifically because I just had to fix the wiring harness of a yard tractor and was wondering if I should use this grease on all the connectors, you just convinced me and earned a sub
Always use dielectric grease to protect against corrosion. Spark plug boots and electrical connections. It has to be non-conductive, otherwise it would short out the adjacent pins on the connector.

Thanks for the great Information I just installed a new taillight on my motorcycle soldiered wires then used dielectric grease on soldier then covered with heat shrink tubing.
You're welcome. I'm glad you found it informative. I had a Cherokee Sport about that vintage. Loved that thing. Thinking about getting another one and fixing it up when my current Grand Cherokee is ready to be retired. Are you going with the stock power train or upgrading it?
Thank you so much for this. I have a high humidity house and my battery powered electronics get extremely corroded so often. I am constantly having to throw stuff away. I finally decided to spend some time researching how to prevent it. I finally found this but through another of your videos about Lithium grease vs silicone grease: Which to use? . This was after searching if silicone oil would prevent corrosion and still be able to use it on the battery connectors. Perhaps, if you have tags you can use, tag it with battery corrosion prevention. In the meantime, I will share the heck out of this to my damp climate friends in facebook.
So glad I was able to help! And that's great feedback about how you found the video. Thanks so much! I'll see what I can do about changing the search results. Thanks too for telling your friends. Much appreciated!
Good video Thank you. I've got a 40+ year old tube of Ox-Guard that is still the same as it was new. I've been watching sail boat videos to learn. Watched at least a hundred electrical installs/repairs. It only just hit me that no one was using dielectric grease, and there wasn't any on any of the connectors from the factory that they were working on. In boats it's common that a 5+ year old boat is rapidly becoming a maintenance/up keep nightmare, with numerous electrical problems. If water and oxygen can cause problems overtime, what do you think happens when you add salt? I've been messaging various experienced sailors about this. Dielectric grease is news to all of them. My tube of Ox-Guard has lasted so long because I was only using it on external wiring, especially garden lights and sprinkler systems. Now I think I'll use it on everything. The ground wires on my 70 year old house were all conducting about half the voltage - power strips can't work correctly. I figured the problem would have to be in the panel where all the wires come together. Nope. No clue where it's coming from - but it's clear it's caused by corrosion.(maybe a wire nut buried in a box somewhere) So for critical outlets (computers, GFIs, etc) I ran a new ground wire. (I rent or I'd rewire the whole place).
Wow, I would have assumed boat manufacturers would have put dielectric grease on all electrical connections. Amazing that they don't. Old house wiring can be a pain; you never know what was done.
Great video, thank you. I have an electric vehicle and was wondering if you could make a video regarding charge port preventative maintenance and other tips for EV owner’s? I am going to add a few drops to both my charger and port. Do you recommend doing this? Thank you
You can use dielectric grease on metal. But if you don't want something sticky, such as on a surface, there are waxes and other protectants that can be put on.
I liked the information and I subscribed, however, a piece of advice from the layman, an edifying example with a more explanatory video would be even better. More precisely, how and how much to put on the spark plugs, on the induction coil socket, on the light bulbs/signals. These small but filmed edifications would help a lot, especially for those like me, for example, who do not speak English well. Thanks!
Hmm, I never thought about it. The only concern I might have would be if the heat caused it to dry out and act more like glue. If it doesn't dry out, that'd be a great use case for it. I might try running an experiment and see how it works out. Peace.
Is there any difference if you use 3M Silicone Paste Dielectric Grease, Versachem 15339 Dielectric Connector Grease or Permatex 09980 Counterman's Choice Spark Plug Boot and Electrical Connector Dielectric Grease? Any preference of one of those to use on Spark Plugs and SP Boots? I know that some of them cure to the solid condition, some stay soft, so which one it is better to use? Thank you for the film.
Sorry, I don't know the differences between those specific brands. For spark plugs, you definitely do *_not_* want one that cures to a solid condition. That would make removing the plug wires in the future very difficult.
Great myth busting video. I was though unclear if it is wise to use dielectric grease on low voltage contact terminals eg various sensors/connectors. I was thinking it is a preventive maintanance to insulate those sensitive sensors against corrosion and oxidation. This may especially be helpful as we often clean engine with water and those sensors are of prime concern. Please share your thoughts. Much Love...
