OK, I have been chasing wiring issues on my '94 vintage boat. Among them was rewiring the bow pulpit for the bow nav lights, pulling new line for the stern light, and new connections for the macerator. One that remains is to rewire a sump pump from an in-bath switch to the pump. The issue is that a splice separated down the wiring run. So, the wiring run goes from just near a lower cabinet door next to the head, down past all the through hulls in the cabinet, through about a 3" circular cut out in the inner liner and then between the inner liner and hull to the shower sump and entering the shower sump in the same 1 1/4" hole occupied by the shower sump discharge hose and then to the pump. The distance from the cabinet hole to the sump wire entry is about 30". So, what I have tried is having a endoscope affixed to some wire (later 1/4" copper pipe) and leading it from under the cabinet to the area where the wire exits the shower sump. I have been able to spot the wire but have been unsuccessful hooking it to pull it back. Then I had issues with the endoscope that stopped progress.
I ordered another endoscope with an attached camera (vs' the cell phone). So here is my next try: get some flexible steel ribbon, maybe a 1/4" wide. Solder the end of the sump pump wire to it. Push it into the space between the liner and hull. Take a couple of button magnets and solder them to the copper tube I am using from under the cabinet. Using the endoscope, feed that tube to find the steel ribbon piece and then pull it back to the cabinet.
I considered drilling a hole for the wire somewhere else, but looking at it critically, it would only complicate the process. So, any other suggestions, comments, comentary or snide remarks?
