What you NEED to know about Boat Electrical (Part 1)

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.

[@johnny_hammer]

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

[@edgarmuller6652]

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.

[@icarumba5]

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!

[@EmilyAndClark]

Ahhh.

[@lpatrickdickerson9807]

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 KZbin, 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.

[@j.brianbobiak12]

I do electrical engineering for a living and Clark has done an excellent job teaching in this video. He's a natural! GREAT JOB!

[@EmilyAndClark]

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.

[@michaelsweeney4638]

Thank you so much. I am absorbing this like a sponge!

[@JT-sr2pl]

This is excellent. Thought it was too basic for me, then quickly realised I was wrong.

[@EmilyAndClark]

We will go deeper.

[@realpetrovsky]

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!

[@cseguin]

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.

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!

[@davidgrowse2041]

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).

[@charle64]

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

I haven’t even watched yet and I’m so excited to find this. Thank you, skipper!

[@EmilyAndClark]

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.

[@scottkrebs586]

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!

[@jonathanwetherell3609]

Cars and boats, most of the problems are corrosion or a broken wire.

[@t1n4444]

@@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.

[@braithmiller]

Constant equipment and especially diesel issue. Many times all I do is fastidiously clean up every contact in a circuit.

[@acevedolc]

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.

[@EmilyAndClark]

Thanks Melanie. So glad you liked it.

[@allanpierce9700]

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. .. .

[@charlesbechtel9976]

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.

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.....

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.

[@dustman96]

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.

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.

Thanks Tyson. When was that? I think I learned this before the idea got out.

[@Brandonsniffskids]

I was an apprentice 2007-2011 in mountain states line constructors. We call it ohms law.

[@Brandonsniffskids]

It may not have had the triangle but was expressed as V I R

[@EmilyAndClark]

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.

[@gregstark9885]

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.

[@EmilyAndClark]

Episode two is about wire. Just filmed it yesterday.

[@user-eo4cd6ql6p]

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!

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.

[@francleo2002]

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!!

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.

[@JeremyWilliamsTx]

Good stuff Clark! Keep it coming

[@tommussington8330]

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.

[@caparn100]

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).

[@EmilyAndClark]

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.

[@caparn100]

[@davidpotter4909]

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 😊

Great video, Clark! Clear and comprehensive. Thanks!

Thank you

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

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.

Outstanding as usual and I shall look forward to the next one. Well done for making it easy to understand.

Love these deep dives!

Thanks Clark for doing this series. I was much more in practice when I was young, so reviewing these things now when I am working on my new boat's electrical systems is super helpful...especially since as I have gotten older and not used certain equations so much, I have forgotten many of them. Keep up the good work.

You're welcome

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

[@blackduck7851]

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
