What you NEED to know about Boat Electrical (Part 1)
HTML-код
- Опубликовано: 26 июн 2024
- All sailors and boat owners should have a basic understanding of 12-Volt DC systems, basic electrical concepts, and the tools you need to maintain and fix your boat's electrical system. When you're traveling and something goes wrong, you can't just call an electrician-YOU must be the electrician. In this series, we want to empower you to do that. So today is the beginning of our multi-part series on Boat Electrical Systems. We'll start with the basics, then work our way up to troubleshooting common problems.

Thanks for watching (and commenting) on this video series. If you have friends that you feel could benefit from what's presented here please consider sharing a link to this with them. I'd really appreciate it.
I just bought a sailboat and the electrical is one of the things I have no clue how to sort out and fix. Can't wait for lesson 2
Talking to a boater friend, he mentioned watching your videos. He is an A/C guy and was impressed with the system you put up. Great services to the community. Love you guys.
Clark is a rare breed. An Empathetic Genius = someone that can explain advanced concepts translated into simple terms paired with a want to share. Thanks!
Ahhh.
Capsized best describes what happened in my life 5 years ago when an MS relapse disrupted most every facet of comfort that I knew. Over the months (and years) that followed, even more crumbled away. As I have been collecting the pieces that remain, …what is missing? What is this longing in my heart? It is to chart a new journey, one that I have dreamed about for most of my life. My goal is to be living on my own sailboat before the end of 2023 (within the next 17 months). I know that finances are such that I will need to find a good “fixer upper”. Where to begin and how best to proceed? Watching a number of sailing videos on RUclips, I recently stumbled across your channel. 🙏 Thank You so very much for the content you post. It is helping to provide the confidence that I will need to begin making this major life transition. Though I have very limited experience sailing in the open ocean, it is then that I felt most alive. It is my responsibility to myself to keep progressing towards this new reality.
I like this person ALREADY ! He talks like he understands WE MAY NOT KNOW ELECTRICAL JARGON.
PLEASE, TALK TO ME LIKE I'M 11 YEARS OLD. THST IS THE BEST WAY TO TEACH.
I do electrical engineering for a living and Clark has done an excellent job teaching in this video. He's a natural! GREAT JOB!
Thanks J.
Always good to get reinforcement from pros. Part of me always wonders if I'm misapplying something. I don't script these really. I just start talking from the top of my head.
Phew, a single thumbs up is SO inadequate for this educational video. I’ve never enjoyed maths so much, and I’m actually excited about how I can use this information in a practical way. Thank you for your excellent teaching skills.
So nice of you to say Alex.
Please share this playlist with your friends
Nice. The biggest help will come with video of the meter and how and where it is applied (showing good and bad circuits and connections). That is where most tutorials lose me...when they talk about it and don't show it. As a visual learner, that is key. Thanks
Got your hint
This is excellent. Thought it was too basic for me, then quickly realised I was wrong.
We will go deeper.
Just started watching this series now and actually feel like the info in being absorbed, so thank you!
Thank you, thank you, thank you for producing these videos. I'm in the process of designing and installing an electrical system on a 50 year old 30' sailboat. I tore out the rat's nest of wiring that infested the boat and I've got just about everything I require to start my install and I can use all the knowledge I can get.
Fun times await
I loved your video. I now have my sailboat on a mooring ball. No shore power. I had to install solar panels. I realized how DC power is so important. Thanks, I'll keep watching.
Thanks Luis
I need to buy you many beers. The two things holding me back from buying a liveaboard sailboat are the electrical and engine maintenance. You sir, have given me the confidence to keep learning and make my dream a reality. Thank you!
Well I was going to say there is a Patreon link in the description below the video but if you're Steve all just say thanks as I see you just did
And you're very welcome
A happy upgrade to the usual sailing videos from youtube.
Thanks Torch.

Wow! In 20 minutes, you made more sense than my physics professors ever did. You need to run graduate seminars on common sense electric design and troubleshooting. THANK YOU!
Well done !!! As an electrician, and familiar with harsh environments I would like to see you add a mention of dielectric grease. My only critique.
