Further to this topic. Our grounding wire is a braided copper strip approx. 3/8 inch wide and flat. A section has corroded and is no longer attached and that section needs to be replaced. Is this the same thing we are already discussing? Han I purchase o new section of this wire in the suitable length and splice it somehow?

Specifically page 35 talks about DC grounds, galvanic protection, and lightning grounds. For a lightning ground which is coupling the mast to the keel I would consider using copper bar stock. Keep it as straight as possible and if a bend is required, make it gradual. Bar stock of sufficient width so that a hole can be drilled in it large enough to fit a keel bolt. For a DC ground I would consider drilling a hole in the side of a nut which fits the keel bolt. Tap the hole in the nut and then use that to accommodate your ring terminal. Alternatively, you could drill and tap the keel bolt axially and then mount your ring terminal right to the top of the keep bolt. The later option will probably be your cheapest and should keep the terminal high enough out of incidental bilge water. https://drive.google.com/file/d/0BwNze1nnSQ2-U045ODJPZl9Lcnc/view?usp=docslist_api Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD On Mar 11, 2016 9:06 AM, "Danny Haughey via CnC-List" <[email protected]<mailto:[email protected]>> wrote: Hi Eric! If you have exposed threads above the existing nuts, can you just add a lock nut on top to secure the wire between the two nuts?

I can splice wires onto the cut ends to reach the bolts, but what is recommended as terminals to connect the wires to the bolts? It would be helpful if this did not involve unscrewing the big nuts on the bolts, but perhaps some terminals that connect to the top of the bolts?
