Batteries, combination parallel and serial
James Sterling
I'm about to replace my group 27 wet cells with group 31 AGM's. My bank has 8 in parallel connected on the negative by twos with copper plates. Since the AGM's are a little wider, jumpers will replace the copper plates. There are 4 along side the front of the bank (end to end) connected in serial. In researching this in the group, I see BeBe's bank which appears to have 8 in series and 4 in parallel. This confuses me a bit. Can anyone enlighten me? I want to make sure I do this right.

Re: Wiring path Info
Hi Amelians
I hope everyone is having a good season, wherever you are. I am replacing the bow navigation light fixtures, and need some advice. I can't budge the cable that goes from the port bow locker, up the pulpit stanchion,, around the upper pulpit tube, and down the starboard stanchion to the light. It won't move a mm from either end. To make matters more difficult, I'm single handed and can't work both ends at the same time. When the cables are stripped back a ways, the inner wires are black, but not brittle. If I scrape them a bit with a knife, they are shiny copper under the black. Unfortunately the two terminal wires to the fixtures were joined to the cables from forward by a non waterproof junction, and the cable from forward has the same issue. Inner wires darkened, but not brittle. I think they should probably be replaced, but it's going to be a major project to get the starboard wire out for replacement. I've already taken Eric's advice and removed the port stanchion from the rail, still can't budge the cable. Any advice? Either for how to remove the old wire or what the issues are for leaving the old wire in place and securing all connections in a waterproof manner. Thanks in advance for any wisdom you can pass on.

Caleffi Mixing Valve
william_maffei@...
Hey Everyone - I have an issue where my H2O pump cycles on which tells me there is a break in pressure somewhere. I have begun tracing the lines to find the source. I have a Caleffi Mixing Valve that I would love to learn more about. Anyone have any experience with these? Mine does not move from the 3.5bar mark on the pressure gauge. Thinking it might need a cleaning/service or replacement. The gauge on my water pump shows accurate pressure so it leads to to believe this gauge is not working... or I just know nothing about it. Can anyone provide some insight? Many thanks, Bill Maffei SM# 195 It's all Good

Re: [Amel Yacht Owners] Climma AC Capacitors
greatketch@...
Makes sense. A run capacitor should last 40k hours or so. Start capacitors less so. I must just be on the lucky side that none of the many motor driven things I have repaired ever needed a capacitor to get running again.
toggle quoted messageShow quoted text
I often make the erroneous assumption that other people use things on their boats in the same way we do. For us, accumulating 40K hours on our AC units would take about 100 years--we use them that infrequently. We also have a boat a bit simpler than many and just have fewer capacitors on our boat with just two AC units, and no other AC motors other than the clothes washer. We had the original Cruiseair AC units when we bought Harmonie. One compressor had an internal check valve fail shortly after we got the boat, the other is still going strong. We thought--briefly--about replacing the failed compressor, but by the time we added the cost of parts and labor, and other potential issues with an old unit, it was more cost effective to just replace the whole thing since the install labor is free (me). On a closely related topic, do you know what brand of compressor the Climma units use? Bill Kinney SM160, Harmonie Boston, Mass ---In amelyachtowners@..., <yahoogroups@...> wrote : Bill, It may be just the numbers.

The Climma fan speed capacitors are critical because sufficient fan speed is necessary to keep the high temperature interrupt switch from opening...and, of course sufficient fan speed is required to sufficiently cool. I think that the majority of SM owners in this forum have 10-25 year-old Climma AC units and every one of those capacitors is at end-to-end. That age statistic is amazing for a marine AC, considering most home ACs don't last 20 years...and most home AC units will have a capacitor failure in their lifetime. So, I think it is the numbers.

Re: [Amel Yacht Owners] Climma AC Capacitors
Philippe Morel
About Climma capacitors , we are in Colombia with a AC failure . Specialist that come , explore unit and test capacitors , nothing but after extraction of compessor oil ( 50 g in the cooling gaz circuit ) , all remain well , even if the compressor seem low in cooling capabilities , mainly due to internal loss of proof between gaz / oil . On our Climma compact 9 , electrical specs are : 220 v + or - 10 % , and 50 Hz + or - 10 % , and capacitors labelling 50-60 Hz , so , to me , I think that electrical failing comes for most from the bad quality of power .

