Hey Richard, I think we lost you there, is everything ok? Hoping so and that your business is doing well and keeping you busy. Looks like you have a pretty good thing going here with the videos w/ over 15k subscribers and over 70k views on this video alone. Looks like several people were really appreciating the unique content. Hope everything is ok and that you find the time to come back to video making soon. I know content production can be extremely time consuming. Thanks for what you have done so far, it's awesome!

[@tomm1968]

Best boat electrical videos I've seen yet. Very clear, easy to understand instructions on the practical aspects of wiring methods. Most electrical vids are all about wire and fuse sizing, and that sort of stuff. No one ever shows you how to put it together on the boat, and why you do it that way. Great stuff. Can't wait for Episode 4!

[@jonnychapman2010]

This bilge pump setup seems as though the master switch would cut power to both bilge pumps? Would you not want at least one wired more directly to the battery so that when you turn off the power at the main switch, the bilge pumps can still operate - to pump out rain water whilst on a mooring etc? Great video and really helpful!

[@genglandoh]

On my sailboat I wire my safety items the following way 1. Automatic bilge pump thru the special auto Manual switch then to the batteries 2. VHF bypasses the switch panel but is not wired directly to the batteries. This way when I leave the boat I turn off the master switch cutting power to everything except the automatic bilge pump. To turn on the VHF radio I turn on the master switch then the switch on the VHF Radio.. This way if the switch panel has a problem I can still use the radio.

[@davidsaucedo3]

[@whitestarhorros3374]

Thank you for your videos. I have been working on my 1972 Tollycraft 40, I decided to rewire it as the wiring was, let's say interestingly badly maintained. I thought it would be "fun" to just rewire, lol. In 1972 there really was no off-grid type of wiring so everything was wired for a genset or dc and shore power. Well I wanted to simplify and upgrade to new wire codes, lots of fun so far. I have taken this Tollycraft 40 to a new level of totally off-grid self sustained life. Watching your videos are helping me understand the dc side of wiring in its simplest form, as i do have extensive knowledge in the ac side from my off-grid projects. Awesome videos thanks again. 👍

[@BoatFittings]

Hi thanks for your comment - glad to be of help! Richard

[@JSGregg]

I've never wired a boat, I just find wiring interesting. Looks like once you've done a couple circuits, it becomes pretty repetitive. Positive -> Fuse/Breaker -> Switch -> Device -> Negative. Once you grasp that, you can easily add in whatever you need. One thing to consider is using a relay to switch higher current loads like motors, then a toggle/rocker switch to activate the relay. Saves your switch contacts a bit and may keep you from doing long runs of thick wire. Especially for motors, which are electrically spikey and noisy, a solid state relay may be the most reliable (the name brand ones), as opposed to running it through a toggle/rocker.

I’ve got a new (old) boat and redoing a lot of the wiring and although there aren’t many standards for marine wiring, nearly all of them state “do not rely on soldering alone for wiring connections”. I’m opting to crimp and then use waterproof shrink connectors. Where would you place a master fuse (50A) in your wiring model?

Glad to see this episode is out! I can't wait for ep4! Maybe a "relays, cables and fuses" related video would be nice, perhaps? You could explain why would you need relays, when would you want them, how to size cables and fuses for the appropriate circuit... I am in the process of building from scratch my dream boat. The boat I bought, it had no mechanics in it, I bought the mechanics from a separate boat and got to merge both together, so I also need to add pumps, gauges, etc and I'd like to do a proper job at it with properly sized fuses, relays where needed, etc...)

[@jeffdege4786]

Everything you've done so far is switched - as in turned off if the master switch is turned off. There are circuits on the boat that should still be powered if the master switch is turned off - automatic bilge pumps being one example. Or, at least, if your boat is left in the water when unattended, the bilge pump should not be wired through the master switch (though you would want it to have its own switch).

[@gogetnic]

Totally. I was looking for this comment. That boat is sinking.

[@philipkenneth24]

Well done sir. Excellent explanation and demonstration

[@brentoneel4094]

[@danielcookeb90]

great video! Like Einstein said, make it as simple as possible, but no simpler! Brilliant! Well done Richard. I'm wondering at the cycles these automatic elecrtonic bilge pumps are rated for? What are their Time To Failure numbers for their internal parts. And if used as designed (to actually test every 2&1/2 mins) 24-7-365 days a year, At a 2.5 minute test cycle, that's over 109,000 cycles every year????? after 2&1/2 years that's over a quarter of a million cycles? I think your inclusion of the float switch and manual pump is far safer, plus the automatic pumps with the built in float!

