Re: Miele Microwave on A55 not working

 

It is likely something serious, but I had the same issue with my Amel installed microwave.

I opened it up getting the non-tamper screws out and discovered that when some of the internal spade connections were touched it came to life. I disconnected all of the connections, brushed-on some CorrosionX, reassembled it, and it lasted for years until we replaced it with one with more features.

I know this sounds like a commercial for CorrosionX, but it's a true life example of micro-corrosion and solutions while living aboard with salt air, and CorrosionX.

I can’t help with the exact model but I’ve fixed a few microwaves in my day and it’s usually one of two causes, both easy for DYI although you do need to be very careful to ensure it isn’t plugged in and you discharge the large capacitor before poking around in there as it can carry a lethal charge.  Most microwaves have a large internal fuse (15A usually) that can trip (often if someone accidentally put metal inside). The other is that the magnetrons fail. They are easy to replace as well (usually just a few wires). The other thing to check would be the door switch but it doesn’t sound like that as it failed mid cooking. Good luck!

Hi  Colin

I still love my SM.Ocean Pearl but if I suggested to Yvonne  a 50 she would say yes yes yes. But for me the systems on the SM, the ketch rig, the ease of sail control and the supreme sailing controlability in any conditions and the sea kindliness all combine to hold me.

I do hope that Amel sees that video and does something about strengthening those rudders, and also considers the prop shaft support issue too.

They told me that the target for the 50 was existing Amel owners who had done their major passages and wanted a new boat with all the great features of Amel but more suited for inshore sailing.

Who am I to argue with that. There are hundreds of us out there.

It seems Amel changed the construction of the rudder(s) quite drastically. But they are not alone, Hallberg Rassy is doing the very same thing. The added beam at the stern of the boat makes this inevitable.
From my personal point of view. I think everything under the waterline must be as close to bomb proof as you can realistically make it. So these modern hull shapes with twin rudders are posing a devils dilemma in my opinion.
I found it also a bit uncomfortable looking at the size of the P-bracket that guides the propellor-shaft. I would have preferred a upside-down V-shape for that thing. This setup seems very fragile as well and begging for bent propellor-shafts

I’m aware that these wide bottoms do give you nice sail performance but I’m not so sure if this new design is not conflicting with the prime directive of what Amel stands for.

I guess time will tell…

Re: Windlass ans BT batteries

Mike Longcor (SV Trilogy)
 

Hello,

The Santorin may be different but the BT and windlass motors on our Super Maramu are 24V while engine start is 12V.

Is your set up like this or is everything 12V?

We have a 24V alternator (in addition to the 12V alternator) that provides charging to the service batteries while engine is running. Maybe this is your best option? The lithiums will have more capacity and do a better job of supplying the high power required for BT and windlass compared to a lead acid anyway - if that's what your start battery is.

Cheers,

I found the switch it is like the one behind the DC panel in the galley. Really big switches that take up space I will be swapping these out for much smaller ones and labeling them for the next owner. Way to much time spent identifying wires.

On WASABI we have the same setup, except that there is a separate “Permanent ON/OFF” Switch under the converter (see picture).

I suppose you have another ON/OFF configuration on the Permanent and therefore they bridged the +0 on input and output.

Probably GARULFO do not have a ON/OFF Switch for the Converter Input and therefore the bridge makes your converter permanent as permanent 😉

The other 2 converter are just switched on when you push the green “INSTRUMENTS” button at the chart table next to the window.

On GARULFO, and I suspect on other A54s and maybe SM, there are three 24VDC to 12VDC converters, marked “permanent”, “hydra/iscan v90” and “VHF icom”.

 

Of those, only the “permanent” one has the input +0V and the output +0V posts connected. 

 

Does anyone know why that is?

Why shouldn’t the other 2 be the same?

Hi Mohammad,

I have altered the 230V switch panel so now all groups are supplied by the inverter. It does mean you need to think about the things you switch on simultaneously but with the original solution that was the case as well. As I replaced the A/C units with inverter units they do not suffer from huge startup currents anymore, also they use less power..
Two groups are excluded from the inverter, as you can guess, both battery chargers are exempt.
The 40A charger can be used only if there is shore or generator power. Activating the 100A charger (when connected to shore power) will cause the Mass Combi to be disconnected from the shore power and start inverting. This is effectively the 60Hz to 50Hz conversion. So now we can run the clothes-washer in Saint Martin without using the generator.

