What this video covers

The rapid dissolution of a propeller anode on a newly launched wooden boat indicates severe galvanic corrosion, prompting a systematic search for stray electrical current.1:08 The owner suspects a DC leak within the boat's wiring, as the vessel has remained primarily on moorings and at anchor rather than in marinas.2:33 Using a multimeter to measure current at the main battery fuse, the owner isolates the DC distribution system by shutting off all breakers and individual circuits, including bilge pumps.12:45 After testing every circuit—including navigation gear, lighting, and charging ports—the diagnostic process reveals no measurable DC current leakage.22:36 The boat’s electrical system, featuring extensive use of heat-shrink tubing, dielectric grease, and dedicated conduits, shows no signs of chafing or shorting.22:50 With the DC system cleared, the investigation shifts toward the engine's charging system, specifically potential conflicts between the alternator's internal voltage regulator and an external regulator.25:13
