So, off we go to Dry Tortugas Thursday evening. We rush to get out of the marina before sunset so we can get out of their funky channel under daylight. Cruising along out of Key West under motor, I check the alternators to find that the new alternator is not quite doing what it’s supposed. It’s putting out amps, but not nearly as much as it’s supposed to. But, thanks to some new wiring I did during the reinstallation of our alternators, I manage to get the engine alternator to charge our house bank, so all is still good. We decide that we can make the 2 day trip with one fully operational alternator, and we’ll deal with getting a replacement for that new alternator in Mexico. So we keep going.
About 5 hours into the trip, more than halfway to Dry Tortugas, I wake up from a nap and go below to check our course on GPS, and some other checks. Oddly, I smell something burning, but I can’t put my finger on where it’s coming from. After some sniffing around the engine compartment, I decide that it’s not coming from there. After some probing, I think I narrow it down to the nav station area of the salon. After some more sniffing, I open the DC power panel and notice that there is some SERIOUS SMOKE coming out of it!!! This is bad.
The heart of the problem is actually where the battery power enters the panel. The terminal for those battery wires is SUPER HOT, and smoldering at this point. I put on an oven mitt, and try to pull the plug to see if I can rerig it without the need for the melting terminal. In doing so, the whole panel zaps out, and we now have NO DC power. No autopilot, no instrumentation, no running lights! This is not bad. It’s REALLY REALLY BAD.