[@GioBen68]

Excellent tutorial! Thank you 🙏🏼 one question though : if you switch off the battery and remove the key, the automatic bilge pump will not work if one day there is water while you are not on board, correct? Shouldn’t the bilge pump be directly wired to the battery?

Richard, these are so very helpful! I have a 78 Ericson 34 and am having to troubleshoot wiring. My 12v panels (have 2), no longer receive power from the battery or they are not working anyway. We tested the batteries (have two), tested continuity to our switcher. I’ve cleaned the connections of corrosion, etc but still no power. And, these panels worked a few weeks ago. Only thing I changed is I added a Smart Plug shore power hookup for my AC power. Also now having a “Reverse Polarity” warning to boot!! Any tips? Again, we’ll done on these videos, very helpful for a new sailboat owner!!

[@BoatFittings]

Hi thanks for your kind comment. With your current problem my first suggestion would be to temporarily disconnect the new 'Smart Plug' to see if that resolves the problem - if that is the case then you can say that it looks like the problem was introduced with the Smart Plug, if that does not resolve the problem it is a case of working from the battery 'outwards'.

[@mikejohnson5157]

Question, it seems that the positive wire for the 2nd bilge pump goes thru the fuse panel. Wouldn't you wire the auto wire direct? The auto feature will not work unless that switch is on, meaning the isolator must be on as well. Forgive me if I missed something.

[@Turaelin]

Thank you! As someone who has been electrically challenged for his whole life, I thank you. It is simple wiring that I just can't "see" in my head. This series is finally making sense. I don't need the theory, I need hands-on, step-by-step how-to's that make real-world sense to me. I do wish you had walked us through each step, especially the switch, how it was wired and why... (and may I ask why ALL "power" or "hot" wires are not RED??? IMHO if a wire carries 'live current', it should be RED...) I am working my way slowly into the existing wiring and my need to repair / update / add / remove systems as I upgrade and refit our sailboat in preparation to liveaboard and cruise. I am currently trying to wire up a secondary diesel fuel pump (Edelbrock 38GHP #17302) for my DIY dual Racor 500FG Diesel Polishing system... and I will admit to being a little stumped trying to wire up a 2 way, 3 pole toggle switch... (I have since decided to use a 30A 2 pole Breaker Switch instead...) PLEASE keep going, and please keep it at a Boat Wiring for Dummies level!! =] CJ&JD Blackwell SV Rocinante 95' Gozzard 44 MK1A

[@BoatFittings]

[@lildeena1]

Sorry if this is a dumb question. I don't have bus bars and my auto bilge has been disconnected for years. Can I just wire up a system completely isolated from everything else and keep the 3 way switch mounted near the stern near the battery compartment and pump? and run my pos / neg direct to the battery?

[@timhodges9763]

Richard I can't afford nothing but an aluminium John boat. I've been wiring it for lights. Running lights and a couple spot lights for night fishing. I built a wooden box to attach my switch panel. Was planning to run switch panel directly to the battery. Then run positive wires from lights to switches and negative wires to a buz bar then buz bar to negative post on the battery. Does that sound workable. Oh my switch panel has resetable circuit breakers. Thank you for your attention

[@scotturban2046]

Great video series! Just one question...If I run a bilge with the float switch how can I wire to allow the bilge/float to operate when the main switch is off?

[@BoatFittings]

Hi thanks for your question, it is possible to wire the bilge pump system direct to the battery via a separate circuit to achieve this. Kind regards, Richard

[@lambertodigioia5084]

Thank you SO much for these amazing how-to videos. In this one (part 3), you refer to a manual override option for the first bilge pump. Do you recommend resorting to a separate 3 positions (on/off/auto) switch like the one used for the second pump, or to use the panel (on/off) switch for manual override and have the auto-switch bypassing the panel (to stay always on on auto)? Thanks

[@dziubo1]

Awesome video! One question, that wasn't really explained. Connecting negative from automatic bilge pump and negative togeather wasn't necessary, right? We could separatly connect it to the bus, as far as I understand.

