All,

If you have already replaced your defective Onan PCB, I would like to have the defective one. One of our members has the contact information for a guy in Colombia who may be the same guy I met in Colombia. That guy is willing to look at a defective PCB to see if he can repair it. 

Let me know if you can help with this.

Re: Electronic technician to Repair Onan PCBs

 

Stefan,

I contacted GeneratorPanels.com by phone. Unfortunately, they do not repair the "Intelligent PCBs" most of us have. They referred me to FlightSystems.com. I contacted them. They do offer board-level repair, but if the memory chip is damaged they cannot repair the board because the software is proprietary. Therefore, they have deemed the boards we have in most SMs and later models as unrepairable. 

I only had the Onan part 327-1533 which was from a late model SM. I would like to ask them about an Onan PCB prior to about 2000. I think this one may not have software controlling the board. It did not have a diagnostic circuit, but simply a "Fault Light" and reset button. If someone could give me that Onan part number, I will pursue the possibility of repair with Flight Systems.

Re: Electronic technician to Repair Onan PCBs

 

Ryan,

No, none of the above. 

In about 2006, I met a Dutch or German guy in Cartegena, Colombia who repaired things like this without knowing anything about its functionality. Maybe he was one in a million. He repaired a sat phone for me replacing a capacitor and another part in the power supply and a resistor and something else in the transmitter. I did not have an account for the sat phone, so he could not test it with a connection, but said it was transmitting and should connect with an account. He was correct. He had never worked on a sat phone before. He typically worked on old TVs for the locals and for sailors visiting there he repaired radars, GPS, Radios, and other navigation items. He refused to work on computers even though he said he could repair almost any electronic issue. I think I know why he refused to repair computers. It was the dinosaur effect.

Obviously, my search for somebody like this is the last resort.

Re: Bonding and Solar Power System

 

Adam,

Lightning: I believe anyone who tells you that there is protection from lightning is probably an ex-snake oil salesman. Lightning is never the same, always different. If you believe there is protection from lightning strikes, I suggest that you ask one of the several people that are selling this stuff.

RF: I believe that you should follow the guidance of many electronic device manufacturers which is something like this:

So, why did they change that block arrangement to the weldment on the 54?
Maybe because those blocks are a real pain to remove, if you ever have to.
I just think the weldment is a much better solution and those blocks disappeared forever when the SM was out of production.

Re: Bonding and Solar Power System

Herbert Lackner
 

Hi Adam,

the "bonding" at the rudder that connects the zincs with all pieces of metal that have contact with salt water is to protect these metals (avoiding galvanic problems). It is not to be used as "electrical ground" or earth connection. Therefore you should not connect any ground/earth connection from any electrical device to this grounding point.

in addition to that, imho, there is no need for connecting the ground of your solar panels, they will work fine if not grounded :-)

Re: Main sheet tackle broken catch

Danny and Yvonne SIMMS
 

Hi Bill. With you on this. II would add use the preventer when running with eased sheets. I also agree with you about weak points. If the boom attachment fails it is an easy fix. Broken boom or rig?, Oh boy. So if the boom attachment fails and we beef it up perhaps we are advised to modify technique.

Just a couple of general observations on the mainsheet to boom attachment on Super Maramus.  I do not think this part is underdesigned.  I think the issue is that boats are sometimes sailed in ways that the designer did not anticipate or allow for.  

We had Harmonie for over two years before I first heard about this issue on another SM.  I saw the damage, and pretty quickly afterwards heard of another boat with the same issue.  I realized I hadn't looked at this part closely on our boat, so put that on the checklist.  A detailed inspection showed that it looked exactly as it did when it left the factory.  This after 22 years sailing on two circumnavigations, and accumulating well over 100,000 sea miles. Based on what I saw, there was no reason to replace or change anything. So the idea that the design was faulty or fragile didn't seem to make sense.

It took me a week of thinking why this disparity might be before the light bulb lite up and the connection was made.  A rigger with a lot of Amel experience confirmed the answer:  Accidental gybes.  They can put a HUGE load on all the parts of the rig, especially the mainsheet attachment.  Everybody has them, (hopefully rarely!)  but with the way the SM is set up we can really reduce, or completely eliminate, damage done if we sail the boat "right".