Do it!...,the first instalment is the clearest explanation of basic electric terms I have ever seen 👏
Thank you
My grandmother believed electricity would leak out of an outlet if it did not have plugs in both holes. I picked up her suspicions (though not beliefs) and so avoided understanding electricity.
Love this. Sent a link to my granddaughter, who, having just graduated, is thinking of becoming an electrician. I am guiding her to specializing in marine electronics.
By all means, finish the series. Hope to anchor up near you some day. You are doing good work.
If you see Temptress in a bay. Stop over.
I'm an aircraft mechanic and i'm here to learn. looking forward to it.
I learned this stuff in school 40+ years ago. I wish you were my instructor.
Thanks Jr
Looking good Clark, glad to see you completely recovered from Covid. You look years younger than when you were sick.
Thanks. Back is also getting better.
I'm never gonna fix the wiring of a boat, but I'm about to be working on a post apocalyptic book and one of the characters needs to be smarter than I am now. I actually found you guys because I wanted him to fix a refrigerator. Seems like a good way to make friends in a wasteland.
Yes I can identify with that character.
You might find this one useful.
ruclips.net/video/AEISxhk43o0/видео.html
Thank you very much, The black art and mystery of electricity is being solved.
Hello Clark, please continue. Who knows in the end you can build a electricity course. You already have one student interested. I am curious for the next lesson. This one was great. Thanks so much, Paul
You're very welcome Paul
I am an airplane mechanic (school 20 years ago) This was a great refresher and better taught than A&P school!!!! Good job
By the way I havent worked on aircraft for 10 plus years
Thanks Joel. That was nice of you to say.
This is exactly the video (and hopefully series) that I need to see right now in my boating journey! Thank you!!
Glad you found it Cody
Really great information. I have worked with electronics my whole life. That equation is core to designing anything and it's so simple. People are afraid of electronics but there are only four basic parts and that equation to understand most all of it. Great work. You are providing real information to help people so they can become self sufficient. Give a man a fish and he eats for a day. Teach him to fish and he eats for life! Bravo!!!!!
It's not about the views, It's about helping people! I hope this series continues to develop.
PS I really liked the knife sharpening video. I ordered one of those!
It's a little about the views...
I'm just starting the planning for rewiring our 1980 Cal 2-25. Thank you so much for creating this series. It will be so helpful and much more fun than studying books.
You're welcome Dave. I'm sure you will do fine
You always did it perfectly when you explained the three electrical fundamentals, almost until you slipped your tongue and said "amps" in the same category as voltage and resistance. But, to your credit, the text on the screen clarified the difference. Unfortunately, you do not use the unit of measure [Ohm, V, and A) to describe what you measure -- many people can not make up this simple difference which creates more confusion. This is just little detail in an otherwise excellent episode and channel. Cheers.
Had to teach one of my techs about voltage drop after he tried to order a third starter for the car being repaired, saying they were all defective. Once class was over, he replaced the battery terminal end on the positive cable that was dropping ~11 volts under load (invisible corrosion hidden between the copper and lead inside the factory-made terminal/cable) - enough to kick the bendix out into the flywheel but no amps to crank the engine. Back to basics, buddy! Oh, first too!
Cars and boats, most of the problems are corrosion or a broken wire.
@@jonathanwetherell3609
Used to be in broadcasting. If we lost program the first remedy was to whack the jack plugs in and out of the jack. (And don't clean them with Brasso, ever, it leaves a residue which isn't that conductive.)
If that didn't work then a new double ender lead to replace the original. If that solved the issue then a loose knot in the old lead and leave it to maints.
If that didn't work it meant the gear itself was duff. A very rare occurrence indeed.
Ergo ALWAYS check the wiring or connectors first.
Battery connections, especially, are worth doing properly as that's where your bilge pump gets its power from.
You can work out the rest for yourself.
Constant equipment and especially diesel issue. Many times all I do is fastidiously clean up every contact in a circuit.
I would love for you to complete this series. ELECTRICITY !!! And really like your videos. I wanna be a capable cruiser!!
Thanks Brandon.
This might help
CAPABLE CRUISING GUIDES: ruclips.net/p/PLsT7_jPsZM5pFpq8RX0oxjibknM2Gz361
Very very thanks Clark. I’m not a boater yet, but I’ll be one soon and this videos series are perfect for a beginner like me. Thanks for keep it simple.