[@BoatFittings]

Hi thanks for your comment. Yes if I understand your question correctly, both wires could have been brought to the busbar to achieve the same effect. Kind regards, Richard

[@francismcdermott459]

Why soldier rather than crimp, or, even better, crimp first and then solder? If the bilge pumps are switched, then every time you leave the boat switched off, the bilge is unprotected from flooding. Thank you for painstaking efforts in providing this collection.

[@BoatFittings]

Hi thanks for your comments. I just find soldering easy to do, and crimping not always so easy - depending on what equipment and terminals you have. As I have mentioned a few times I have not had any problems with soldered joints, but have had some with crimps. I understand that some people would prefer to have a 'permantly-on' circuit for their automatic bilge pump, and agree that there is a logic to this. In a future video I will include this type of wiring. In any case though, my preference is to have a way of easilily turning off ALL electrics in the boat, from the point of view of not having to worry about the possibility of electrical mal-function while away from the boat - I think this is a matter of choice and priority (dry bilge vs electrical safety or run-down battery). Kind regards, Richard

[@cward8110]

for the auto bilge pump, utilizing the 3way switch for auto/off/manual, is it necessary to utilize the main switch panel as well or could you just bypass and wire the 3-way switch directly to a power and negative terminals...the use of both switches for the one pump seems redundant

[@JohnCornellier]

Fantastic videos, can't wait for more. Question though: in 2023 why are we still using fuses rather than breakers? Are fuses just cheaper? Or is there some technical difference?

[@BoatFittings]

Hi John, Thanks that seems like a good question. I happened to have the 'fuse-type' handy to make the video, I beleive you can buy the equivalent panel with breakers, I guess it is a cost vs convenience balance. Richard

[@pifprime]

May I ask why not breakers instead of fuses? Breakers you can reset on the spot?

[@BoatFittings]

Hi many thanks for your kind comment. Kind regards, Richard

[@johnk9654]

Thank you so much for these videos. Can't wait for the next one. Two questions though. 1. Would you want the auto bilge pump wired before the master on so it can run while away from boat without other power on? 2. What is the make / model of that dc power supply. What amp model should I be looking for? I need to get one. Thanks.

[@0to100Adventure]

Part 4 please ❤

[@1spencerneal]

Great videos. Very useful and reassuring, especially as I recognise the switch panels and busbars. Question, why does my LED cabin light dim when the bilge pump's test routine kicks in. If I switch the light off and then back on, it returns to full brightness. The light works fine, even when the pump is actively pumping. Is there some way to fix/prevent this? Many thanks.

[@BoatFittings]

Hi thanks for your comment. That's an interesting problem - a bit confusing. It sounds like the action of the bilge pump is causing a voltage drop in the lighting circuit, which the LED is not very good and handling. Without further knowledge of how your circuits are laid out, I can only suggest to look into separating the bilge pump wiring from the lighting wiring, if that makes sense? The other thing you can do is to check the voltage at the battery to see if it is up to scratch. Kind regards, Richard

[@martinhillersweden]

Nice! Just a suggestion. It's better to have the bilge pump connected directly to the battery. Otherwise your pumps won't work when you're away and you get a leak... 😢

[@BoatFittings]

Hi thanks for your comment. I think you make a valid point, and there are some benefits to what you suggest. Worst-case scenario you choose whether to prioritise a dry bilge vs drained battery potential. Kind regards, Richard

[@smithed3448]

I think it would have been a good idea to to have mentioned the fuses for each switch and fuse function.

[@BoatFittings]

Hi thanks for you comment. I am planning out part 4 now, so hopefully not too long away. Kind regards, Richard

[@AlistairBancroft-b3j]

Can I ask why you wire the BILGE pumps through the switch panel and the battery isolator? This is the first thing I test on a survey and always get told the isolator is it won't work. So the boat only takes on water when you are on board and the isolator is on? This should be wired directly from the battery to your BILGE PUMP fused manual/ auto switch panel. Hope this helps Alistair

[@BoatFittings]

Hi Alistair, thanks for you question / comment. I take your point / recommendation / opinion - though I think there is some merit to being able to easily isolate ALL electrics in one master switch. In my opinion if I was going to leave my boat for a long time I'm uncomfortable having a device of any kind (like a pump) permanently on, in case of malfunction. Kind regards, Richard

Hi thanks for your question. You do not specifically need a seaflo switch. The important thing is the you achieve the equivalent functionality. One of the positives can run through a switch to the battery for manual operation. The other positive can run through a separate switch to the battery to give automatic operation. Both positives want to run through switches though. Kind regards, Richard
