Re: converting 24v alternator to ribbed micro v (serpentine)

Dominique Sery
 

Hello,
When I bought my boat in 2017, the broker told me that the Neuville 24 volt 175 amp double V-belt alternators originally installed on the first 54 were recalled by Amel for exchange with the Mastervolt 24 volt 110 amp flat belt alternators with Volvo mounting bracket, due to recurring problems with the belts, misaligned pulleys, mismatched?
Changing the pulleys is worth a try, it will be much cheaper than buying a Mastervolt alternator, the pulley, the Alpha pro regulator, the Volvo mounting bracket (about 2000 euros the whole).
The 54 that I bought ( 54 # 16) benefited from the change supported by Amel, I've been told.
There was no problem with the Supermaramu equipped with Neuville alternators, but the engines were different from the first Amel 54

Ah, Nick you've got me again!
Subtle differences between SM and 54.
Yes clearly a design issue.
Belt manufacturers specify minimum pulley diameters for each section belt and the minimum for B section is generally half again what is specified for A section

Main mast Antennas

Slavko Despotovic
 

There is a piece of cable hanging from the top of the main mast mast. Any idea if Amels have been originally  delivered with two antennas on the main mast? I have one on the main mast that is fine and is for the VHF radio. There is one on mizzen for AIS. The second one on main mast would be for FM/AM radio?

Just update on pump. It is fine after the cleaning. there was a piece of dirt in the end of the line (3cm very solid) above the anchor that I cleaned and system is working fine.

Re: Galley fridge intermittently cooling

Mohammad Shirloo
 

Hi Thomas;

 

An LED bulb will not work. You need an old style LED Diode. These have the two long pins that are usually installed on circuit boards and usually come in a red color. You could have other colors too, which is fine. You can usually find them in electronics stores. Try reducing the RPM to 2000 and see if that helps. If it does, and the compressor starts and stays on and the fridge cools, then your compressor may be getting to the end of its life.

 

We just replaced the compressor under the top load refrigerator in the galley. I think all of the three compressors are the same or very similar.

Thanks Mohammad,

 

Hi tried rigging one of my led saloon lights to the connection points on the controller but it didn’t show anything. I blame my rigging/understanding of the connection points. As an aside, i believe the fan attached to the metal radiator on the compressor to be failed. 

 

The potentiometer is set to 3000 rpm at present. 

 

Did you replace just the compressor part, or also the evaporator? Our issue applies to the Stainless steel unit, which is our primary fridge. 

 

Investigation continues...

Hi Thomas;

 

We had a similar situation last year. The controller on the compressor is equipped with an LED or a connection point that an LED can be connected to, so the unit will give you one of 4 or 5 error codes. I do not remember exactly as it was a while ago and I do not have all of my notes in front of me.

 

There is also a potentiometer (variable resistor) on the board that allows for selection of the compressor RPM. In our case, reducing the RPMs from max RPM of 3500 to 2000, fixed the issue for about a year. After that, the problem reoccurred and our investigation, along with a  trusted dealer in Corfu Greece, led to the conclusion that the compressor had failed an we ended up replacing the entire unit.

 

Lowering the RPMs has the effect of lowering the load on the compressor. So if the compressor is marginal, it will work for a while. The effect of lower RPM on the performance of the refrigerator, is the speed at which it cools the unit down to the desired temperature. Our unit was 11 years old at the time and we felt had provided an expected life for the product. This was the top load refrigerator in the galley that gets a lot of usage.

Hi all,

 

Our fridge evaporator seems to be partially and  intermittently cold. And the compressor runs but stops after a while. It had happened recently that the fridge stopped cooling but after a stop and start, i heard a hissing noise near the evaporator and it worked again for a few weeks. 

 

I searched this forum for contributions and found plenty around refilling the system with cooling gas, amongst other solutions that I will investigate. 

However, I was under the impression that there was a discussion about ice crystals clogging the evaporator circuit and some filter that could be changed. I cannot find that discussion though and may have dreamed it altogether...

 

Any advice on that front?

Hi Alan, 
Yes I know your set up is great, but you are running A section belts whilst the early 54’s were set up for B section.  This is the crux of the problem.
I have an external regulator.
I have had both pulleys off and checked at a machine shop. I have re aligned to perfection, but driving a B section belt around a tight pulley does not work.
I tried A section belts in the old pulleys but they bottom out.
So sticking with the old meant a new big pulley ...$$

Hi Nick,
Whilst I agree serpentine belts are the ultimate for these applications, I would have to say that in 7 years we have had no issues with the twin belt setup on our Yanmar with Leece Neville 175A alternator - and we have an external regulator which means that the alternator works harder than a standard one.
I changed the belts 5 years ago, just because I thought I should, and we had only just noticeable dusting and never broken or worn out a belt.
In my previous experience, belt dusting and short belt life is caused by one or both of two things
1. Pulley misalignment
2, damaged V grooves in either or both pulleys - the groove sides must be absolutely smooth and clean.
and of course, incorrect belt tension.
A recommendation for belts I got from a local belts and transmission supplier, years ago, is to use Dayco / Carlisle raw edged cogged belts. They go around corners better and offer superior grip on the V pulleys than solid belts.
I have been using those belts on this boat and the previous one for  nearly 15 years with no issues ever.
An advantage to using the standard setup, on our boat anyway, is that all 3 belts on the front of the engine are the same size.

Hi Thomas,

Ice crystals would occur if the filling of the system was not done properly. There is a filter in the system that binds any moisture that may be left at filling time. Normally they replace this filter when refilling. Once a system is working properly there is no interference with the atmosphere so moisture cannot enter. If the system is leaking you may see moisture enter the system after so much gas has escaped that at run-time the low pressure side gets below atmospheric pressure (depending on where the leak is). If you still have the original compressors (you can see this by looking at the way the speed control works). The newer units use a rotary switch if I'm correct. If you still run the originals chances are you have a gas leakage, most probably at the quick-fittings. These are the screw connectors that connect the evaporator to the compressor.
In my case the problem was a leaking heat-exchanger (the tube on top of the compressor) that rotted away due to the salt water in the circuit. In the end I replaced all the compressors.

Thanks Arno

Do you know where this filter is located by any chance?

Also, in the probable case I have a leak, how did you conclude it was located in the seawater heat exchange?

We have the original units ; the rpm control is a simple philips screw driver operated potentiometer.