Glad it's helping
Wow, that is all i can say is Wow. I am a mechanical person, if it moves, if it has pressure, and it flows...I understand it. But, electricity and electrical...I always considered black magic. Until a friend explained it to me in mechanical terms. And I was amazed how much it is like plumbing or hydraulic systems, just in another universe. You video has explained it even more as to a boat aspect of it, and that is the info I need. Carry on my wayward son.....
Thanks Michael. Glad it helped
Awe yeah! The much anticipated series! Electrical or as I like to call it, magic!
PFM
i like electrickery
Watched other videos and read a bit to try to figure out what wire is needed for what device and was not really sure I understood. Your discussion really cleared it up for me. I'm always impressed on your ability to explain things in a way that makes it easy to understand. One of the reasons I love your channel. Will be looking forward to the rest of this series.
Episode two is about wire. Just filmed it yesterday.
Excellent primer Clark! Thank you. I have a degree in electronic engineering (a few decades ago now 🙂)...I wish my lecturers back then had the ability to explain these concepts as well as you did. I'm looking forward to the rest of this series!
If there are those out there who still had some difficulties in understanding the principles, a couple of things I use is to think of electrical circuits like water pipes...Voltage is like the pressure in the pipe and the rate of water flow is the current (Amps)...bigger pipes (thicker wire) allows more current...an electrical switch is like a tap. When it comes to resistance, you can also think of this like rocks disturbing the flow of water in a river...more/bigger rocks slows the water flow (resistance).
I have used that water flow method to explain it to some and would use a balloon in line surrounded by needles and when the pressure gets to much it expands and pop's into pieces to stops the flow by a open in the circuit for the fuse/circuit breaker
Your content is some of the most useful content on youtube for boat owners. Thanks for posting this stuff!
You're welcome Tim. Please share our links around. It helps a lot.
Superlative explanation, with one caveat: Many boats have both DC and AC circuits.
Yes. I guess we could get to that.
Excellent lesson. I’m a journeyman lineman and the triangle equation is the way I learned. I use it all the time in my work.
Thanks Tyson.
When was that? I think I learned this before the idea got out.
I was an apprentice 2007-2011 in mountain states line constructors. We call it ohms law.
It may not have had the triangle but was expressed as V
I R
As a very spacial thinking guy this representation appealed to me.
Yep it's certainly ohms law. I just realized I forgot to say that in the video.
It’s fun watch girls on the beach, but these practical videos make a difference in one’s ability to go cruising!
this is fantastic!!!! so so excited for the rest of this series you have no idea! learned so so much in one video
Thanks Melanie. So glad you liked it.
As a soon-to-be boat owner, I love the deep dive videos. Keep up the good work, Clark!!
Thanks Mark
Perfect, perfect perfect! I am reading Don Casey's Complete Sailboat Maint book and just went through the electrical chapter. This video made it very simple to understand. Can't wait to add the series to my watch and re-watch list!
Well done! I used to do small boat electrics before Covid. I will share this with my ex customers.
Thank you
That is amazing. I never understood any of this but it completely makes sense after you explained it. 100% correct on the quiz
That's great Richard
Hi Clark and Emily.. perfect Clark. Just like sitting in class..didn't realize ohms was measured in divisions of feet.. and when you explain resistance , explain what zero resistance or a diminishing value of ohms mean in terms of heading straight towards or what is called a short in your terminological power points.. Wish all my teachers were as non condescending as you.. excellent scientifically tecnalysizeing introducing conductors and the relation to insulator elements.... Plastic and metal is exactly what I seem to recall as I remember reading when I began teaching myself all the electrical theory myself to do refrigeration..and that electricity is just a force or the differential interactions between Electron charges of the 108 elements on the chemical chart of known elements in the world...can't wait for your next ones Clark.. you both take care now.... You both have such an electrical magnetism about you... Esp Clark.. neat to see the comments from Brian .. I took electronics and loved his explanation of compartmentalizeing varying degrees of voltage needed for the work in watts needed... You two should start some cool inventions between yourselves... like making say guitar pedals... Or any number of a million things. ..
.
We do have some.

