BACKSTORY
While trying to repair the wiring, a copper conduit (likely not what it is called) fell down into the hull.
Q3: is there a source for just replacement parts for the OEM lamp?
I want to keep the boat as original as possible so parts are my first choice.
Q4: where can I get a picture of the part I lost?
The part I lost is a small copper rectangle that connects the lamp to the wiring—clearly I am not an electrician. I could attempt to make a replacement for the part I lost.
