Pay attention everyone! I had to pay a ton of money back in the day for the knowledge he is giving you right now for free on KZfaq!

Thank you for posting these videos!

I have now put much of what I learned on this series into practice on my yacht ( Island Packet 445 ) and I am very grateful for the knowledge. Thanks!

What a great resource. We really appreciate that you take the time to do them.

Really appreciate the videos. Used to install alarm and other low voltage DC systems, home theatre, coaxial, phone, intercom, etc. Luckily apprenticed to someone with a similar mindset about installation mentality. The videos are much appreciated and I'm sure the boat owners that are your clients are more than satisfied. Recently took up sailing and the info is invaluable. Thank you!

Great seminar. I hope you keep posting. Thanks

Thanks you a lot for this amazing job!

my Uncle was the man who pushed the Ark into the Warehouse at the end of the film, film in Pinewood Studios England, just a claim to fame i cant resist. Thanks for the lessons, very kind of you to post.

Thought this would be boring, but it was super educational and funny. Thanks.

Man I love KZfaq and people like this! Thank you guys so much for posting this seminar! Seems like this guy really knows his stuff.

NOTE if you just found this - after a few minutes, I was about to skip ahead to get to the 'good stuff' - how to do this and that. But didn't and am SO glad. Jeff lays out a lot of background that tells you how you should approach the whole area. When I got to parts like fusing, I felt well prepared for the specifics and prepared to make sure I did a proper job when it came to it

This video series is just awesome. I have Nigel’s book and will continue to use that alongside to reinforce my understanding, but the quality and passion of Jeff’s teaching make the whole subject come alive and I feel like my learning curve is near vertical!

One of the best presentations on Marine Electrical I've ever seen in any format. A digital precis of Nigel's book. Really well done.

This is great! I'm watching all before I completely gut my new (to me) boat's electrical. It's so very terrible. It's been hacked together over the last 37 years. Looking forward to doing the very best I can and getting it into a good state.

Really good overall introduction to all a boat's electrical components. Jeff delivers in plain English and in an engaging and entertaining way. The 6 hours flew by. Thank you Jeff !

I am so happy I found this!! I plan on upgrading the electrical on my boat soon. I want to do it "the right way" the more info I can get the better. Thank you!! I look forward to the rest of the series!!!

I've only watched 20 minutes of this and learned 3 things I didn't know. Well done.

Wow, novice marine electrician, your videos are really helping me learn more and more. I appreciate your service!👊🏽💯

Thanks for the series. It was great that you started out with “war stories” to instill the needed safety of electrical, water, and fuel.

Some of the best electrical caution and advice. I own an electrical company.

thank you I after owning a sailboat for most of my life and being frustrated with my systems I see a path to understanding

Thanks! I'm an entry level tech, just finished my training, started working at a marine shop and found this part absolutely interesting. Actually I want to take my time over the whole course and taking notes. Once again, thanks, will be watching your videos.

Great Instructor.

I love this video and want to learn more and will watch the whole series. I do have to disagree on one point though. Almost all car manufacturers now have a distribution block basically built onto the positive of the terminal. I've seen 5 fuses branching off a positive terminal. I'm wanting to transfer my 25 years of auto electric knowledge into the marine world so I really appreciate your videos!

Very Knowledgeable and Good Teacher!

Great job! Congratulations

Hi From a marine engineer/ industrial electricians back ground, The subject that I would start from in DC battery installations as a beginning is the available prospective short circuit fault current and its effects in a fault situation. And next the explanation of earth fault lamps , and the most important is a volt meter showing the DC volt at present, one on the house batteries, and one on the engine batteries, most important. Very few boaters would understand and the above three most important points on any electrical installation. best of luck Allan in NZ

Guys that get impatient: you've got to remember that he's standing up in front of a class- maybe even after lunch- and not everyone is a Spring Chicken. Try as they may, they get sleepy and distracted, particularly if the material is tough, at first, to comprehend and integrate. A good lecturer will take the temperature of the audience and respect their attention span. Some times, an anecdote or two will allow the class to coalesce and get caught up and he'll get on with the information. My guess, Highliner, is that marine electronics are not as daunting to you as it might be to a newcomer. Patience, Skipper. We were all newbies once.