love your deep dive videos Clark, and i'm so weak in electrical. i'm counting on you to help that improve! Thank you so much, I will watch them all
You're welcome Michael
Perfect! Getting ready to buy a boat and want to learn everything so I can fix myself. Thank you!
Clark, as an electronic engineer myself this series is SUPER, excellent job sir! Super kudos for the entire series. You have demystified electrics for the average boat owner and provided the tools to perform their own maintenance and upgrades!
Thank you
One thing if you have a clamp on amp meter you can increase its resolution by putting more turns through the clamp 2 turns doubles your current reading ( divide reading in half to get actual current)
Many times I do 10 turns on lower amperage then just move the decimal point 1 place to the left.
I'm pretty confident with 12v wiring but I still found this video interesting and useful. Thanks, now I'm on to part 2.
Great start of an important series with a master-class presentation. After watching other sailing channels showing electrical problems, solutions, and/or general electrical upgrades and such, the terminology and graphics (that are mentioned and/or rarely shown), make viewing them a half-wasted experience, since it is undecipherable in the basic aspects. Thank you SO much, for this opportunity to really learn how to understand all this. Yes, more, please!!
Wow, thanks
Hi guys. Only just found you on RUclips and I'm chomping my way through your excellent videos. I've aspirations to become a full time cruiser in few years and I cant wait for the rest of your electrical series.
Thanks Chris. Happy binging.
Nice job Clark. KISS! Lol.
I do hope you speak to how resistors are used in circuits to provide a "local" voltage for a particular component or function within the circuit.
I also hope you offer your viewers other avenues to further the inquiring mind on the subject. There are many good options right here on YT as well as in print.
Super fun subject. Looking forward to the next installment.
Gee, Clark & Emily i know that it`s off subject but this video highlights just what a really great job you did on the interior refurb of the boat. It looks great. Respect. 👍
Thanks. Yes we are very happy with it. We might to the other cabins this fall
EXACTLY the education I need right now. Excited to repair my own electrical issues. Ears open Clark, GO GO GO
Thanks Steven
That triangle is a thing of beauty.
Yes. Surprised I hadn't seen it before.
You make a complex subject matter very easy to understand! Thank you kindly! Take Care
I haven’t even watched yet and I’m so excited to find this. Thank you, skipper!
I hope the series meets your expectations.
I have at least one more important episode to produce. I need to include a friend who just got back into the bay as he has an issue on his boat we want to address.
Very good explanation. Important also to consider heating in the wires, and different wire types by their ability to handle heat and other types of degradation.
Yes.
Hi Clark. Began to follow your channel for some years ago but lost touch. Now I found this video, and the videos with lithium batteries, as I'm in the process of installing lithium batteries on my boat. Thank you so much for making those videos and so good!
You're welcome Mike.

Been looking forward to this series for a while, ever since you mentioned you were doing it. Thank you!!!
You're very welcome, Matt
Great job 👍 I just aquired an isotherm DW65 for my 33 Pearson. I have it connected to 800 amp hours of battery (probably overkill) on 4 gauge wire. The explanation of the resistance was stellar! I just feel I need a big wire for longer runs but that made it so clear as to why. Please keep doing the deep dives they are great for guys like me doing the diy installations.
Very informative and easy to understand. I’m in desperate need of all this knowledge. Thank you so much for sharing!
You're welcome Teresa
I am or was an instrument electronic technician at a nuclear plant in MN so thought I was fairly smart until my son bought a boat in FL. It is fairly old, 1983 Tiara 3100 with two merc cruiser V8 motors with direct drive props. Each motor has it's own 12 v battery. The water temp gauge on the port side motor went to max 250 deg while the engine was not hot. The gauges in the dash share the power as they are hooked in parallel. I thought this would be a simple fix but was wrong! After changing the sensor same problem. Measured resistance and it agree with the chart at ambient temperature 450 ohms at 100 degrees and 1000 ohms at 60 degrees. Put the new sensor wire from the port side gauge to the starboard side and it went to max. When I didn't install the sensor the gauge read just what the correct temperature was but as soon as I installed it in the motor in maxed out again. I ran a jumper from the ground side of both batteries to each other thinking there might be some reason the resistance was getting less but that didn't do anything either. I am totally lost on what is causing this problem as I don't know much about salt water boats or inboard engine electrical systems.... Don't know what to even look for next!
