In the past I have seen people ask for boat wiring diagrams. Many are missing manuals and don't have them for their boat. Here are some sample wiring diagrams I ran across from the USCG. They might at least help to make sure the bases are covered. They surely can't replace a real wiring diagram but it is better than starting with nothing:<br /><br /> http://www.uscgboating.org/safety/boatbuilder/electrical/wiring_diagrams.htm <br /><br />DIAGRAM 1 - Auxiliary Sailboat<br />DIAGRAM 2 - Inboard and Sterndrive Runabout<br />DIAGRAM 3 - Instrument Wiring<br />DIAGRAM 4 Harness<br />DIAGRAM 5 - Cruiser - Wiring - Less Than 50 Volts<br />DIAGRAM 6 - Cruiser - Wiring - 50 Volts or More
