Re: Supermaramu wire sizes?

Dan Carlson

Thanks for the follow up Bill,  I did read about Scott on Tengh rewiring with 2x50mm2 for his 5000w inverter.  I believe others have installed the 3000w with the 100A wire. Can't recall the size inverter that Delos installed or if they rewired.

I did a double take on the resulting wire size from your calculations and I redid them myself and cross checked on a different calculator before I realized that the wire length should be entered in meters not feet.  This results in a wire size of 50mm2 or 1AWG (actually 42.4mm2) for a 4 meter wire.  That is why I wanted to confirm the wire sizes.  My guestimate is that the 100Amp charger has a 50mm2 wire as it looks close to the size of another labeled 50mm wire on the boat.  Then the existing 1800watt inverter looks slightly smaller, like it has a 35mm2 wire and the wire to the inverter looks even smaller, perhaps 25mm.  The wire to the alternator is just a bit larger than the 100A charger, so that could be 70mm2, which would be appropriate for the 175 amp.   The wire to the bow thruster (longest run and highest current @ 300-400A) looks like a 4/0AWG length of have which is between the standard sizes of 95mm2 and 120mm2.

I'm pretty comfortable with the calculations, and I am really just looking for confirmation on the existing wire sizes.

Best regards, Daniel Carlson on sv BeBe, SM#387

You might want to look at this:https://www.batterystuff.com/kb/tools/dc-to-ac-amperage-conversion-run-through-an-inverter.html
3000 watts = 13.64 amps of 220 volts:

So the short answer is, assuming that the 24 volt wiring for the 100 charger watt was designed for 100 amps. You should NOT use that wire because you should expect a maximum of around 140 amps. Not good! So, replacement is going to be required. Since replacement is required, calculate the wiring size needed for the inverter/charger using an online calculator...here is one:  https://www.solar-wind.co.uk/info/dc-cable-wire-sizing-tool-low-voltage-drop-calculator

I am not sure about the length of the cable run...I used 12 feet...it could be 15 feet.

The result above shows required wire is 120 mm2 = 12.4mm diameter, which is about 1/2" diameter

Hope this helps.

Re: Greasing stegring cables

The potential grease port location I spoke of may be easy to reach on one rack, but I am not sure about the other. See below.

I haven't considered that. I assume that you are referring to the racks...the steering cable is sealed.

I assume that the "leaking grease" is coming from the rack housing at one end or the other. If I recall these ends are not perfectly sealed. And as the toothed rack moves back and forth, it could push excess grease toward the ends of the rack housing.

Keep in mind that it is the steel toothed racks inside each rack housing that will fail with excess wear and that excess wear will be very close to the center of each rack. I believe this is wear caused by the autopilot "back and forth motion." It may also be caused by securing the helm in a center position while anchored.

Amel SAV said that they are going to be sourcing these steel toothed racks and have them available, even though the original manufacturer, Ultraflex, has stopped producing them. See the worn rack below:

One rack has teeth pointed upward, the other rack teeth are pointed downward. Tooth orientation, along with primarily
center wear, should be considered when adding grease/fitting.

Translation:Corrugated Washer ---- Teflon half-rings

Possibly, the cover shown below can be drilled to inject grease. If so, this would be a fairly easy modification that could possibly add years of service to the racks.
I am worried that the metal is to thin to take a thread tap. If that is true, possibly it could be drilled, grease injected and a rubber plug inserted. I know there are a few owners who can answer this question. We may need a volunteer to study this further.

Re: New VHF antenna = newly discovered electrical leak!

Sv Garulfo

Hello,

We have a similar issue with our VHF and haven't so far figured out if due to antenna or cabling. (measure of the impedance between the core and shield of the existing system returns a infinite value)

How easy was it to run the new coax cable? What cable length did you get? Is there a dedicated gulley for that cable? Did you find the old cable was damaged by chafing?

On Garulfo, we know the rigging is connected to the bonding system, which we confirmed when tracking a mass leak last year.

As per your mass leak, carbon dust can be the reason for it.

I’ve had VHF reception and transmission problems and recently replaced my original VHF antenna with a Shakespeare 5215. The male connector threads fit perfectly where the old antenna sat on the masthead, obviating the need for drilling new holes for a mounting bracket. In addition to replacing the antenna, I replaced the outrageously thin RG-58U original coax to lower loss RG8X. There are even thicker and even lower loss cables out there but the thicker cables have minimum bend radii that I’d violate given the routing through the mast so RG8X was my compromise.

I’m not sure if it was the cable or antenna, but my VHF problems were solved and I can now hear and be heard from a much greater distance than before!

However a new issue came up. Because of the way the male connector threads contact the mast, the coax shield effectively connects the mast/rigging to the VHF head unit and the head unit grounding wire then connects it to the bonding system. With this connection made, the Mass- light lit up, indicating an electrical leak! If I disconnected the grounding wire from the VHF head unit body, the mass- goes away.

It turns out I had an electrical leak going through my rigging for a while now. The evidence was there - rust spots all over the rigging/liferails and some higher than expected (sacrificial?) corrosion on aluminum parts. Per Olivier, it turns out Amel started connecting the mast/rigging to the bonding system around 2009 for this exact reason - an undetected electrical leak in the rigging with boats that don’t get washed often could lead to electrolytic corrosion.

See: https://amelyachtowners.groups.io/g/main/message/21220?p=,,,20,0,0,0::relevance,,Olivier+rigging+bonding,20,2,0,29761258

I would suggest those of you with pre-2009 Amels test for either negative or positive charge through your rigging. If you have a mass tester light and are pre-2009, it will NOT light up unless you make a connection between your rigging and green/yellow bonding system wires. I would think a simple way to make that connection is a temporary jumper wire between the rigging and say the green/yellow wire at your diesel fill-up.

I isolated the leak to my starboard Lewmar V4 windlass motor. It’s the primary one, so I presume age has resulted in carbon brush dust buildup. I assume cleaning it simply involves taking it apart and blowing/wiping away excess carbon dust? Any tips or warnings before I dig into it?

Re: Marina ZZ bilge pump maintenance kit

- the TF Marine pump is identical to the amfa reya marina zz? Very close with some subtle differences--- and all of the rebuild parts are identical.
- the maintenance kit provided by amel is a TF marine or marine ZZ? (Or are they the same?) The careful answer is, "at one time, I am 99% sure that Amel supplied TF maintenance kits, but I am also 99% sure that Amel supplied some other brand kit which was the same size.