Yes, that's a perfect application for it. I've heard of people in the off-roading community going through their vehicle on a periodic basis and putting it on every electrical connector so their it stays reliable through the mud and water they run their vehicles through.
@@HouseOfHacks massive emphasis on not putting it directly onto contacts though need to make sure it's applied sparingly and only on the housing around the terminals though, otherwise you can get heaps of random electrical gremlins. But ye super common in off road vehicles every year or so Thanks a bunch for the video though, had ignition issues with my mk4 supra for the past 6 months and had a thought about the grease I threw on the plugs, aaannnnnddddd 30 minutes later your video handed me my answer finally lol
@House of Hacks -- Is it wise to put this dielectric grease on the connector points of BNC cables exposed outside to rain/humidity/moisture? My last BNC cable got corrosion/moisture damage. I need to replace the cable but want to put something on the connectors to prevent this problem in future. Is it okay to put this grease inside connector and then some silicon tape over entire area for overall protection?
House of Hacks - thanks for your reply. One last question on this, should I go out of my way to ensure the dielectric grease goes inside the small hole where the pin is inserted? Is it also okay to be generous in applying this grease?
I guess I could have done that, but this video was more about dielectric grease than it was about the repair, so I didn't really think about it. It wouldn't have been too exciting though, just the light coming on. :-) Cheers.
Hmm. I was sure I replied to your comment when you asked, but I don't see it now. Let me try again... I wouldn't suggest using this on potentiometers and faders. Adding a grease like this is going to attract dust and over time cause them to gum up. It's more likely they need a good cleaning with an electrical contact cleaner and some canned air.
Silicone grease and dialectic grease are similar but a little different. In general, dialectic grease will have a higher insulation factor. For low voltage applications, silicone grease is probably close enough to work. For higher voltage applications, I'd stick with dialectic grease.
@@HouseOfHacks thanks for the advice. I purchased some ignition leads recently for my car's spark plugs and I received a small packet with "silicone compound" written on it. The leads came with no instructions so I wasn't too sure what to do with it. I assumed it would be a form of diaelectric grease as I can't imagine what else it'd be for. (I'm new to servicing my own car).
Ah, right. Most plug wires I've seen come with dialectic grease. I'm not sure if is really silicone grease or a bad translation. In either case, I'd expect it to be OK.
Are you referring to a wire nut? That I'd just cut off with some wire cutters. If you're referring to something on a bus bar or something similar, I'd use some sort of penetrating oil. Regardless, make sure the power is off inside the panel.
@@HouseOfHacks yes, on a bus bar..main breaker of a Sub Panel. (See Above) I was hoping that you would suggest which brand of penetrating oil might be best. I want to make sure that when I power the sub panel back on that the penetrating oil that I use would not have an adverse effect, like arcing or some other problem, because of the high voltage. I want to make sure that I use the proper penetrating oil and not something that could be detrimental.
@@havenge32 Ah, right. Sorry, I'm not familiar with the pros and cons of the various brands of penetrating oil. If it were me, I'd use just enough to get the job done and make sure to clean it all up before putting things back together. I wouldn't worry too much about specific brands. But that's just me. If you're not comfortable with that, be sure to do your research (as it sounds like you're doing :-) ). Peace.
I understand using this on the inside of a spark plug boot for ease of removal but being that it has as stated, non-conductive properties, wouldn't there be a problem getting a spark plug tip coated with this?
Yeah, you wouldn't want to coat the tip, although it'd probably be burned off in short order inside the combustion chamber. But having it on the connector inside the boot actually helps. The grease will squeeze out of the way and allow metal-to-metal contact but isolate that contact from the atmosphere's oxygen and moisture to help keep it from corroding and oxidizing.
This is by far the best, clearest, and actually true explanation of dielectric or silicone grease. Could you do a video like this on white lithium grease. In the tube not the spray. I have read it provides the same dielectric properties???? I’m a missionary in Brasil and it’s tough finding the right things when you need. Also, can I use silicone grease or dielectric for brake caliper pins? Is it the same thing in a different tube? What’s the difference between dielectric and silicone grease?
