I'd like to say a huge thanks for this video. I've recently made a few new battery leads for my narrow boat using your techniques and I'm quite sure the end results couldn't have been better if I'd bought professionally made cables. Mind you, the crimping and cutting tools have cost me a packet and I'll probably never use them again, but if my wife can have more shoes than she has feet, surely I can have more tools than I have fingers...!

You did a much more professional job than another battery cable video I just watched the other night. You OCD is fine with me. It's nice to watch people do quality work.

I think this is one of the best tutorials of lug terminal mounting. I like the idea of crimping AND soldering.

Outstanding! Thanks - glad to learn about removing the lubricant on the outside of the insulation before putting the heat shrink on.

I wish I had more than one vote to give you as this is the best tutorial on this issue I have ever seen. And I have seen a few. There is a sea of conflicting and horrible information out there. You sound like someone who has done this many times and that crimp was a thing of beauty. I doubt anyone would believe that crimp was done by hand. Then you go and top it off with the proper usage of solder, that so many videos reject using as they are trying to use it improperly before the crimp rather than after, and this is just perfect. Thanks again mate. Subbed.

I never would have thought of brake cleaner before heat shrink! Golden tip, thanks a lot for that. I have the same tool and also noticed immediately that you need to eye-ball the crimp die sizes depending on the thickness of the lug etc. I tend to crimp, rotate and finish crimp to prevent the crimp from growing ears. I like the tool, still I hope I'm not tempted to exceed its limits...

Best cable making video here!!! Great Tools + Great Technique + Great Care = GREAT JOB.

Nice trick, twisting the solder. Great technique. Good video. Note that you are using a ROSIN-CORE solder, since you added no flux to the cable.

thanks for the British humor....always dry but funny...

I'm so pleased I found your video on this subject. I am about to start some electrical work on one of my boats and wanted to get this right. I have watched quite a few other videos and it's frightening how some people go about doing this. Without doubt this is the best video on KZfaq demonstrating how to correctly crimp battery terminals for marine applications. Many thanks. Subscribed!!

Oxidation and corrosion are a problem too. I do a version of this for battery cables and exterior elec. connections. I first slide two pcs of heat shrink up the cable (1 1/2" & 3") way up out of the heat. I place copper fitting in a vise vertical. Trim cable to proper length ( bottoming out in fitting). Flux fitting and cable and heat fitting and fill halfway with solder. Heat the cable end and quickly push the cable end into the fitting add more heat if the cable cools off the solder before bottoming in the fitting. I now crimp the cable end as this video shows. After cooling to touch, I coat the fitting and cable with silicone, slide the first length of 1st heat shrink (1 1/2") over the fitting/cable and heat, and watch silicone squeeze out, Next lightly coat the heat shrink and cable again slide the last heat shrink (3') over the cable and heat again watch silicone squeeze out, wipe excess silicone off. I have cable ends and electrical connections on my Semi that have gone through 6 seasons of mud, rain, and snow that are good as the day I did them.

Greetings from South Australia. Thanks for the excellent video. I will pass this on to a mate building a 3 million dollar place near the sea. I have suggested having his solar installer use marine cables and fittings.

Professional crimp. The crimping tool is a must have

I took a moment to sign in and subscribe after you hit that 50mm cut so nicely. Also, I appreciate rare teachers like you that are so hard to come by. Your purpose to educate is why I enjoy being the student!

the proper way to crimp! excellent stuff

Top job! Can’t fault it…….well you did burn the existing insulation…….but still one of the best tutorials of how to crimp a cable 😂😂😂😂👍

Quality content! This will make boating in my 4x4 even more enjoyable :)

I'm not a fan of using solder on a crimp connection. As a NASA contractor working on the Space Shuttle program, using solder with a crimp connection was not part of our workmanship standards. If the crimp is done correctly, there will be no space between the cable strands for solder to flow. When you slice it you would see a solid with no voids.

Best demo I’ve seen. Thank you

Great video, Dean. Fantastic seeing a perfectionist at work! Please do more videos on general maintenance of Yanmar engines, in particular 2GM20s. It would be great to know how much exhaust smoke is normal, how much blow-by is normal, how to debug difficulty starting. Also, coolant changes when the heat exchanger is connected to a hot water cylinder, choosing the right replacement belts. And so many others...

Excellent vid BLM showing a true craftsman at work. My only suggestion (from my electrical bg is to be sure the lugs are sparkling clean inside and degreased, could even tin the tube inside beforhand but this must be done carefully or too much solder will reduce the bore and may make cable insertion impossible. Also smear some solder flux on the strands before. Its all double security as if solder does flow predictably and easily using only a small amount, you are in trouble with a dry solder joint - cut off and start again

Excellent video. It’s nice to hear your opinion about using a small amount of solder...to avoid corrosion

Fantastic demonstration. well done

Thank you for this tutorial. I am making a set of new cables for my 97' Jeep project. This was just what I needed.

+1... A nice critical path to properly crimp cables... Cheers, Vail, Colorado

First crimp that really looked good to me. thanks KC2-AGT NY

Great information from the Isle of Man. Thank you; I learned some important pointers. And you have great fishing on your island, too! I spent a couple of weeks with you watching the 2019 TT races and I fished with a great local guide, Geoff Thomas. It was a wonderful experience and I hope to return in 2021 if the races are back on. That's after I replace the 32 solar batteries and cables to our solar system.