The key to reducing the shock load on the boom is to ALWAYS, ALWAYS, ALWAYS move the traveler to the side of the boat where the boom is eased out.  That minimizes the length of the sheet, and hence the swing of the boom and the peak velocity of the boom during a gybe. NEVER sail the boat with the boom eased far out over the rail using only the sheet while keeping the traveler centered.  It is very inefficient in terms of sail shape, but much more importantly it is potentially risking damage to many parts of the rig if things go wrong.

I am convinced you can beef up this part all you want, but it you have a full flying gybe, stuff can still break.  I have seen booms snapped in half, and rigs taken down by accidental gybes. The forces can be darn close to irresistible, so everything that can be done to reduce those forces, should be done, and done every time we turn downwind.


Re: Bonding and Solar Power System

 

Adam, In my experience, many marine electricians have difficulty explaining this to you. I am not a marine electrician, but let me help you, at least, I hope, somewhat. I really hope that this does not sound like a lecture as all I want to do is share some experience with you which will hopefully cause you to research this issue more.

You wrote, "It seems that these wires should and must be connected to an earthing point."  This is probably technically true, but probably only if the DC voltage is above 50VDC. The purpose would be to protect you from an electrical shock. Almost everyone agrees that DC electrical shock protection is not needed below 30VDC. Some solar panel installations have been done in series with potential voltages of 3 panels reaching 70VDC. If a wire chafes against the arch, the arch could potentially deliver an electrical shock if you are somehow grounded. The solar controllers I have seen do not have an Earth connection. BUT, even though there may be some risk from these very remote things unless you are connected to shore power you really do not have any available protection from an Earth circuit. However, this may be a reason to wire solar panels in a parallel circuit rather than in series.
image.png

Earth is not Bonding. 

Earth is a safety circuit used on AC current systems. An AC "Earth" circuit is used to protect you from an electric shock. It does this by providing a path (a protective conductor) for a fault current to flow to earth, which is literally a copper bar driven into the earth. Earth is also needed in a GFI circuit to switch off the electric current to the circuit that has a fault. Earth is for AC circuits, not DC circuits. In the US earth wires are green. In the EU, and elsewhere earth wires are yellow/green. Amel's bonding system also uses yellow/green wires.

Bonding is connecting all of the items that may be in contact with raw water together and terminating at an underwater anode. The purpose of bonding is to reduce corrosion and electrolysis caused by stray-current and galvanic corrosion. Normally bonding connections are made to all metal items that may be in contact with raw water. Amel takes bonding to the next level and connects even those metal items that are in the freshwater system which are electrically in contact with raw water via the watermaker.

SSB Ground Plane: Amel built your boat with a Ground Plane for an SSB radio. The Ground Plane is connected to boding if you do not have an SSB.
image.png

Isolated Ground is used by Amel on main engines and generators, which is a method of disconnecting the 12-volt negative from the engine block.
DC Ground: Circuits powered by batteries do not have an Earth circuit. Batteries do not have a connection to the physical earth. So most DC-powered circuits, especially by batteries, have a floating ground, not Earth. There are 2 DC Ground circuits on your Amel, 12-volt (starting) and 24-volt (house). The negatives of these should not be connected and they should be isolated. Some owners have used a 24-volt to 12-volt converter to charge the starting battery from the house bank. An "Isolated Converter" should be used in this case.

Other stuff:
Although American Boat & Yacht Council (ABYC) requires DC Negative, AC Earth, and the Bonding System to be connected as one, I personally think that they are wrong and I know of serious issues caused by the connection to DC ground to Bonding. The Amel Bonding system is connected to the AC Earth circuit.

Back to your arch: I am not sure of a need to connect the arch to Bonding, but I assume that it could be argued that it should be connected for the same reason that Amel, beginning with the 54,  connected the masts and rigging to bonding. I assume that this was an effort to reduce corrosion. I personally think that it might have had the reverse effect. I have often noticed the increase in paint bubbling on the rig of 54s and later models and the increase of corrosion of the rails and standing rigging. Some people point to other reasons. I simply do not know, but I believe it is coincidently suspicious.

It is not as simple as some people make it out to be.

I hope this helps.

This post is a continuation of the recent discussion about the rudder post and galvanic protection system. I have discovered that the two green wires that had been disconnected from Flora's bonding system (at the rudder post) are the earth wires from the solar array/panel frame at the stern and from the solar charge-controller/battery charger.  It seems that these wires should and must be connected to an earthing point, so I am at  loss as to why they would be disconnected.  Was it an oversight? Does anyone have some experience on earthing their solar array frame and the associated controller?
