Hi Pat,
 I have just been through the process, on sm251, we only have the sender opening,  I sucked out all the fuel  through the filters with my vacume extraction,  opened up the outlet , put a light into the tank, I used a rag on a stick to wipe what I could, it was one of those job's that didn't really need to be done,  it was really clean, a small amount of dark colored somthing on the bottom. About the size of a saucer.
Just a thought before cutting the top for inspection openings.

Re: Shore power, small battery charger, genset, inverter.

 

Chris,

It is impossible for me to know what has been changed since 433 was built. 

You should not switch power sources with any load. The SM2k originally had an automated relay switch that gave the generator preference and would switch the main AC distribution panel from shore power to generator power. Although it was not the right thing to do, the original battery chargers would be unaffected when this happened. You do not have either of the original chargers. I am not sure that you have the relay switch above, or if the relay switch is working correctly. Your SM did not have a "standard inverter." The comfort pack did not include an inverter. There was a small inverter installed with the TV option. Are you beginning to see that there is almost no way any of us can directly help you with the known information?

As Ryan pointed out, if the Main 220 breaker is opening immediately when the smaller charger is turned ON, the fault is most likely a ground fault. That ground fault is likely an issue with the internal electronics of that charger or the wiring to that charger. There is no way that I can foresee anyone being able to give you specific instructions to a solution. Additionally, I have no technician to recommend in Grand Cayman.

To further confuse the issue, you say, "The large charger is a (Mastervolt) Chargemaster 24/40-3" AND "The small charger is a Victron Skylla-TG 24 100" AND  If this is correct, it totally confuses me because you must have them reversed...the Victron is 100 amps and the Mastervolt is 40 amps. I am not sure which charger is working.

My best recommendation is to temporarily use only the charger that works and to find an experienced and certified marine electrician. 

When you SM was new and assuming it was sold with either the Comfort Pack or the original buyer invested in two chargers, they were: Dolphin 100 amp charger and a Dolphin 30 amp charger.  During most of the SM production, Amel did not have an inverter option but installed an inverter that the owner would provide. They installed it in the engine room and with separate circuits and receptacles for the inverter output. The AC panel and the Inverter circuit was totally separate. Amel also installed a small inverter with the TV option. That was located under the nav table. Many owners have since installed Victron Inverter Chargers rewiring the AC panel to give the Microwave and outlets direct "inverter only" power from the inverter charger. The Victron Skylla-TG 24 100 is a charger only, without the inverter capabilities.

I hope this helps you. If you would care to call me, maybe I can provide more help...number below...WhatsApp is fine.

Hello Bill,

              Thank you very much for responding so swiftly.

   I am with my boat in Grand Cayman, Cayman Islands. I had assumed the small charger and the 24V to 220V inverter were part of Pure Magic's comfort package, but other than the manufacturers' operating manuals - which I have read - I am not aware of installation documentation specific to my boat. Pure Magic had one previous owner and it may help if I contact him to see if he can fill in the information. If the problem with switching on the small charger and immediately  tripping  the main 220V breaker in the autopilot compartment (and this developed only after mistakenly starting the genset with the small charger still switched on - which the SM manual expressly advises against) does not sound familar to any one, then I should probably choose between looking behind the 220V switch panel or inside the small charger for a short ( after isolating the boat from mains power) or involving a specialist electrician. I am curious to know what type of damage risk the SM manual is cautioning against when it stresses the importance of not starting the genset when there are appliances still switched on at the 220 V switch panel.Is it damage to the genset or damage to the appliances?

  If there is any other approach you would recommend I'd be grateful for your advice..

A55 # 003- MERIT Angelo Gandola gangaway problem

Jose Alegria
 

Dear amelians

Today de Angelo Gandola gangaway   suffered a very slight touch against the rock pier.
It does not respond to wireless, nor to wired remote control.
The circuit breakers are operational and apparently the entire electronic circuit is working.
All suggestions are welcome to put manually the gangay inside to avoid touching the dock again and how to find the cause of the gangaway not working.

