Re: 175A alternator belts

Alan Leslie
 

The belts are A section, Yanmar number is 25132-004600, generic A46.

I have found that Dayco cogged belts last longer than standard V-belts. The dual belts on the LN 175A alternator and the single belt for the waterpump and 12 v alterntaor are the same size on the standard Amel set up.

Re: Onan shuts down under load without shutdown codes

Impeccable timing on your circumnav- we are stuck in Hawaii now waiting......had a new shutdown just last night. The AC water pump capacitor caused a genset shutdown at what should have been about 3 KW.....and gave me the wrong code as well. Please post when you discover the solution. I'm sure this will happen to us.

Bill,

 

Is this a piece of foam – about 2-3” -  attached with a tie to the cable? It’s hard to tell.

 

Thanks.

I will soon be replacing the Antenna (main mast), cables and VHF. I plan to thread the new cable from the top of the mast attaching it to the old cable while it is removed. If I can, I would like to keep the foam. I think I could add this as the new cable is being inserted but it is unclear how the foam is attached.

If you can't keep the foam, one can attache cable ties to the cable and keep +/-5 cm of it, a few cable ties every 30-40 cm will take away most of the noice as it prevents the cable to dangle against the mast tube.

Thanks to all for your advice. Where would you set float on your alternator, Elja? I have a separate controller, so I can set float where ever I want it.

Re: Switch to LiFePO4

Then you have to go to Victron , they have a seperate BMS
one for all batteries ,
and then you have all in one hand
Charger/ inverter
Solar regulation
and altinator .

One other question
What happens with the Li Batteries and the BMS
when you take a flshlighit ?

At first I had the same opinion about this. However I did think this over a bit and now I'm not so sure anymore. The point being that with a set of "autonomous" 24 volt batteries you do build in a level of redundancy. If one of the batteries/BMS-es fails you still have the others left. With one BMS. etc. you create a critical path.

I'm not saying that should be avoided at all costs but it does add food for thought into to the discussion. For me I think this technology is still not fully mature in the marine environment. One way to get around the 70-80% problem is sizing you battery system so you don't need the top 20-30% and can never charge them up to 100%. To do this you need a BMS that can (actively) balance cells at any state of charge. I only found one company that sells those at the moment. It also make LiPo even more expensive.

Re: Onan shuts down under load without shutdown codes

Mark Pitt
 

Hi Tom and Kirstin,

I also have had at least a dozen shutdowns in the 17 years that I have owned Sabbatical III and in every case there was a shutdown code, including shutdowns due to a faulty sensor.  So this is a new one for me.

Having a spare central board is a good idea, although now that our circumnavigation is done, not as crucial.  I heard that they are quite expensive.  My wife and I are only summer livesboards now.

I think this is a vital spare part to have on a SM because of how much you depend on 220 v (unless you've done a major lithium conversion).

Hi,

In the long run it is even more advisable to abandon the traditional car batterie style and take one 24 volt 400, 500 or 600Ah lithium batterie instead building it up from 12 or 24 volt sections. 

I would prefer a central based BMS controller supervising the hole batterie at once, not packages without com port where one cell does not know what the other does. 

And you should look at the guaranteed capacity. Means this battleborn has only 90% capacity, according to their discharge graph. In my eyes thats a hint for low quality? 
A good quality batterie, with good chemistry inside, will guarantee 100 to 108% capacity.

There is no "drop in batterie" that is misleading because in the end you need to setup all the electronics, chargers, BMS aso. to lithium. That is the real change. Not in what plastic case the cells are packed.

Using 24 volt units makes sure you will balance cells across 24 volts instead of 2 x 12 volt leaving a potential unbalance between the two 12 volt banks.
For capacity the answer is simple, as much as you wallet can last. You will always find ways to spend the available capacity in the end, so more is better. 

For your chargers you will need to investigate if you can set them to the exact same charging parameters. That may be difficult.
Also think about your charging regime. Again Battle Born was not very explicit about this but if you boat is connected to shore power for extended periods, you should lower your float voltage to reduce the state of charge to 70-80%. This can be difficult to achieve if you have several charge sources as this means adjusting it very precisely, up to tenths of volts accurate.
I did not like the way Battle Born played down this issue but Lithium batteries do not like to be kept at 100% charge level for extended periods. Even Tesla has extended logic in their battery management to handle this issue. So when Battle Born claims it has superior cells that do not suffer from this problem, I’m skeptical.

Just my 2 cents....

Re: 175A alternator belts

Alan Leslie
 

We have the 175A LN alternator on a Yanmar 4JH3TE with double pulleys on the LN Alternator, and single on the 12V alternator.
All three belts are the same... Dayco cogged belts, no idlers, A section belts
Sorry not on the boat can't give you the specs, but they're probably on file on the site somewhere 
I'll check tomorrow

Hello,

I got and tested the Optibelt pullys for 90mm discs. 
And to be tightened over their back. 

Did not change anything. Still dust and wear. 

I will switch to serpentine belts. Can' t be worse.

My theory is that I have been using B section belts (17mm) and the alt pulley has 84mm diameter. (This was what was on the boat when I bought her in 2017.) and  according to belt specs The minimum diameter pulley should be 112mm.
Now Optibelt do a 17mm B section belt that can cope with 90mm pulley. I have ordered a pair but that is still larger than my 83mm.
If my theory is correct then I will have to machine the pulleys to accept 13mm belts such that they do not bottom out as 13mm belts can cope with smaller pulley diameters. 
Alternatively get a 112mm pulley for the alternator but then pulley ratio will be close to 2:1 not 3:1
Or switch to a serpentine belt which involve new pulleys for both alternator and the engine.

So my first port of call is to find out what pulleys other Amel owners are using.

Re: Run 2500w inverter always even on shore power?

Billy Newport
 

Agreed Scott,
Separate charger/inverter is the way to go with Victron and solves this problem once and for all. Just adding sensors all over my boat to measure anything I can think of at the moment. Added a shore power sensor yesterday. My Climma uses about 4kw normally but does spike to 9k briefly on startup I'm assuming. You're victron should have data on its power draw, do you have 24 hours of graphs you can post out of interest? You could get it from VRM Portal if you have a CCGX/GX pushing it up to VRM.
