Today I learned I can fairly easily trace where individual wires run on my boat using an instrument called a "fox and hound cable tracker", originally developed for telephone installation technicians ($25 at Harbor Freight). I assume both 12 volt and 115 volt wiring needs to be "dead" (unpowered) before I start connecting this tool to one end of the wire I'm trying to trace. Is that how you do it?