شكرا جزيلا لقد استفدت كثيرا من هذا الدرس

Thanks for this, Jeff

Hi there I used to have a mental block about electrical systems and thought I would never understand. After fire on boat (new to us) last year I forced myself to learn from the experts. Nigel Calder book as well as hiring a marine electrician for advice. I've only watched part 1 of 6 and look forward to the others. Don't listen to the naysayers, your presentation skills and content are fantastic!

Much Thanks 🙏, your experiential tutorial, has me almost feeling like 👍🏻 a purposeful bright spark ⚡️🦘

You are the best!

I'd say that I'm rewiring an old new to us sailboat but the reality is that I'm "wiring it". Out with the old and in with the new. I'm pulling all of the old stuff out. Old stuff discoveries 1. Shore power inlet ground disconnected. 2. Heat shrink butt connecter that was heat shrunk but not crimped. 3. Terminal connectors, yes plural, that did not pass the "pull test", simply came apart with a slight tug. 4. Abraded wires where the wires were exposed. 5. Headliner (ceiling) light wires that were taped together with painters tape, not so much as a butt connector or electrical tape. Thank goodness I pulled the headliner panels off. All of that I tore out. 6. Quick disconnect wire to a USB outlet that broke free of it's quick disconnect female terminal. 7. 22GA wire butt connected to 14GA wire butt connected to 22GA wire again and of varied colors. The only remaining old wires are dead wires (not hot) and simply in place as fish lines. What a disaster. 1977 sailboat. As Jeff says "nothing is ever easy" and "Don't trust anything on an old boat".

As a future cruiser, the electrical system is one of many areas that I need to learn and this video is a great help. I do have some experience with teaching and i would gently suggest that you try to get into the habit of repeating the questions you receive from the class so that your your wider audience understands your answers.

Thank You!

Yeah, I get that. This is a real important area and what you're trying to do here is great and all but this is going to be a long day. Following.

great job, I have seen installers do the same wiriing work you show in the bad wiring photos

I thought I'de seen some freaky things as a land-based electrical student , but some of this is making my iris's curl.

Thank you

Your fuse failure at 43 min is exactly what happened to my buddy. It was a factory fuse on a minkota on board charger. We plugged it in at the dock after fishing and i caught a faint smell of burning electrical components. After some hunting i saw a whisp of smoke come out of the fuse holder. The charger was bad and over charging on that lead. The fuse failed closed. Always trust your nose.

I need to replace all my boats electrics, when I get some time today I am going to watch the whole series

Will the thermal camera overlay a chart? ... I'm assuming the tech is not yet there..

I worked in the marine industry for 15 years and then decided to become an electrician. I’ve been an electrician for 6+ years and now I’d like to get back on boats and become a marine electronics technician.

Very interesting and clear way to explain it. But what happened with your laptop connector that seems to be wrapped with masking tape?

SPOT ON

if you have 30 amp shore power what kind of fuse\breaker would you use? 30 amp? or do you size a bit highre like 40 amp? My boat has shore power but no breaker....

Great video, thanks a lot for posting it!! Do you have the mentioned PDF file of the slideshow to share with us?

Where would you consider the best place to connect the + from a hour meter on a Volvo 2030?

Thanks for sharing this video. Any pdf file for this?

Dumb question, but at 7:18 you say “that’s where ____ comes in.” What did you refer to??

Hi Jeff, A small electrical question. To do with continuity. I get continuity with the bilge water and (only) the negative terminal when the pump is functioning. Is that normal? When it's in auto or off there's no continuity. Which is good. What are there any consequences to this for my copper rivets? Keel bolts? Greetings from Berlin

Yeah people don't realize that the ground is the most important thing in DC. The power actually flows through the ground

Patreon? Great video. I’d donate.

You mentioned in one of your videos how a cheap inverter can cause galvanic corrosion in our underwater metals but I listen to these while trucking so am not fully absorbing everything. I just bought a 43 year old sloop and I need to be able to charge my laptop. Is there a low cost safe solution for me? The purchase price was a huge hit on my finances. I'm going to be cruising BC all summer on the hook using alternator and possibly solar panels. Advice? 😀 Thanks so much for these videos by the way. I've learned my electrics are a liability but I should be able to disable everything I can't get up to code 😃🙏🏻

just asking is led light bulb can be use for emergency lighting in the yacht? is that solas approved or any flagstate approved?