Thanks for the kind words. I've not heard that lithium grease is a good dielectric, but all grease has some insulation properties. Dielectric grease is a type of silicone grease that is formulated to have extra insulation properties to help serve its intended purpose. Silicone greases and lithium greases are very different and shouldn't really be substituted for each other long term. It would probably be OK in temporary, emergency situations where it can be cleaned out and the proper one used at the soonest available time. Thanks for the question. It inspired a video that'll be released today or tomorrow. Peace.
Has “some insulation properties” you mean “insulation from air and water” ;) Did you notice how Your conductivity test took longer with the grease? I think it’s because there was no airgap to start the beep like the dry pins had to jump across (albeit a tiny airgap).
the only benefit I see is that it should help fend off corrosion. Other videos prove there is zero conductivity in dielectric grease as well as vasaline or "normal" grease. I think as long as you have something covering the metal against corrosion, there's no difference.
Yes, that's the primary benefit, and in damp environments, that's a significant benefit. It can also keep any plastic/rubber parts from getting stuck together and easier to remove.
Excellect video using correct scientific facts, instead of 'old wives tales'. I would like to point out that the reason it makes good contacts is, that when you slide proper fittings together, the grease is actually displaced, making good metal to metal contact. The gease surrounds the connection, protecting it from the elements. On the other hand, if you were to smear it onto flat mating contacts, like ring terminals or flat (Ford) battery posts, you don't get the scraping action and the dielectric can form an insulating barrier to good current flow. These are best connected dry and the dielectric added on the outside, for protection.
Don’t watch any other video on “dielectric grease” this is the only true video on TH-cam. Subscribe so his video gets higher on the search to replace false explanations of this “non conductor”
Changed out my PCM on my Jeep Cherokee year 2000 and it's still stalling at times or cutting out. Some people recommend using dielectric grease on the 3 terminals and then when I plug them back in also zip tie them in so they're even more secure. Any thoughts? Thanks.
It certainly wouldn't hurt putting grease and zip ties on them. Have you identified those connectors as being the problem? Can you wiggle them around and have it die while the engine is running? I had an intermittent problem on our Jeep. It turned out to be a wire in the engine's wiring harness where it went around a corner had worn through the insulation from rubbing and occasionally grounded out the ignition system. Our mechanic taped it up and rerouted the loom a bit so it wouldn't rub on the bracket.
Thanks so much for the quick comment. I did wiggle the connectors and it did not stall. Although, as you know, a vehicle sure bounces just enough to rattle the connections and potentially short. This is the second Jeep I've had to change out the PCM. First time it costs $1,500. This time I purchased a remanufactured for $170. Frustrating as heck. Can't complain much as the first Jeep went over 300k and this one has 245K. What makes it frustrating is mechanics seem confused. Since it happens intermittintly it's hard to diagnois. Today it's driving great. Crazy. Keeping my fingers crossed. Thanks again and any suggestions always welcomed.
It ended up being electric, but it was the cam shaft position sensor. I changed it out a week ago and not a problem since. Well, at least I have a new PCM.
Oh, interesting. I've never heard of that being an intermittent failure. All the cases I've heard of have been sudden and permanent. Glad you found the problem. Cheers.
Thanks for watching! Too much and it's just wasted Too little and it won't do it's job. If the amount put in the socket impacts conductivity, there's probably something mechanically wrong that needs to be addressed. Peace.
If it's an insulator, why did you gob it in your spark plug wire? WRONG! You SPARINGLY use it on the rubber insulator around the electronic component, not on the electronics to prevent arching.
Here's a comment from a guy who was a professional IBEW union marine-electrician journeyman-leadingman who pointed THIS out to me "Wonder why my power company guys don't use it.... Or try the logic from the other direction. If DG is so cheap and effective then why don't the OEM's use it? How deep does the conspiracy extend? I never had engineering instruction procedures to use DG." __________________
Don't know about the use in high and line voltage applications. For vehicle applications, the first time I ran into it was on a car where it'd been used at the factory. My guess is the reason it's not used more on vehicles is because the bean counters figure the the cost/benefit isn't high enough from their perspective.