Enclosed is the Schematic Diagram of the 230V side and a picture that shows the new circuit breaker for the Combi Mass.

Re: 24VDC to 12VDC converters: 0V connections

Sv Garulfo
 

Thanks Arno,

The only equipment officially connected to the permanent converter is the car radio (for station preset memory retention if I understood correctly). Maybe that doesn’t like floating voltage for some reason...

The vhf is definitely transmission equipment so I guess the theory applies there.

The B&G simnet network (for the analog displays) is an N2k implementation, powered in 12V, so again the theory applies I guess.

My guess is that these are isolated converters. So the input and output are not galvanically connected. This is typically required for radio transmitter equipment to prevent ground loops. This is where you can get all kinds of funny effects because of impedances of equipement relative to the minus/ground lead. Another example is NEMA-2000 supply that (officially) requires a isolated ground as well, so for this you need to use an isolated converter.

It may be they found a problem with some devices not having a ground connected to the battery ground and therefore had to connect the two 0V lines together.

Two groups are excluded from the inverter, as you can guess, both battery chargers are exempt.
The 40A charger can be used only if there is shore or generator power. Activating the 100A charger (when connected to shore power) will cause the Mass Combi to be disconnected from the shore power and start inverting. This is effectively the 60Hz to 50Hz conversion. So now we can run the clothes-washer in Saint Martin without using the generator.

Enclosed is the Schematic Diagram of the 230V side and a picture that shows the new circuit breaker for the Combi Mass.

Hi Nick et al. I agree with you. I was considering a move from my SM to a 54. I would never never consider one with the sort of complexity many 54 owners are installing. These are boats, not luxury condos. You don't take a condo to remote locations nor cross oceans in one. The condo will never experience the harsh marine environment attacking its electrical connections and electronic systems.

But then I am a sailor through and through, I guess there must be others out there too.

Hi Danny,

I’m not sure if I agree with you on this. The SM and A54 are very similar in complexity of the electrics when they left the Amel Yard.

There are plenty of SM owners that also add a lot of complexity to their boat.
I did not add complexity just for the fun of it. I did it because adding functionality or replacing broken functionality adds complexity most of the times. A good example where this is not true is when you change form NMEA0183 to NEMA2000. This actually makes things more easy as you need less cable to connect stuff. 
Adding Solar and/or Lithium will add complexity. Having more systems also brings in more need for supervising/monitoring equipment to spot upcoming problems.
My goal with our A54 is to keep systems as simple as possible but the reality is the A54 is a highly technical vessel with lots of toys.

My biggest beef with the electrics is that Amel changed several things during production (newer devices came to market) but never updated the user manual or the quite limited circuit-diagrams that are part of the documentation. So I had to reverse engineer several things to understand their workings.
Typically when I change things I make a circuit diagram of the new situation. That helps me as well if I need to look into a system later.

Re: 24VDC to 12VDC converters: 0V connections

My guess is that these are isolated converters. So the input and output are not galvanically connected. This is typically required for radio transmitter equipment to prevent ground loops. This is where you can get all kinds of funny effects because of impedances of equipement relative to the minus/ground lead. Another example is NEMA-2000 supply that (officially) requires a isolated ground as well, so for this you need to use an isolated converter.

It may be they found a problem with some devices not having a ground connected to the battery ground and therefore had to connect the two 0V lines together.

Hi Thomas

 

On WASABI we have the same setup, except that there is a separate “Permanent ON/OFF” Switch under the converter (see picture).

I suppose you have another ON/OFF configuration on the Permanent and therefore they bridged the +0 on input and output.

Probably GARULFO do not have a ON/OFF Switch for the Converter Input and therefore the bridge makes your converter permanent as permanent 😉

The other 2 converter are just switched on when you push the green “INSTRUMENTS” button at the chart table next to the window.

 

Best and fair winds

Betreff: [AmelYachtOwners] 24VDC to 12VDC converters: 0V connections

 

Hi all,

 

On GARULFO, and I suspect on other A54s and maybe SM, there are three 24VDC to 12VDC converters, marked “permanent”, “hydra/iscan v90” and “VHF icom”.

 

Of those, only the “permanent” one has the input +0V and the output +0V posts connected. 

 

Does anyone know why that is?

Why shouldn’t the other 2 be the same?

 

In one pic:

 

 

 

Thanks

 

 

Best,
