Jeff Cote of Pacific Yacht Systems experienced an alternator failure while underway due to a faulty fuse holder.1:19 Despite the alternator being recently refurbished and equipped with a new external regulator, it stopped outputting power intermittently.1:25 Initial troubleshooting focused on the ignition wire and the fuse itself.2:02 Testing the fuse with an ohmmeter confirmed the fuse was intact, leading to the incorrect assumption that the circuit was powered.2:28 Further investigation involved replacing ring connectors and butt connectors, yet the device remained non-functional.2:36 Testing for continuity across the fuse holder revealed a complete failure of the holder itself, which prevented power from reaching the alternator despite the fuse being good.3:06 Replacing the fuse holder restored the alternator's operation.3:58 When troubleshooting electrical systems, verify continuity across the entire fuse holder rather than relying solely on the integrity of the fuse.3:22
