Dean, They are rated at 30amps at 12 volts, I think they will handle a lot more amps than wll be needed at 24.

Re: Is there a valve for the water intake for the washing machine?
Thanks Danny and Bill. I'll look under the stove, don't think I have ever been in there. Are the piping to the sinks all PEX fittings? Anybody know the size of the fittings? Kent SM243 Kristy On Jul 12, 2020 2:30 PM, Danny and Yvonne SIMMS <simms@...> wrote:

Re: New Thread on A54 fridge pumps (ATTN: OLIVER Vela Nautica)
Porter,
I like your thinking re BP analogy. If we take that further... as we can measure arterial flow with Doppler ultrasound techniques, we could use a simple flow meter installed beside the pump to monitor flow rate on an ongoing basis. I love how this thread has meandered from hydraulics and electrics through thermodynamics and medicine. All relevant and all interesting! Cheers, Dean SY Stella A54-154 Sent from my iPhone X |

Re: New Thread on A54 fridge pumps (ATTN: OLIVER Vela Nautica)
Bill,
That's a nicely packaged set. I like the fixed leads which makes Porter's task easier. I am 99.9% certain that they will work just fine as you describe. The 0.1% risk: I could not find any documented specifications indicating that they are rated for switching 24V. Maybe you've seen that somewhere? Cheers Dean Sent from my iPhone X |

Stove igniter replacement
I previously had a source for the exact replacement of the igniter for Eno stoves needing 6 outlets (4 burners + 2 oven burners). If you are adventurous and want to try something with little risk, let me know if this will work: https://www.ebay.com/itm/Universal-BBQ-Gas-Grill-6-Outlet-Spark-Generator-Push-Button-Igniter-AA-Battery-/153027190899 It ships from Hong Kong and is only about $13.60 delivered in the US.

A 55 # 9 : Chargeing and mastershunts

Can anyone advise why there are two 500A Mastershunts installed at the outset.
We see that only one Mastershunt is configured and visible on the monitor. The second does not appear to be visible |

Re: Is there a valve for the water intake for the washing machine?
Kent, I purposefully said, "Later model SM2ks had the following (photo from the Users Manual)" I have no idea when the cut-off valve was added by Amel, but I have seen some SMs that did not have one. Bill

Re: New Thread on A54 fridge pumps (ATTN: OLIVER Vela Nautica)
Porter, According to Frigoboat, the pump selected should move at least 6 liters/min. A 24-volt pump rated at 12 liters/min. running half speed on 12 volts will pump about 6 liters/min. I am not the electrical expert that Dean Gillis is, but I will try to answer your question. In this schematic, the relay has a 12-volt coil that activates an internal switch. The switch could switch either 12 volts or 24 volts. In the schematic, you will note that only the positive is switched. Dean, feel free to edit or correct. That relay in the schematic is a very ordinary "Bosch style" normally open 4 pin relay which uses 2 pins (85 & 86) to activate the coil, meaning when 12 volt positive is connected to 85 and 12 volt negative is connected to 86, a switch is closed between 2 pins (30 & 87). There are 2 types of 4 pin relay available; normally open or normally closed. A normally open relay will switch power ON for a circuit when the coil is activated. A normally closed relay will switch power OFF for a circuit when the coil is activated. You want a normally open relay for this project. To further confuse, there are 5 pin relays which allow either normally open or normally closed depending on whether you use 87 (normally open) or the fifth pin 87a (normally closed). This is a package of 6 4-pin relays with sockets and wire: https://www.amazon.com/PACK-Pin-SPST-Relay-Harness/dp/B07X1R18QS/ref=sr_1_1_sspa?dchild=1&keywords=Relay+4+Pin&qid=1594563018&s=automotive&sr=1-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExVzkxWjQ5OTBBMjcyJmVuY3J5cHRlZElkPUEwNjYyMDMxMlA0MU85WDRTVURSNCZlbmNyeXB0ZWRBZElkPUEwNjEwNTc4OUdOQVJGUVQzVDdPJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==