I would not use it. It does not conduct electricity so if you coat wires with it you will cut down the current. You want Deoixit to cut down oxidation and has no effect on reducing electrical flow or increasing resistance. Take old N64, Atari Cartridges that no longer boot a game. Coat one with dielectric grease (it will fail) and spray another with DeoxIT D5S-6 Spray. The spray will bring it back to life, the grease will not. Alcohol did not ever work when Deoxit did on same contacts. Not sure why people use this connection killing grease except to keep water out but hurts the actual connection because its like tape, an insulator not a conductor.
haha. Yeah, I should have put it on. I do so little recording outside I didn't think about it until I was editing the video, by which time it was much too late. Peace.
Sorry, not quite sure what you're asking. Vaseline is different than dielectric grease and should not be interchanged. If that's not what you're asking, please be a little more descriptive in your question. Cheers.
@@HouseOfHacks Vaseline and Dielectric Grease Electrical Resistance in Wire Connectors th-cam.com/video/pC2HVoHWNLA/w-d-xo.html Excerpt from text right below video: ....Vaseline and dielectric grease are widely used in wire connectors of motorcycles and automobiles to keep the moisture out and prevent the connections from rusting and sticking. There are different opinions on how to use them and if one is better than other. The electrical resistance of each was tested and their effect in wire connectors resistance was explored. Both are NON conductors and slightly raised the resistance of connectors.....
@@tombouie Ah, I see. Vaseline is a petroleum based grease and may degrade some types of connectors. It's also highly flammable. I would not use it for electrical connections as 1) it may cause the fitting to get brittle and break and 2) if a high current causes it to heat up, it may catch fire.
@@HouseOfHacks Thks, really you should do a video on the compare. Vaseline on econnectors is a lot like sasquatch, ufos, ghosts, etc ; the myths just lives on, & on, & on, ..... , & on, & on, & oooonnnn

The leads came with no instructions so I wasn't too sure what to do with it. I assumed it would be a form of diaelectric grease as I can't imagine what else it'd be for. (I'm new to servicing my own car).
Ah, right. Most plug wires I've seen come with dialectic grease. I'm not sure if is really silicone grease or a bad translation. In either case, I'd expect it to be OK.
what would you suggest I use on an Electrical Lug Nut that is stuck? It is on a main breaker of a panel.
Are you referring to a wire nut? That I'd just cut off with some wire cutters. If you're referring to something on a bus bar or something similar, I'd use some sort of penetrating oil. Regardless, make sure the power is off inside the panel.
@@HouseOfHacks yes, on a bus bar..main breaker of a Sub Panel. (See Above) I was hoping that you would suggest which brand of penetrating oil might be best. I want to make sure that when I power the sub panel back on that the penetrating oil that I use would not have an adverse effect, like arcing or some other problem, because of the high voltage. I want to make sure that I use the proper penetrating oil and not something that could be detrimental.
@@havenge32 Ah, right. Sorry, I'm not familiar with the pros and cons of the various brands of penetrating oil. If it were me, I'd use just enough to get the job done and make sure to clean it all up before putting things back together. I wouldn't worry too much about specific brands. But that's just me. If you're not comfortable with that, be sure to do your research (as it sounds like you're doing :-) ). Peace.
@@havenge32 bus bar and nut copper or aluminum, size of breaker, voltage, single or 3-phase?
Also prevents my plugs from rusting 😁
Can you use silicone paste on spark plug boots?
Yes, that's a frequent place it's used.
House of Hacks Thanks
use a wind sock on your mic pls. but good info. thanks
Yes, a wind sock would have been a good thing to have. Thanks for watching.
Content starts at around the 1:00 minute mark.
I understand using this on the inside of a spark plug boot for ease of removal but being that it has as stated, non-conductive properties, wouldn't there be a problem getting a spark plug tip coated with this?
Yeah, you wouldn't want to coat the tip, although it'd probably be burned off in short order inside the combustion chamber. But having it on the connector inside the boot actually helps. The grease will squeeze out of the way and allow metal-to-metal contact but isolate that contact from the atmosphere's oxygen and moisture to help keep it from corroding and oxidizing.
Old school, Vaseline works great. especially on battery posts.
Yep, that works too.
Harley was really trynna off road on that curb lol
haha
JUST BOUGHT SOME OVER THE YEARS HAD FORGOTTEN
Sounds like it's time to put it to use. :-) Thanks for watching!
This is by far the best, clearest, and actually true explanation of dielectric or silicone grease.
Could you do a video like this on white lithium grease. In the tube not the spray. I have read it provides the same dielectric properties???? I’m a missionary in Brasil and it’s tough finding the right things when you need.
