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.
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.
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 UA-cam, 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.
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!
@@icarumba5 I agree with this. Great explanations and just a pleasure to watch. I have an excel spreadsheet with conversions on wire with the resistance and surface area and oms calculations and lost volts because of the inspiration from this video
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.
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!
I just wanted to thank you for this series. I did not know even what a volt meant a month ago, however after watching some of your videos I finished installing a solar system on my boat today.
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 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.
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
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!

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
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. .. .
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!
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
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.
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.
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.....
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.
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!
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. 👍
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.
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!
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. 🌞🌴⛵️
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.
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.
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.
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.
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.
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.
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
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.
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!!
Hi, @Emily & Clark's Adventure ! Congratulations and thanks for explain and sharing, with simple words, your knowledge and experience. Fair winds and seas!
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.
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.
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.
Pretty cool Clark! Where are Kirchhoff''s laws and Maxwell's equations? Just kidding. I am sure this series will help people. Hope it goes well, and many views.
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!)
@@Clarks-Adventure 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 :)
Hi guys. Only just found you on UA-cam 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.

Got your hint
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.

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 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

You're very welcome, Matt
Good stuff Clark! Keep it coming
Well done! I used to do small boat electrics before Covid. I will share this with my ex customers.
Thank you
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.
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
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
Great teacher. Loved the lightening rod video. Very knowledgeable man.
Thanks Johnathan
Looking forward to the more advance, complete series !!! Thank you !!
It might take a while to get there. Lots of viewers seem to like taking small steps.
@@Clarks-Adventure No hurries, I will follow the steps. Happy to recommend your videos, grateful for the quality content.
Thank you for sending out the links Agustin
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.
Bravo Zulu - well done well presented. Keep the series going. For me, this was a great refresher.
Thanks Michael
Awesome job covering the basics!
Thanks Shane
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.
Thanks, please continue the series!
You're welcome
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.
Definitely enjoy your deep dives. You video on VHF radios and antennas was really informative and really made things make sense.
Thanks Nathan
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.

No, you’re not the only one, there are too few.
Thank you very much, The black art and mystery of electricity is being solved.
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
Thanks for clarifying. Excellent video!
Your welcome Carl
You make a complex subject matter very easy to understand! Thank you kindly! Take Care
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
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.
Awesome. Great intro guys. Taking notes as I go. Thanks!
Grate information to know even if you don't have a boat.
Thank you.
Thanks Steve
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
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
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
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 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.
Outstanding as usual and I shall look forward to the next one. Well done for making it easy to understand.
Thanks Mark
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.
Thank you for sharing with us.
Thank you. I am very much looking forward to the coming parts.
You're welcome Michael
Pretty cool Clark! Where are Kirchhoff''s laws and Maxwell's equations? Just kidding. I am sure this series will help people. Hope it goes well, and many views.
Small steps.
Please keep going with this. It's exactly what I need. Thanks a lot.
You're welcome
Both of you have excellent teaching videos. Thank you so much for sharing.
Thank you
Superlative explanation, with one caveat: Many boats have both DC and AC circuits.
Yes. I guess we could get to that.
Thank you for this. Can't wait for it to progress.
You're very welcome
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?
@@Clarks-Adventure 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 :)
Thank you for making this series.
You're welcome Torsten
Thanks Sooo much.. You guys are the BEST TEACHERS for all things Boats!
You're very welcome
Hi guys. Only just found you on UA-cam 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.
Perfect! Getting ready to buy a boat and want to learn everything so I can fix myself. Thank you!
you guys rock!! been refitting a sailboat and using ALL of your content as reference!!
Glad to help Pedro
