I have sent a cross section of my rubrail ,from my Super Maramu to Techno Rubber Industries in Fla. ,they will produce a die and sample for my inspection . I intend to place an order as soon as I receive the sample and final pricing. The die will cost me $450.00 ,the rub rail will run somewhere around $11 per ft. ,roughly $1200. The more boats ordering would bring the price down and I would like to share the cost of the die. The rub rail would be slightly off white. Another owner of a Mango has already purchased from this company and was happy with the service and product. Shipping to Maryland where I live is roughly estimated to be about $200.
So if anyone would like to join me in a group buy ,please email me at , sailw32@... . I will give the final number of orders to the company as soon as I get the sample from them. They will then give me a final price based on the number of orders ,the more the less. I will probably place the order within the next ten days,so please get back to me ASAP.
Thanks,

biggest problem with not starting the Gen is that you significantly shorten the life of your lead acid or gel batteries I'm not sure about lithiums just ask me how I know.........after killing 12 lead acid in just 2 seasons

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 ;-)
Cheers, Craig

I want to clean my fuel tank, I can only see one small cap that I assume is for the sending unit. Before I tear off the foam cover glued to the tank looking for a larger inspection port, I thought I would ask if one exists on the top of the tank.

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..

          Thanks again for your help,

             Chris Bromley

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. 

Best,

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,

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?

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?