Also, can I use silicone grease or dielectric for brake caliper pins? Is it the same thing in a different tube?
What’s the difference between dielectric and silicone grease?
Thanks for the kind words.
I've not heard that lithium grease is a good dielectric, but all grease has some insulation properties.
Dielectric grease is a type of silicone grease that is formulated to have extra insulation properties to help serve its intended purpose.
Silicone greases and lithium greases are very different and shouldn't really be substituted for each other long term. It would probably be OK in temporary, emergency situations where it can be cleaned out and the proper one used at the soonest available time.
Thanks for the question. It inspired a video that'll be released today or tomorrow.
Peace.
Has “some insulation properties” you mean “insulation from air and water” ;)
Did you notice how Your conductivity test took longer with the grease? I think it’s because there was no airgap to start the beep like the dry pins had to jump across (albeit a tiny airgap).
By "some insulation properties" I meant "somewhat acts as an electrical insulator." ;-)
"I put that $h!t on everything!"
Well done!
the only benefit I see is that it should help fend off corrosion. Other videos prove there is zero conductivity in dielectric grease as well as vasaline or "normal" grease. I think as long as you have something covering the metal against corrosion, there's no difference.
Yes, that's the primary benefit, and in damp environments, that's a significant benefit. It can also keep any plastic/rubber parts from getting stuck together and easier to remove.
I think if we're splitting hairs, dielectric/silicone grease, is less damaging to rubber/plastic, than petroleum grease/Vaseline.
Excellect video using correct scientific facts, instead of 'old wives tales'. I would like to point out that the reason it makes good contacts is, that when you slide proper fittings together, the grease is actually displaced, making good metal to metal contact. The gease surrounds the connection, protecting it from the elements. On the other hand, if you were to smear it onto flat mating contacts, like ring terminals or flat (Ford) battery posts, you don't get the scraping action and the dielectric can form an insulating barrier to good current flow. These are best connected dry and the dielectric added on the outside, for protection.
Thanks for the clarification.
By not getting hard and staying greasy, it becomes a dust and dirt magnet!
good
Thanks for the encouragement and subscribing! Peace.
Don’t watch any other video on “dielectric grease” this is the only true video on TH-cam. Subscribe so his video gets higher on the search to replace false explanations of this “non conductor”
Thanks again!
thanks subd
You're welcome. Looking forward to seeing you around.
Changed out my PCM on my Jeep Cherokee year 2000 and it's still stalling at times or cutting out. Some people recommend using dielectric grease on the 3 terminals and then when I plug them back in also zip tie them in so they're even more secure. Any thoughts? Thanks.
It certainly wouldn't hurt putting grease and zip ties on them. Have you identified those connectors as being the problem? Can you wiggle them around and have it die while the engine is running? I had an intermittent problem on our Jeep. It turned out to be a wire in the engine's wiring harness where it went around a corner had worn through the insulation from rubbing and occasionally grounded out the ignition system. Our mechanic taped it up and rerouted the loom a bit so it wouldn't rub on the bracket.
Thanks so much for the quick comment. I did wiggle the connectors and it did not stall. Although, as you know, a vehicle sure bounces just enough to rattle the connections and potentially short. This is the second Jeep I've had to change out the PCM. First time it costs $1,500. This time I purchased a remanufactured for $170. Frustrating as heck. Can't complain much as the first Jeep went over 300k and this one has 245K. What makes it frustrating is mechanics seem confused. Since it happens intermittintly it's hard to diagnois. Today it's driving great. Crazy. Keeping my fingers crossed. Thanks again and any suggestions always welcomed.
You're welcome. Happy to help where I can. Intermittent electric problems are a pain. Good luck.
It ended up being electric, but it was the cam shaft position sensor. I changed it out a week ago and not a problem since. Well, at least I have a new PCM.
Oh, interesting. I've never heard of that being an intermittent failure. All the cases I've heard of have been sudden and permanent. Glad you found the problem. Cheers.
The key is you don't need to glob it on. If you do it could interfere with conductivity. It only takes a very small amount
Thanks for watching! Too much and it's just wasted Too little and it won't do it's job. If the amount put in the socket impacts conductivity, there's probably something mechanically wrong that needs to be addressed. Peace.