Hi, @Emily & Clark's Adventure ! Congratulations and thanks for explain and sharing, with simple words, your knowledge and experience. Fair winds and seas!
Glad to hear you liked it Miguel
Looking forward to the series from Nova Scotia. Even though our boats are in the water for a few short months, finding electrical issues in the spring is exciting.
Corrosion is the primary electrical problem on a boat. Caused by the combinations of moist air, current and poor installation. If moisture can get between any electrical junction it will probably fail, especially if the materials are dissimilar. Very rarely are junction posts and cable ends(lugs/terminals) made of the the same materials. The most important thing that 95% of every manufacturer and experienced marine repair technician omit, is the use of a simple antioxidant. A small dab of Noalox between the contact surfaces of a connection will keep moisture out and make it outlast the boat! Even the use of top of the line Ancor brand tinned lugs, adhesive lined heat shrink and Ancor wires are comprised with the omission of this one little step. So close, yet so far.
Note; you may wish to avoid Noalox on the threads because it could increase the tension on the fastener due the decreased friction while torquing(or factor in for it). It can also make the fastener easier to loosen under vibration without lock washers so limit the antioxidant compound to the contact surface in these cases. Just be aware of the potentials. Noalox does act as a lubricant.
Lucky if other boaters use dielectric grease. People think I am weird at bringing in electrical industry antioxidants. So I am not the only one.
@@braithmiller
Lol
No, you’re not the only one, there are too few.
Interesting to see how you teach this. So far very good. Happy to have a resource to send people to or crew to get educated. The majority of others either seem bewildering or so dumbing down they aren’t educational creating more ignorant electrical workers. Thanks
Happy to hear that.
This was tricky. There are a lot of chicken and egg issues in this. I had hopped I had found a way.
I think a video on wiring a panel proper wire colors and ways to secure and route wires would be really useful. Tips on a neat well thought out installation.
I also think a video on how to troubleshoot would be great.
There is a video coming on how to find voltage drop in an active circuit. Really useful.
I'm afraid I'm not qualified to show neat wiring installs. Take a look at my battery AC video. Embarrassing.
Good stuff Clark! Keep it coming
Great video, Clark! Clear and comprehensive. Thanks!
Thank you
Looking forward to this series Clark,always enjoy your teaching style,thankyou
You're welcome Peter
Great post Clark ⭐️
I've been needing a series like this. Electricity has always been so mysterious to me. Can't wait to learn more. I will share this. 🌞🌴⛵️
Thank you Gef
Outstanding as usual and I shall look forward to the next one. Well done for making it easy to understand.
Thanks Mark
Definitely enjoy your deep dives. You video on VHF radios and antennas was really informative and really made things make sense.
Thanks Nathan
Clark...this is pretty ambitious of you...lol. But its going to be great! Even though I have a decent amount of experience I will still be watching each video. You always have a way of explaining things in simple terms and its very helpful. You are so right regarding the knowledge = freedom. I really dont know how some boaters do it without this knowledge. Its just too expensive to pay for and getting quality help is also difficult. I also am a big proponent of the DIY and learning. It serves to make boating more accessible to average people..like me. It really saddens me when I see people struggle with boat repairs and turn to mechanics and technicians that often are not qualified themselves and maybe even make the problem worse. These types of videos are important and serve a great purpose. Thanks much.
Thank you.
That reminds me of a cruiser in Panama who made money working on other cruisers engines. But when he had a problem with his own engine he would came to me for advice.
Bravo Zulu - well done well presented. Keep the series going. For me, this was a great refresher.
Thanks Michael
Thank you thank you thank you Clark. What a great tutorial and I took notes! I am looking forward to the next lesson! Everyone will benefit from this well thought out instruction.
You're very welcome Craig.
I just filmed the second episode minutes ago
Thanks Sooo much.. You guys are the BEST TEACHERS for all things Boats!
You're very welcome
Grate information to know even if you don't have a boat.
Thank you.
Thanks Steve
Terrific job! Wasn't intimidated at all for even a moment. Please continue to make this valuable contribution for so many people.