Re: Is there a valve for the water intake for the washing machine?
Along the same lines, I had a sink faucet fail last year, and had no way to shut water off to one faucet. On my list is to put a shutoff valve on every faucet. I didn't know there was a shutoff valve for the washer. Gotta find that. Kent Sm243 Kristy On Jul 11, 2020 1:23 PM, Willem Kroes <kavanga@...> wrote: Thank you Bill, |

Re: New Thread on A54 fridge pumps (ATTN: OLIVER Vela Nautica)
Hi Scott,
Yes, it does seem a bit counter-intuitive that warmish water is more efficient than cold water. Here is a paraphrase from my system's technical manual that may help in understanding it. The reason (that 90F sea water is optimum) is that in the refrigeration cycle, after the high pressure liquid refrigerant has passed through the expansion valve and gotten cold by converting to a gas, then passed through the cooling coil and taken on the heat of the refrigerated area and then gone back through the compressor, it is about 140F and only needs to be cooled to about 120F to condense back to liquid and repeat the cycle. Thus 80-90F cooling water is all that's needed. In colder water the liquid refrigerant is too cold and is stored in the condenser and the system operates with a much lower suction pressure as the pressure difference across the expansion valve is reduced. This will substantially decrease the capacity of the system and increase the running time. That same manual offers corrective solutions for operating in cold open ocean water by using a gate valve or a water by-pass to restrict the flow of too cold water and get the drier and receiver temperature up to about 95F. From just an everyday non-technical vantage point, consider that the marine market is absolutely insignificant to the global refrigeration market (no special refrigerants, etc. - there is no such thing as "marine refrigeration" outside of the marketing department). Nobody has cold water cooling - Eskimos don't need it! Household refrigerator cooling coils have ambient temps in the 70's or 80's or more (room temp). Apartments and buildings have water source cooling tower ambient temps in the 80's and 90's (or 100's here in Florida) and, therefore, cooling water temps are the same. Those systems are, in fact, at maximum efficiency because they are providing cooling at the condensing temperature of the refrigerant - 80 to 90 ish, depending on the refrigerant. And, oh by the way, I just Googled Windy.com, clicked on the water temperature, and from 20 S to 20 N, including the entire Caribbean, the water is in the 80's. At my dock in Florida it's 92F. My A/C and refrigerator love it! As do all those cruisers who used to be there before Covid. I would assert that no marine refrigeration system is designed to operate in extra-tropical ocean cold water temperatures - unless it has a gate valve or by-pass for cold water use. That pump life has been seen to be inversely correlated to ambient temperature is perfectly understandable. It's not the cold cooling water, it's the cool ambient temperature. The cold cooling water is actually increasing the running time and fighting against the cool ambient temperature that is decreasing the running time. It would be fun to experiment with a system with a gate valve or by-pass valve in a cold place. Run the system with 55 degree water for a few days and log the run times. Then throttle down the valve to get 95 degree water for a few days and log that. Then check Oliver's fancy logging system and see what it shows. Dollars to donuts the warm water will see less pump usage. Fun topic for a locked down Covid evening, thanks for initiating the discussion, Cheers, Craig |

Re: Hardtop for Amel 54
Hi Mohammed, Thank you for the info, Unfortunately I will not be going to the US for some time. My thoughts are that we are going to be here for some time. I really like the hardtop on Caduceus, I will look into this, will need a stainless steel welder, a fibre glass moulder and a canvas/sail maker. Could be a challenge here in Le Marin! By that I mean that getting work done is a challenge and slow, took 3 months to get 4 brackets made for my new lift up windscreens, The early 54's only had one hydraulic lift arm on each lift up screens at 300N, I am changing to two hydraulic lift arms per screen as per your 54 at 170N each. If I was still in Greece I would be able to find these workers, Preveza has a young chap, very good at stainless work. The hardtop on Ruedi and Sabina's Amel 54 might be insulated. Contact Ruedi and he will give you all the info. It looks very well made. Very Best Barry and Penny "SV Lady Penelope II" Amel 54. #17 Sainte Anne anchorage Martinique

Hi Scott,
Thank you for the photo. I am going to see them on Wednesday when everything reopens here after this holiday weekend. I do hope that your price is not correct. My current Bimini is an all cover, 5 bow frame with Sunbrella, like the hardtop made for Caduceus Amel 54. #56.