Can I use plane silicone grease?
Yes, silicone grease should be OK although it won't insulate as well. Have you seen my recent video? th-cam.com/video/JUkzNo5NG3g/w-d-xo.html
WHY NOT USE REGULAR GREASE ?????
Great question! Regular grease is petroleum based and may not be appropriate for all situations.
Can destroy rubber
If it's an insulator, why did you gob it in your spark plug wire?
WRONG!
You SPARINGLY use it on the rubber insulator around the electronic component, not on the electronics to prevent arching.
Here's a comment from a guy who was a professional IBEW union marine-electrician journeyman-leadingman who pointed THIS out to me
"Wonder why my power company guys don't use it.... Or try the logic from the other direction. If DG is so cheap and effective then why don't the OEM's use it? How deep does the conspiracy extend? I never had engineering instruction procedures to use DG."
__________________
Don't know about the use in high and line voltage applications.
For vehicle applications, the first time I ran into it was on a car where it'd been used at the factory. My guess is the reason it's not used more on vehicles is because the bean counters figure the the cost/benefit isn't high enough from their perspective.
I just wish you didn't read everything it seems like bad acting although the information is good.
Thanks for the feedback. I'm trying to get better. Cheers.
I would not use it. It does not conduct electricity so if you coat wires with it you will cut down the current. You want Deoixit to cut down oxidation and has no effect on reducing electrical flow or increasing resistance.
Take old N64, Atari Cartridges that no longer boot a game. Coat one with dielectric grease (it will fail) and spray another with DeoxIT D5S-6 Spray. The spray will bring it back to life, the grease will not. Alcohol did not ever work when Deoxit did on same contacts.
Not sure why people use this connection killing grease except to keep water out but hurts the actual connection because its like tape, an insulator not a conductor.

Next show: Audio in wind lessons! :)
Haha, yep. :-D
Heres a HACK for ya .., why don't you do an episode on how to put a wind sock on a microphone
haha. Yeah, I should have put it on. I do so little recording outside I didn't think about it until I was editing the video, by which time it was much too late. Peace.
used on a jeep ecu is dead....
???????????vaseline vs dialectic grease???????????
Sorry, not quite sure what you're asking. Vaseline is different than dielectric grease and should not be interchanged. If that's not what you're asking, please be a little more descriptive in your question. Cheers.
@@HouseOfHacks Vaseline and Dielectric Grease Electrical Resistance in Wire Connectors th-cam.com/video/pC2HVoHWNLA/w-d-xo.html
Excerpt from text right below video: ....Vaseline and dielectric grease are widely used in wire connectors of motorcycles and automobiles to keep the moisture out and prevent the connections from rusting and sticking. There are different opinions on how to use them and if one is better than other. The electrical resistance of each was tested and their effect in wire connectors resistance was explored. Both are NON conductors and slightly raised the resistance of connectors.....
@@tombouie Ah, I see. Vaseline is a petroleum based grease and may degrade some types of connectors. It's also highly flammable. I would not use it for electrical connections as 1) it may cause the fitting to get brittle and break and 2) if a high current causes it to heat up, it may catch fire.
@@HouseOfHacks Thks, really you should do a video on the compare. Vaseline on econnectors is a lot like sasquatch, ufos, ghosts, etc ; the myths just lives on, & on, & on, ..... , & on, & on, & oooonnnn
Yeah, that would be a good topic! Thanks for the idea!
You are showing a lot of your face: it has nothing to do with the title of this video. You just love watching your own face and hearing your own voice. You are showing houses, clouds, music, etc. Nothing has to do with what I need to see: HOW to apply grease. Can you make a video without faces, clouds, trees, houses, dogs, music, but which has one thing only: HOW to apply dielectric grease.
Thanks for the feedback. I'm not sure why you'd expect this to be about how though, the title explicitly says "what" and "why," not how. However, the companion video I did with Mike does show how at th-cam.com/video/N47kXxD_Rxw/w-d-xo.html
Hope that helps. Peace.
Overly produced video but can't afford a cheap windscreen for the microphone. Talk about fail.
You're in a minority.
Couldn't find the windscreen. Didn't think I'd need it. I was wrong. Thanks for watching.
how sad does your life have to be to talk shit on a 3 year old video.
Poor explanation.
