Re: Wifi extenders and the bonding system

I hope you guys are safe and healthy.
Since I am a simple person who enjoys simple explanations, let me jump in with what I think will help you.
The Amel Bonding Checking System on your Amel 54 looks for a connection between the Amel Bonding System and either a positive or a negative connection to the 24-volt battery bank.
Because the A-54, connects many additional things to the Bonding System than previous models, you have a greater chance of some sort of bridge (connection) between things physically mounted on the life rail, lifeline, masts, or anything connected to these things. Boats prior to the 54 did not have all of these additional Bonding System connections. And remember, it could be something the previous owner or his hired technician did. If the Amel Bonding System is compromised by a "wrong" installation somewhere on the boat, 100% of the bonding system is likewise somewhat compromised.
So, when you physically mount a device on the mast or any of the above-interconnected devices, if that device has an internal electrical circuit (+ or -) connected to the case, by mounting it, you have connected 24-volt battery bank voltage to the Amel Bonding System. To further confuse both of us, the Amel Bonding System is almost universally misunderstood by nearly 100% of people you may hire to work on your boat. Something wired or connected wrong by these good-intentioned folks can totally incapacitate the benefit that the Amel Bonding System brings to you.
On another related matter, it seems that nearly all engine repowers that I have recently inspected were done without 12-volt negative isolation. Of course, the C-Drive will likely suffer a long-term death when 12-volt isolation is ignored. I am guessing 4-6 years and poof!
