Kwalter: As I revisited this thread I had the same thought...I should have picked a different name since this is ambiguous...sorry.
hellosailer: Thanks for the confirmation that what you call the 'lightining ground' should be isolated from the DC system ground which includes the engine. And also the confirmation that a steel fuel tank should be grounded.
Since I don't have either shore power or any fancy electronics (not even a hard wired VHF), I think our grounding/bonding plan is about as simple as it gets.
I plan to replace that 'lighting ground' as needed but keep it separate. Then I'll figure out how to re-attach the grounding strap to the fuel tank. I think that should do it.
If anyone sees anything grossly wrong with the above, please let me know.
Thanks for the help