Kindest regards

Chris,

On our SM, the main circuit breaker is also a GFCI.  On mine, this is indicated by a label reading "I∆n = 0.03A" on the circuit breaker, which means it has a 30mA ground fault limit.  Given that your breaker is tripping instantly and there is no sign of overcurrent (presumably the branch breaker for the charger is of a lower rating than the main one, so it should trip first), I bet you're seeing a ground fault.  This could be due to a failure inside the charger or something entirely unrelated.  Is the charger specified to accept both 50Hz and 60Hz AC?

I agree with Bill, although I would note the Victron is the large 100amp charger and the Chargemaster is the small 40amp one - you may have reversed that in your post. A starting point may be to check the connections at the circuit breaker of whichever unit it is that's tripping the mains and at the unit itself. 
Both units are 3 stage chargers and the step down points are controlled by the battery voltage, not by the % charge, so, no, you can't adjust for that. There are some adjustments you can make that are covered in your instruction manuals, but it's unlikely any are needed.
Sorry, but can't help with where your inverter is.

Re: Masse negative leak

 

Good luck. Let me know how it goes. Sometimes the cause is evasive. I should have also said the most probable suspect after the macerator pumps is anything that you have added or changed AC or DC since the MASSE last reported no negative fault.

I did it by unbolting at least one of the main switches and pulling it aside. 

You can also remove the positive wire from the battery bank to the switch by unbolting it at the junction block inside the battery compartment and also remove the positive wire on the starter battery. An alternative in the battery bank which may be easier is to remove the positive wire from the battery post each of your 6 pairs of batteries (the one to the junction block).

Ofer & Nick,

Remember, the minus Masse Light means there is a connection between 24-volts negative to the Amel bonding system. The most common issue is a Jabsco Macerator pump that has developed a leak at the seal, causing a connection to the Amel Bonding. Start by disconnecting the green/yellow wire from each macerator pump. If the light no longer comes ON, you have found it. Replace that macerator pump and reconnect the green/yellow wires.

If it was not the macerator pump and the light is ON for the (-) side, it is more difficult because the individual 24-volt breakers only turn OFF the positive side (+). For a negative side (-) Masse fault, you will need to disconnect the negative wires from the negative main battery switch. On most Amels, this is the lower switch. When the light goes out, you have narrowed your search to one main circuit.

If the (+) side is ON, try turning OFF each breaker throughout the boat one at a time. Don't forget breakers for the windlass, winches, and breakers in the engine room. Do this with all breakers.

I hope this helps you.

Shore power, small battery charger, genset, inverter.

Now the main 220V breaker inside the rotary autopilot compartment trips off immediately if I switch on the small circuit breaker. Resetting this trip and leaving  the small charger off restores 220v & everything else on the 220V switchboard works as before. There is no sign or smell of overheated circuitry, but I think there must be a short circuit somewhere. I'd really appreciate advice on how to troubleshoot this problem or could the small charger be fried beyond repair? The small charger is a Victron Skylla-TG 24 100, if I'm looking at the right unit.
 Another couple of electrical  questions while on the forum: the large charger I only use with the genset. Typically the charger starts at about 80 - 90 A, but soon - within a minute or two - falls to 20- 30 A and tails off at less than 10A even though the battery bank is short of a full charge, perhaps down at 70%. Is there a simple adjustment I can make to the large charger to keep up its output until closer to a full charge or does the charger need a specialist electrician's attention? The large charger has operated in this way for at least a couple of years. It is a Chargemaster 24/40-3.
 Lastly, I'd like to be sure of correctly identifying the 24V to 220V inverter, the one described in the owner's manual as being capable of running the microwave long enough from the 24 V battery bank to make a cup of coffee, after which it shuts down. Where is it in the boat and how do I get the microwave to run off it rather than from shorepower or the genset? 
   Thank you for your advice,
      Chris Bromley

hi Bill, Glad it doesn't apply to the SN ;-)

Craig,

 

You are exactly right about leaving the helm for this exercise.  I was single handed for a good portion of my 2018 season and got caught more than once not starting the genset in time.  It created unnecessary excitement.  Now, when going into a new harbor, I begin the process before getting to the first marker to allow enough time.  It is much easier with crew on board as that is a top training activity, and they are responsible for setting it up.

