Re: Shore power, small battery charger, genset, inverter.
Ryan Meador
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? Ryan and Kelly

Re: Shore power, small battery charger, genset, inverter.
Chris,
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. Assume you're in the US with 60Hz - where? Craig

Re: Shore power, small battery charger, genset, inverter.
Chris, I am not sure that anyone can help you here with confidence. Almost everything you listed is not original equipment. For instance a big question for me would be: Who added this equipment and is the installation documented? Maybe we could suggest some help if you would state where you are.

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.

Re: Masse negative leak
I have been playing around at trying to identify the leak to no avail. So the next step will be as you suggest. I will disconnect the battery positive cables and the remove all the negative cables from the big switch and reconnect one by one to identify the circuit at fault.

Shore power, small battery charger, genset, inverter.
Christopher Bromley
My SM Pure Magic, hull no. 433, is presently connected to shorepower @ 220V, 60 Hz. During a recent inspection I was asked to operate the Onan genset, but overlooked switching off the small battery charger on the 220V switchboard before running the genset for a few minutes. Everything controlled from the 220V swichboard is working normally except the small battery charger which usually starts off at about 35A. 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

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.

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).

Re: A 55 # 9 : Chargeing and mastershunts
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 ;-) Cheers, Craig

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.

Re: A 55 # 9 : Chargeing and mastershunts
Billy Newport
I just looked on my 55 and there is a 675A master fuse under the nav seat. I used my Fluke to measure the current coming out of that fuse and the bow thruster doesn't draw power from there when I ran it which surprises me but the Fluke doesn't lie. So, there must be another 24V run to the sail locker. I'll try again tonight and measure the current up there instead.

Thanks!! We never had the oil seal...we have taken it apart many times in the 20 years we have her...that is unless it was removed before we bought her....:/ It would be a great help though if you could point it out for us on the plans. We always managed to make the seal with just the gasket maker.... the fibreglass trumpet is not in a good condition anymore, perhaps that’s the problem! Did you make any repairs to that?

Re: SM 1990 drive unit seals
Mitchell Petersen
Hi Helen, I miss read what you were doing. I thought you were referring to the lower unit. As far as your oil leak goes. There is a 85x110x12mm oil seal with stainless steel spring at the top of the lower unit where the trumpet looking fibreglass thing marries with the lower unit. I believe this oil seal is designed to retain the oil, should this leak as a backup you have the silicone gasket you are using where the upper unit is bolted to the fibreglass trumpet looking thing. I would guess this oil seal has been dislodged or damaged when the upper unit was repaired/ reinstalled. The lower unit needs to be removed to replace this seal. This is not a difficult task once you have the upper unit off but the boat obviously has to be out of the water. For economy I just replaced the oil with engine oil as originally recommend by Amel. When examined all gears top and bottom had very little where so I believe engine oil is sufficient to use in this light application. It is my opinion damage caused to these units is most likely often from miss aligned engines rather then anything to do with oil grade. Let me know if it is unclear where the oil seal is located and I will mark it up on the plan. Mitchell
