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?

Bill, For some years now I have had a minor leak of grease from the rack&pinion . What do you think about adding a nipple to put a little grease back into the unit .
Thanks,

The cables are sealed.

The racks and pinion have to be disassembled to add grease.

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.

Re: Supermaramu wire sizes?

 

Dan,

Yes, the Amels that I have seen have increased the size of the wiring.

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:
image.png
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  
image.png
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.

The existing cables are well shielded and have shrink wrap covering right up to the terminal lug so the actual wire is not accessible for direct measurements. 

I am just trying to understand the sizes with respect to the various loads.  Several of boats have talked  of replacing the original Dolphin 100A with a 3000watt Victron Multi or Quatro and I wanted to understand the impact in terms of current load and voltage drop potential.

I am sure that you know this: In Europe the wire is sized in square mm. 

You might want to measure the diameter of the existing wire, calculate the area of the cross-section in square mm, then if you need AWG, use an online conversation chart to get to AWG. Here is one:

Hi Kent,
thanks for your advice.
What Eric on Kimberlite reports is really impressive - and completely in line with what I have heard from other sailors with gale / storm / hurricane experiences. 
What our Amel's do stand and perform in heaving-to is already more than amazing, but the Jordan Sea Drogue is 'the saviour'.
I have decided now finally to install one. 
For questions of the bridle (I have a bring at the Stern for solar / wind turbines / dinghy) and retrieval and where to buy I will contact Eric directly. 
Once again thanks a lot and happy saling with JSD onboard without taking her out!

Good day to all.

Has anyone located a source for the Twist Lock Fasteners that are mounted on the hard dodger for locking down the bimini side curtains and the tonneau cover?

I can only find ones whose center hole to center hole measurement for the mounting screws, is either larger or smaller than the 20mm ones that we have on our boat.

Please see the photos below.