Hi Bill, 
Yes that looks similar to my board

Stefan,

I had it all this time but had forgotten about the fuse & the battery on the mainboard in the Hydra 2000. I suspect something similar in the H3000.

Does this look like what you saw?

Stefan,

Can you tell me what model B&G Hydra you have i.e. Hercules, Hydra, Hydra 2000, etc? Or what year? The reason I ask is the technical information I have on the Hydra 2000 does not show a fuse.

Sorry Bill,
everything is already reassembled but I think about to take photos next time.
I opened  the processor box, wich is right behind the B&G Hydra 2000 MFD, with the 4 screws and there you can see the little 1 amp glass fuse easily. This fuse protects all 4 display devices and the masthead unit as well.

Hi Elja!

Today we checked the processor Blackbox. There we found a 50 cent blowing out fuse.
That’s it. 
The system is working probably and we placed a spare fuse for the next failure with tape outside on the processor box.
If you got some of these problems with your new old system again, just check the fuse. After 18 years they are allowed to blow away sometimes.

Good luck

Re: A 55 # 9 : Chargeing and mastershunts

 

Craig, I have known Amel to "learn" and add recommendations that did not exist 30 years ago. I don't know when the generator recommendation started, but it in fact does exist.

Hi John,
I stand corrected, thanks.

That you must leave the helm, go below and take, what?, 2-3 minutes to fire everything up, then return to begin docking strikes me as a procedure destined to be ignored.

Be that as it may, I can say with absolute certainty that Amel never gave that instruction for the SN ;-)

Re: Masse negative leak

 

Nick,

I did it by unbolting at least one of the main switches and pulling it aside. 

You can also remove the positive wire from the battery bank to the switch by unbolting it at the junction block inside the battery compartment and also remove the positive wire on the starter battery. An alternative in the battery bank which may be easier is to remove the positive wire from the battery post each of your 6 pairs of batteries (the one to the junction block).

Thanks Bill,

Alas it is not the Macerators. I hate working in the space for the main battery on/off as it is so easy to short out the positive to negative with a ratchet handle... maybe I can cover the positive with plastic sheet or something...

Ofer & Nick,

Remember, the minus Masse Light means there is a connection between 24-volts negative to the Amel bonding system. The most common issue is a Jabsco Macerator pump that has developed a leak at the seal, causing a connection to the Amel Bonding. Start by disconnecting the green/yellow wire from each macerator pump. If the light no longer comes ON, you have found it. Replace that macerator pump and reconnect the green/yellow wires.

If it was not the macerator pump and the light is ON for the (-) side, it is more difficult because the individual 24-volt breakers only turn OFF the positive side (+). For a negative side (-) Masse fault, you will need to disconnect the negative wires from the negative main battery switch. On most Amels, this is the lower switch. When the light goes out, you have narrowed your search to one main circuit.

If the (+) side is ON, try turning OFF each breaker throughout the boat one at a time. Don't forget breakers for the windlass, winches, and breakers in the engine room. Do this with all breakers.

I hope this helps you.

Hi Nick,
We had the same problem.
It took long time to solve , because the light was not always ON.

The way to find where  a bad contact between the minus and the grounding system is, is to start from the main switches near the batteries, disconnect each of the cables while checking the light. Ones you find a cable that if  disconnected the is OFF, look for the equipment down the cable and check the contacts and put corrosion x.
We found the problem in the forward locker . We had a leak of water from the new Bad! installed windlass rubber deck switches that created humidity on all electrical motors in the locker.

Good luck with the challenge.
You can call me if you want more info.

Craig,

 

I cannot speak to other models, but in the factory handover of the 55, they made it clear to fire the genset and both chargers prior to starting docking maneuvers.  I am not on the boat now, but believe I have also seen that instruction in the owners manual.