Excuse me sir, PV = nRT only applies for ideal gasses

great video. I am 16 and I want to become boat electrician.

Not using AC in the summer? It's 90F+ every day in the summer where I am. Took me a moment to realize he meant alternating current and not air conditioning.

Cross thread is the best thread @41:17

B.O.A.T. "Bust Out Another Thousand!"

MC cable running with no connector will Caus A Short

A lot of times it's the owners that cause the problem cuz they don't want the contractor to do a thorough job because of costs.

I wonder if you can recommend a qualified marine electrician to help me in Connecticut. I have a 1970 wood trawler that has so many wire issues and I know nothing about DC electric. Example, solid strand wire, the old house wire that is incased in metal and has paper insulation, no heat shrink terminals or shrink wrapping of wire. Five switches run the whole boat! I could go on and on. If you know anyone in Connecticut that can help me please I want to hire a qualified marine electrician. Thanks!

Would be useful if questions from the audience were repeated as they’re largely inaudible. Would help put the answer or comments into context

I wonder why so many dislikes on this video? It seems great to me. Does he make some mistake explaining some of the things ?

Dude said some real shit around 4:00 mins in. ..

I came to this video because it was listed as "basics". I am still looking for a video, or series of videos, that is basic. Cote asks us what we're seeing looking at these videos. I have no idea. Also, Cote uses much terminology without defining any of it. Again, I was looking for a true basics video. Cote has knowledge that I desperately need to improve the wiring on my boat. If only he could really get to actual basics. Let me help: I do not know what circuits and wires are supposed to be connected to or not. I do not recognize anything these wires are connected to except for the batteries. I cannot tell which wires are grounding ones. These photos would make good quiz material for students who had a little more understanding of electrical. So, Cote, please help us who know we probably have electrical issues, but don't even know enough to know who it correct or incorrect. I would hazard a guess that some of the bad work you cited was done because the boat owners knew less than what you consider basic.

Conductors were cut to fit terminal. No no

Mau donk kerja di kapal? anybody can help me? really interest to work at ship

43:12 that’s an impressive failure

🙂👍🏻👏🏻👏🏻👏🏻

PV=nRT does not apply.

its like he took all these photos from my boat.... smh :P

C'est un caulisse de grosse mouche vers 52 minutes

You seem very knowledgeable about marine electrical which is great. So, maybe it's hard to really go basic. I found it difficult to follow your use of terminology because I know NOTHING about electricity. I need something that's is truly basic as I know the electrical on my boat wasn't done safely. I really want to learn the correct way to wire my boat, but this seminar is speaking above my level. I used to teach university level courses in my own field, so I know something about disseminating knowledge and training people. In your seminar, you spoke to those who answered questions not the ones who remained quiet because they didn't want to reveal how little they knew. It's important not to gear teaching/instruction to the most knowledgeable student in the room.

I really wish you could start with a basic visual of power needs and resulting wiring design options. Put the components on a sheet of white plywood, mount them and wire them together....then you can go back and discuss best practices for each detail. Folks need the blueprint first....who would ever go about any wiring job without a crystal CLEAR map of what you are about to do....I know I dont. WHich makes watching hours of video about minutia pointless if you cannot see the design map.

Insta subscription

16 minutes in and he has not started to cover the topic. No wonder it is a six part series.

It's 2021, you are a better presenter now, right. Start speaking to people as if they know nothing because many new guys don't. Start from first principles, like Nigel, and you will be magic. You know it, but you lose many viewers by not starting from the first principals. Maybe I need a more basic course, but I think your audience would be larger if you think most boat owners know very little about this stuff.

Talk too much and no content

No long winded questions... How about less long winded lecturing that doesn't apply to the topic??! Jesus...

This video has a misleading title! It has nothing to do with "marine electrical basics" but an hour of highlighting completely ignorant mistakes and careless electrical installs. Waste of time for anyone who has knowledge of electrical theory and installation and cares about their work !

Too much talk and get to the point for god sakes I dropped in the middle. Waste of time.

13 minutes and 13 seconds into this and I am out. You have said nothing other than there are no stupid questions and don't try7 to invent your own electrical system. Peace Out
