I pulled up the floor panels in the Guest Stateroom and Guest Head and eventually located an 80 amp fusible link that had failed. It was well hidden under the lip of the floor over the bow thruster. I checked my spares and didn’t haven any fuses that small, so checked West Marine ($20) and Amazon (2 for $5), and I’m sure you can figure out which one I ordered.
Then I went around the boat, checking the windlass control stations and discovered the aft station (in the cockpit) was engaged by the weight of a dive tank fill whip that had been draped over the canvas cover for the control station. Damn It Scott!!
I rectified the issue with the fill whip, then spent some time and brute force to get the chain unjammed from the chain stripper and windlass. Eventually, I was able to get everything put back together like it should be and I replaced the 80 amp fusible link. Fortunately, that restored windlass functionality and taught me two important lessons.
1. I typically leave the power on to the Windlass as a safety measure in case it needs to be deployed or recovered in an emergency. Now I’m thinking I should disconnect the power when I’m here at the dock (even though the breaker is hard to get to).
2. Don’t set things on top of the aft control station unless you want a big pile of anchor chain jammed up on the foredeck. All I can say about that one, is DOH!!!
