July 21st - Hot time in the old town, tonight
So, now a few days later, we're correcting these electrical problems before trying to determine exactly what's up with various instruments. One clue about all this was found last night on the way back from the showers: As I walked down the extremely long dock, I noticed what seemed to be a strobe light atop someone's mast. That someone was me, and the wind speed instrument's cups were interfering with the view as they went around, making it flicker. Once I had that figured out, as that phenomenon stopped as I got far enough along to have the cups in front of (rather than obscuring) the view of the lens, I continued on. Then it looked as though it was dimming/burning. I stepped back, and it stopped. Forward and it started again. WTF??? The way navigation lights work, in order for people who are looking at your boat at night, is to have certain lights visible from certain angles. When you get past that angle the visible light disappears. So, what I'd been seeing wasn't our anchor light - it was the green light showing from the right side of the top of the mast. I'd thought it looked a bit odd, as the white anchor light is very bright and sort of blue in color. No wonder... But, back to the story, as I got closer to the boat, I found the green light disappeared (which is how it's supposed to do) - but not before the red light started to show up and confuse the view. Being much lower than the mast and not off a half mile or more, the view was very small as compared to the output of the light. Thus it looked as though it was getting dim - but in reality, it was showing both red and green together, and as I got closer, red only. Because I was nearly directly under it, I didn't get much of the light by that time, making it difficult to determine what it was. Walking further down the dock allowed me to see more of the light, to the point where the red and white were visible at the same time. BRIGHT red light... So... The red light's lit - at least for now. I'd lit the nav light when we were powering everything we could touch in order to see how much the alternator was putting out, and had forgotten to turn it off. If in fact it's not broken, I presume it to also be a voltage issue (most of our instruments have been misbehaving - see the "how revolting" post - we presume them to be under-supplied). So... Perhaps all of our electronic glitches (the radio aside - one of my contacts has provided the link to the solution in our Ham and SSB radio) can be resolved merely with the application of adequate power. Today has been somewhat of a lay-day, in boatyard terms, in that not a great deal has happened. I've restowed the maelstrom, which resulted when Lydia emptied our storage that hid the wiring I needed for final installation on the new charger. In the process, I uncovered the other spare alternator. It's got labeling on it saying it's 70A. I'll install that tomorrow, along with a new belt, as the one that was on it has pretty well been used up. There's also some possibility that the worn belt was a contributing factor - who knows? - maybe they are *all* 70A and we're just not able to pull it out of them? I'll also be making the final wiring of the charger. It's been in a temporary location as we were doing our testing. If the new alternator and belt *does* produce that higher amperage, then we'll keep it. If not, we're in for some higher output, new, charging on the engine. Tonight we had a lovely evening aboard an Island Packet whose owners have been following our adventures on line. We find we're notorious (in the definitive, not pejorative, sense of the word) as a result of the internet. Earlier today there were a half-dozen dock-walkers from other boats who stopped by and marveled at what we'd done and been through. They also admired the burnt-out hulk of our old massive battery charger, sitting on the dock, waiting for removal... I've also worked on pictures. I absolutely detest Shutterfly, but if one has only a dialup connection, those tiny thumbnails will be visible without waiting an entire day to see them. So, there are pix at http://share.shutterfly.com/action/w...0CcN3DFqybMXNw. However, there's also pix at our gallery www.justpickone.org/skip/gallery - click the first picture, and follow the links. The thumbnails in those galleries are as big as the shutterfly full pix and can be clicked to see larger detail if you like. Getting those together and up kept us up late again, so I'll try to sleep late before I head back into the engine room! As I write, it's now Sunday Morning, and I'm off to deliver the USB hard drive I copied 20Gigabytes of music onto for our Island Packet friends, coffee in hand. Then it's back into the engine room! Having now exited the engine room, there's lots done there. It remains to test it all. However, the battery condition is now in the "charged" zone for each of the dozen cells, where none of them were there on our first reading a few days ago. Unfortunately for me, the alternator which I put on (the one with the 70A label) had a stripped mounting tab, and I had to come up with a bolt which would go through in order to put a nut on it on the other side. Dad's Hardware Store (the name the kids used to give my supplies at my land- based home, cuz any time they needed something, it was available, in stock) has migrated to being Dad's Chandlery. While it's still being stocked, and therefore we didn't have the truly proper bolt for the application, we did, indeed have a makeshift solution. That temporary fix will be resolved as we get confirmation of whether or not the alternator will actually keep up with our loads, and fill the batteries as well. Now that our refrigeration (34.3 currently) and freezer (7.1 currently) is no longer a concern, and we don't have to worry about a repair person coming aboard to work on it, we'll probably ditch the lovely electrical supply here, and anchor out to test out our ability to make power on the hook. We'll no longer be able to leave our laptops up all the time, but when we're cruising, we won't be able to do it then, either. So, we'll get into our cruising mode. And, perhaps, tomorrow, we'll do our electrical loads test, recording each and every thing we use as to how much power it consumes. From that, we'll be able to develop a power budget, making sure we always have more power coming in (over the long haul) than we are spending. We have what, for most boats this size, is a massive battery bank, so our storage should be sufficient to handle low-power-generation days. We just need to be able to identify our loads, and utilize our power judiciously. So, I'll leave you here, and we'll go get some dinner. Fortunately for us, it's moderated in heat recently, which makes being below in the engine room much more pleasant. That's the forecast for the next couple of days; perhaps we can get all of our heavy lifting done before it gets hot, and concentrate on some seatrialing to prove out what we've done. Stay tuned :{)) L8R Skip Morgan 461 #2 SV Flying Pig KI4MPC See our galleries at www.justpickone.org/skip/gallery !