Hi Bill, Remember the our boats are meant to work at 50 Hz we often plug into 60 Hz. The motors run faster and the capacitors definitely do not like 60 Hz. Fair Winds Eric Kimberlite Amel Super Maramu #376

Can anybody explain how I have gone my entire life working around household, industrial and marine equipment, and never replaced a capacitor on a motor, yet it seems to be a routine failure we talk about here? Am I just lucky? Or is there something going on? Now to be fair, very few of the electric motors I have used around boats have been AC motors, so it might just be a sample too small to give useful data.
Is there something special about the electrical supply characteristics or the general environment on board that is causing this? Maybe salt air getting into the capacitor and shorting out the plates?
For what it is worth, I haven't had a failure of a capacitor on Harmonie--yet. (I am sure just that just jinxed at least one of them!) On the other had, we hardly ever use any of our AC motors, so it might just be a usage factor.

Re: [Amel Yacht Owners] Re: Frigoboat two speed fan not working

Duane, See the attached: Page from Amel School Book Part 3 - Mechanical.PDF This is the trouble shooting guide that I have always used. That fan switch is a push button switch. All push button switches are prone to failure when not used frequently. My guess is that you have one of the following in order of probability:

Re: [Amel Yacht Owners] Re: Frigoboat two speed fan not working
Mohammad Shirloo
Duane;
We did not have to pull the refrigerator to access the
compressor. On ours, there is an air intake grill that can be removed and access
the compressor and the compressor controller.
Is the compressor running continually with out
stopping?
In regards to the thermostat setting you mention, I was
talking about reducing the compressor RPM setting and not the thermostat
setting. On ours there is what looks to be a variable resistor (POT) that you
can adjust the compressor RPMs from 2000 to 3500. We reduced the RPMS from 3500
to 2000 to solve the issue.
In regards to the
refrigerant in these compact units, be extremely careful. In my research, the
company indicates that the amount of refrigerant in these units is extremely
small and has to be set by the factory in "Lab conditions" to be able to get the
amount correct. That is why they do not publish amounts or pressures because
they believe that it cannot be done in the field. If an A/C "expert" from an
auto industry, for example, steps on the boat and says that he needs to
charge the system or somehow change the amount of refrigerant, I would not allow
him. The tech must show that he/she is certified by Frigoboat, If I were to
allow them to work on these units. Just my 2 cents.

We have had the frig thermostat set on the highest setting since purchasing

to wonder if it's a slow leak in the refrigerant lines somewhere since it's
gotten progressively worse over time.

Sorry group to pile onto this topic however, this evening I found the forward stateroom filled with smoke. After examination of the AC unit, one of the fan capacitors had a big hole in it. I also located, what I believe are, the two start capacitors inside the control box. Is it a safe assumption that all three AC units use the same 5 capacitors (3 fan and 2 start)? My thought is to replace all the capacitors on all three AC units and put these on some kind of maintenance schedule. Any feedback on whether this is a good idea? If so, how often should they be switched out?
Any input is appreciated.
Thank you. SV Trillium SM215 Brunswick, GA

We've been having higher temps in the Frigoboat refrigerator recently, over 50 degrees F. We have already pulled the unit out and cleaned the heat exchanger, and; made sure that all air supply spots are clear; and are now rearranging things inside to ensure interior air flow. At first that seemed to remedy the situation, but now we're back to higher temps (just a few weeks in between).
My infrared thermometer has 32 deg. F at the coldplate so that doesn't seem to be the issue.
I'm going to order a new thermostat and see if that helps, is there anything else I should check?
While checking on these things, I've found the two speed fan is only working on one speed. I know it worked in the past. Is there a fan capacitor that might be the issue?
Thanks! Duane
