Finally another update - the saying for today is: Sometimes you win, sometimes you lose.
The plan for this visit was to pull the absolutely destroyed old marine toilet and toss it, and to pull the raritan waste treatment system so I could bring it home and diagnose and hopefully repair the unit. The transmission is 95% rebuilt, I am just waiting on the rebuilt oil pump, which I should have in a week, then I intend to take a few days off, and go down for about 5 days and try to install the rebuilt transmission. That'll be a fun one.
This trip was not one of the better trips down to the boat. I got on board at about 1am, and, as always, checked both bilges. Rear bilge was fine, front bilge was full of water (Not the first time, it was like that when I got the boat, there is likely a very small leak around a thru hull fitting). I had changed the bilge pump out as one of the first things I did, and it has had no problem with the amount of water. Well, for some reason, the bilge pump wasn't working. I used an external pump to pump all the water out before I went to sleep for the night.
The next morning, I got up, and immediately started to try and track down why the bilge pump had failed. What I found out is that not only had the bilge pump failed, but anything that ran off of 12 volt DC power no longer functions, or is even getting power. Yay. So, I spent all day Saturday trying to track down some seriously, umm, modified. wiring that this boat has acquired over the years trying to find a fuse, blown component, breaker, anything. Thankfully I carry my multimeter on my trips to the boat.
The main panel looks like a rat's nest, but the main DC switch does not have power coming in, if I metered it correctly. I am going to double check when I get down there again.
The batteries have been disconnected for 8 months (and there is no house battery that I can find), but the boat has had DC power the entire time, so I am thinking that there is a converter from AC to DC somewhere on the boat that I haven't found yet. I am also thinking that either it gave out or there is a blown fuse, etc., that I have to find.
The other interesting thing? The boat is on shore power and all AC equipment is running fine. Shore power works, my A/c unit, receptacles, lights, stove, fridge are all operating well.
Unfortunately, I was unable to find the culprit, and worried about water getting into the boat and getting to a high enough level, I set up a bilge pump working off AC power to keep the boat afloat until next weekend where I will get back to trying to trace down the issue. After that, I may call a marine electrician. Let me know if you know any good ones in the Aransas Pass area.
I'm attaching a pic of the fuse panel (front and back).
Also attaching a picture of the giant tomahawk I found at the local HEB and cooked on the boat, because, well, when you're having a bad day, a steak is sometimes what you need. Sorry, no pics of it finished, but came out a beautiful Medium rare.
Oh, I did, on Sunday, manage to uninstall and toss the old toilet, remove the sanitation system so that I can work on it, and actually wash down the outside of the boat. it was starting to look a little green from algae growth. Sadly, I forgot to take a picture of it afterwards.
