I meant to say well done to all those involved with setting up the new owners site. Thanks.
Good bonding connections????
How good can we expect the connections on the bonding circuits to be? I note that on my boat and from pictures in the owners manuals that the yellow/green wires that are used for the bonding circuit are not tinned (I think) and very often are connected to say a metal object with a hose clamp and some of the plastic insulation removed from the wire, linking one fitting to the next in a ring. These connections will invariably become oxidised and green. Given the very low voltages, the connection will be poor. I have made an effort to improve the connections where practical, by changing some hose clamps for new and cleaning up the surfaces, but I wonder how far to go. I was always taught that one should use a dedicated insulated lug with a soldered connector and a copper bolted on lug for all bonding connections, and to avoid clamping uninsulated wire with a hose clamp to, say, a through hull fitting or a saltwater manifold, for example.
Do you think the original connection system is adequate? How important are these connections? Do you think it a good idea to measure the resistance between the Zincs on the rudder and various connected fittings around the boat? If so what might be an acceptable reading?
