[C320-list] How deep do I drill?

[Jeff Hare]

Did you try a stud finder to see if you could identify where the wires might be located prior to drilling?

Just a thought.  
My stud finder has a wiring setting that looks for signs of a voltage present (granted it's DC and probably no current flowing so it might have quite a time locating a magnetic field.)

Further to this - investigation showed I had drilled right through a cable so I cut back the gelcoat and dig around and eventually found a coiled length of cable with black and white cores However I seem to have TWO ends, nit sure what is leading where? Have I drilled through some unrelated cable I wonder, nit that I can think of anything else that would run there?
The next problem is finding the other end of this cable. There is a similar cable hanging down hear the holding tank but this is not electrically continuous with the cable at the deck Or is this cable designed to pull a new cable through rather than as an actual electrical connection?
Any help much appreciated!