Thanks
Clark, this is great! One of my greatest cruising fears is running out of power. I need to learn the basics and how it all works.
Great teacher. Loved the lightening rod video. Very knowledgeable man.
Thanks Johnathan
I am installing Shore power and battery charging to my yacht. my instinct was to install the 240v consumer unit close to the 12v ships batteries. as a result of the knowledge from this video, I know to use the shortest 12v wiring length and longer mains wiring, and where a battery charger could supply 8 amps max, maybe to use a bigger gauge wire e.g., 16.5 amp wiring. I must keep insulation away from oils...
so an essential video delivered in an interesting way by giving real practical examples. thanks very much! David 😊
You're welcome David. Glad it helped
Really looking forward to this series as I have some significant electrical projects ahead :-)
That was the most amazing, easy to understand, explanation of a 12V DC system I have ever come across. The little quiz at the end was perfect. There's a reason I subscribed to you all those so many years ago. This week I close on my first cruising boat, which naturally has a few electrical issues. Once again you have inspired and instructed me. Thank you sir! (and thanks to Emily for all the filming and editing!)
Thanks Mike. Will we be seeing you out here soon?
@@EmilyAndClark Most likely not in your current neck of the beaches for a while yet. I plan on Florida this winter bouncing around the gulf and keys, then the east coast next summer. Hopefully after that I'll be able to start doing the Bahamas. All depends on my wife :)
I'm looking to buy a sailboat and want to learn more about the electricity on the boat. Looking forward to take part of this series. Thank you very much for the content!
You're welcome David
Thanks for all the effort you put into these videos. I am just refitting an older boat and so far the electrics is the spanner in the ointment (to mix metaphors madly) . Most appreciated.
Glad to help
The equation really you is for the power loss in the cable. P = IV = I^2R. So if the current is 8A and the resistance of the cable is 0.0972 Ohms the power loss in the cable is (8 Amps)^2 * 0.0972 Ohms = 6.221 Watts.
It is actually more efficient for a fridge to be on all the time with a lower power consumption just keeping the fridge at the correct temperature than to keep switching on and off with a higher power consumption. So dropping the voltage to the fridge can make the fridge more efficient (so long as you don't drop the voltage by creating heat in a cable).
Didn't want to get into a second equation in the first video. One must choose their battles.
And modern compressors run off a brushless three phase DC driver. So lower voltage doesn't slow it down it just makes it draw more current.
But the power equation would have been the "right" way to express this, I agree.
@@EmilyAndClark Thanks, I didn't know that about fridges.
Great serie in becoming, Clark! I have just starting rewiring my Sonic 23 to get rid of the boat gremlins, and this will be of great help!
Thanks Mathieu. Hope it goes well
I learned that triangle in my first year apprenticeship for heavy duty mechanics with Cat , 1978 awesome handy for
Troubleshooting
you guys rock!! been refitting a sailboat and using ALL of your content as reference!!
Glad to help Pedro
Loved your electrical tutorial Clark. Well done.
Thanks Sam
Really appreciate the accessibility of this video. Have wrestled with a lot of these concepts for a long time and feel like I am finally getting it thanks to this video! Thank you!
Good to hear.
With stuff like this it's hard to choose what level to present at
In person I watch the other person's eyes. Camera doesn't help me know if viewers are following.
Thanks for taking the time to produce such wonderful videos. I have used a lot of valuable info you have given....Thanks!
You're welcome Howard
Thanks for doing this Clark. It is appreciated! I am going to show this to the kids.
I appreciate that. I hope they enjoy it.
Thank you!! Im looking forward to the rest of the series. This was extremely helpful and done in a way that makes it easy to understand and learn, without feeling like i had to already be an electrician :)
You're welcome Amy
Yes Clark keep doing videos like these! Much of this stuff I already understand (or think I do). I have corrected some beliefs I had by just always getting more information from different sources.
Thanks Jeff
Awesome job covering the basics!
Thanks Shane
Hey thanks. I kinda knew this but the basics of how they relate and what they actually mean to a boat's circuits was an inspiration moment for me.
Anyway. My knew mantra is below.
push = flow x impedance V
voltage = current x resistance %. %
Volts = Amps x OHMs I * R