Try making a solder dip! You can use a torch to melt solder within the cable end on a metal vice so thiers excess solder, (or you can use a wood work bench table if you are careful) then you can dip the cable after it is stripped and hold it in the cable end until it cools! You can use the cap of the torch to put your flux in or paste if you needed before soldering to make sure the connection functions the way you would like for your application as I would for mine! It won't break or budge! I remember old internet non sence before! Always go for the quality videos and hope people give you products that work! Finding out what to use for what takes years and hard is an asshole and not kind! Hope everyone is having a nice day

A perfect teaching video! Thanks for your tutelage.

Excellent tutorial. Thank you. The only l step I suggest is line up the lug so that when installed, the cable labelling is showing up/out for easy reference.

thanks bottom line ( just subscribed ) i intend to use these method on my welding earth cable. frank isle of man.

Hello from the high desert of New Mexico USA 🇺🇸. I just found your channel and I liked and subscribed. Keep up the good work and stay safe

absolutely the best tutorial on this.... thanks so much

Excellent tutorial!

Awesome video mate, just running power to the rear of our camping car and this video is very informative, love from Australia!

Did the same on my boat installing a second battery/ charging regulator. The strength in the connection is the crimp.

This man calibrates his eyes every morning

Great explanation and quality video!!!

I am always looking into better ways for different jobs My SUV camper I upgraded my wire to 1/0awg copper welding cable to withstand extreme heat I used a hammer lug crimp And a fine painting brush of dialectical grease Boil point 392° F (200° C) at the lip of the Lug and exposed wire (very thin expose) This seals the wire from air And moisture being water resistance But not waterproof Then my shrink tubing. The result of this method 7.5 years later No green coloring Or white corrosion on my other builds I run 2 batteries one being a 200amp 12vott that runs off a high output 145amp Alt, 340watt solar panel, And a 13amp 125volt AC port plug for shore power And all the accessories This works for my Freezer/fridge slide-out cooler on 12v 3 sets of 2 lights 12 watts lap top Or mini air conditioner 8hrs

Thanks. C'est une méthode qui me convient : facile, efficace !

Nicely done. Thank You

awesome video very helpful cheers

Nicely done mate.

Very nice tutorial

Great demo thank you.

great job ,thanks

Excellent tutorial

Nice job.

Hello, a soldering trick that I thought of is, to prepare your solder before use is to clean off the surface oxidation. To do this I use a SCOTCH BRITE or similar cleaning pad and then give it a wipe on a rag for good measure. This way when you use the clean solder you will not take all of the junk into your new connection. Cheers and stay well.

Best tutorial on KZfaq!!!

Thanks for sharing your skill and expertese. I have seen mention of additionally using dielectric grease under the heat shrink. Do you have any thoughts - beneficial or not?

Usually you want to strip justa bit more than the depth of the lug and have a small gap between the insulation and the lug a couple of mm will do for extra strain relief.

Thanks. From singapore

Very nice video indeed

Thanks, Dean

nice job

Hi, great vid it has helped a lot. I, like another in the comments was fixated on the Marinehowto site on selecting tools. Are you still using the same hydraulic tool for crimping?

Ultimate demo....

Top notch! Thank you!

Thanks for the great video - from a mech eng getting into 12v electrical

good video

😀👍🏿Good Stuff,GreatTips

Nice job, I perfer to use double wall heat shrink tubing, it comes with a sealant inside, or glue some call it. It is much thicker and the sealant provides extra protection from water and corrosion.

Very imformative!

Thank you :-)

Thanks for your demonstration . There's a guy on the Tube who reckons that the small hole on the ring side of the terminal is for the purpose of inspection. Not wishing to show any disrespect to anyone's sincerely held beliefs here , it would seem more likely to have been designed for solder - as you have shown. Got to try and join together two ends of earth cable and bolt them to a stud on my daughters car . Without a crimping tool !

can we use epoxy such as 3M DP420 to fill the inspection hole?

What brand of a heat shrinks you used in the video?

Hello, I have another question for you, what connectors and crimps do you generally use in the marine environment. I am looking to clean up some wiring and electrics on my sail boat. Should I being using nylon insulated (double crimp) or heat shrink nylon connectors. Again the marinehowto recommends expensive crimps, is this really necessary to get a good crimp? Any help appreciated. Been looking at Knipex and wirefy off amazon.

thanks for the info, made me a little smarter today. Question, a battery is 12v, yet i see guys putting 4/0 cables is this correct??

How to bend the battery cable terminal lugs into a perpendicular form? Like you keep it in a vase e. g., how to bend it, with what? Do you need a special tool? I'm afraid to brake or scratch the new expensive cable I ordered. I need to bend the positive cable end, bcs such is the original form on the alternator connection. Thank you for the film.

Love The isle of Man My Onna is Manx Grandmother

Hi, I don’t know if you can answer 5his question but, Can you use old 50mm2 battery cables on a new installation if you change the lugs

Hi I am BRIAN FROM THE UK where can we purchase hi quaintly cables and the fitting ! Could you list them cheers !!

material list would be nice

Anyone contemplating this should check local rules. In many applications soldering is NOT an approved method. The reason being the potential for corrosion.

Where am i able to purchase those kind of terminals??

Fine job except for the solder

What do you think of using metic dies for AWG terminals? I see there is a significant difference, e.g. 25 mm squared is suggested for a 4 AWG terminal but 4 AWG is 21.15 mm squared, not 25.

nice vid you didn't need to solder

No flux?

I could feel the heat it was so close and I tried to blow out the flame.lol

No need for flux I suppose? I would have used flux

Wait, so you guys call a flashlight a "torch" and a blowtorch a "blow lamp"? The King's English sure is funny.

No flux???

The proper way is to not use solder.

You really should put your title as "soldering" terminals...
