Re: New VHF antenna = newly discovered electrical leak!
toggle quoted messageShow quoted text
Thanks Scott for your answers for the VHF. A friend tipped us to use uncut cable ties every foot or so, at say, 120° angle from each others as chaff guards along the mast. Would that be useful/possible in our case?
For the leak, try the bow thruster, ours was located there because of carbon dust. Also try the navigation lights, we had a small leak there too.
Undo the cables one by one until it disappears, but the following can be confusing:
If you have 2 locations for leaks, you can think an equipment is ok because you unplugged it and the leak is still there. So in theory, you should unplug everything and test each equipment one by one by replugging just that component. It’s a lot more work and best done starting from the battery bank to isolate the part of the boat the leak is from. But even that can be confusing because the leak from the bow thruster can be seen in the console section through the command part of the system (the joystick activating the relay). Ask me how I know.
What may help you:
I wired a leak detector that i could use where I was working rather than shout at Soraya for testing with the amel built in tester. It’s a simple LED bulb and 2 long wires. I connect one side to the positive (for testing a neg leak) nearby (but live) and the other to the bonding system, for instance the rigging, the guard rail etc. If there is a leak (ie the neg is connected to the bonding system somewhere), the bulb lights. And even better, the quantity of light shows the intensity of the leak. That’s useful for sorting big leaks (for us the truster) from small ones (for us, the navigation lights).
Hope that helps, good luck.
