Re: Mounting of the 175 amp alternator on a Yanmar

Hi Mark,

Thank you,

I am using the same setup that was on my old Yanmar. I just had to take off the serpentine belt and change the pulleys to accommodate a V belt. Since the alternator that came with the new engine was not an isolated ground and I did not want to use it as I have a spare from the old engine.

I also swapped the senders from the old engine to the new engine. Amazingly when I plugged in the harnesses, it all worked.

Amazing !!

Hi Eric,

   In case you need a new tensioning bracket for this alternator and engine, I found that the Balmar Belt Buddy w/Universal Adjustment Arm fits and works fine. I just had to "invert" it and move the tensioning hardware to the other side of the bracket.  I bought mine on amazon but all major ships chandlers sell it.

Hi Bill, the Raymarine AIS installation manual states: The AIS700 includes a dedicated grounding point to reduce potential damage caused by near

The VHF has the same recommendation.
So, in your  opinion, is it better to ground these instruments to the RF (SSB), or to the galvanic bond system?

Hi Steve,

Thank you for the photos.

Would it be possible to take a photo from the lower inboard side of the alternator.

I need to see where they placed the spacers of the feet of the alternator bolts.

Betreff: [AmelYachtOwners] Washing machine Amel 54, how to remove

Dear Amelians

The Bosch Washing machine on WASABI is dripping the fuse and I want to remove or replace it.
I tried to pull it out but something is holding it at the back where I have no access. I searched the forum but was not able to find a solution. I can imaging that there are some fixing points with (screws) at the back but I can not get access by hand. Maybe the top part of the Bosch machine can be removed separately to get better access to the back. 

Before I do it with more force and potentially damaging something, I like to ask these wonderful forum for some advice. Does anyone has experience by removing the washer and what is the trick if there is one.

Thanks a lot for any advice and best regards

Re: Electronic technician to Repair Onan PCBs

Stefan Jeukendrup
 

Bill,

The use of  "chips" programmed with internal software (also called firmware) is wide spread these days.
Security fuses inside these microcontrollers dictate wether a third party can read the "firmware" with a programming  tool.
Or not...and that is a very attractive way for a company to control the market.....

Microcontrollers and their embedded firmware are normally very reliable (lightning strikes excluded)
In my experience  most failures on a PCB have to do with the periferals that connect the microcontroller to the outside world: drivers, control lines, protection devices and power supplies.
One can often roughly tell what the function of a "chip" is just by looking at its number, then download its datasheet on the internet and measure if it works correctly.

Avaiable for help, I hope this information is usefull in some way.

Re: Electronic technician to Repair Onan PCBs

JEFFREY KRAUS
 

Bill,
Back in August, while running system checks, I discovered my Onan wasn't working, and the PCB board was the cause.
After a worldwide search, and the explanation (by Onan) that their supplier had gone out of business, the PCB board was unavailable from them. They were trying to get a new company to provide them.
I found one from a company called Arkansas Valley Diesel. It was a few hundred more, but it got me up and running. They had a dozen more in stock.
Strangely enough, in late January, a PCB board appeared in a package shipped from Onan. They had never deleted my order. 
I returned it. It's uncertain as to whether they have a new company producing the board, or one turned up, and with my "engine down" order still on their parts ordering system, they sent it to me.
Perhaps Onan has a new company producing the PCB board. The person I spoke to when the engine down order proved fruitless said they hoped to have the boards available within 9 months. It was about 5 or 6 months after ordering it originally that I got one. 
If they're available, It certainly would be more timely to get a new one then have to send the old one out for a repair.
Best Regards,
Jeff

Re: 24v Raymarine Linear Drive Clutch Opperation by NAC-3

Bill Kinney
 

Installing a 24 to 12 volt convertor for this is like using a sledgehammer to kill a fly. It WILL work, but is  an insanely complex and expensive solution to a REALLY simple problem.  I am a very big fan of Victron equipment, but it really is not the right answer for this problem.

A relay is a bit better, but still much more complex a system than needed.

All you need is a resistor.  Measure the resistance of the clutch coil, and install a resistor in series with it that is as close as you can to match it.  If it costs more than $1 you are overpaying.

Ohm wrote the law. Take half the voltage drop across the resistor and half across the coil. 100% reliable. Just chose the right resistance and power rating.

We have been sailing for 5 years with a B&G 24 volt clutch output feeding a raymarine drive just using a 25 Watt/30 Ohm resistor (over kill, but it was so cheap not worth fine tuning) in series to take half the voltage drop.  The clutch is happy, the drive computer is happy.  I am happy because the whole setup cost $0.89 and has no failure modes I can see.

Keep it simple.

Re: 24v Raymarine Linear Drive Clutch Opperation by NAC-3

Clive Chapman
 

I don’t know anything about this specific system, but is the clutch a simple ‘on’ or ‘off’? If so, you could use a simple 24v relay using it to switch 12v to the clutch (assuming you can source as 12v feed of sufficient capacity from near by). Having said that, as Bill says you need good quality kit, so I don’t know if the price difference from the Victron step down, compared with a marinised relay is sufficient to justify.  


Re: 24v Raymarine Linear Drive Clutch Opperation by NAC-3

 

I think your plan is fine, but I would use a Victron 24 to 12 volt converter. Remember your autopilot is only as good as your weakest link.

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.
