July 19th - Doin' the Charleston
We pulled into the Charleston area early in the morning after an absolutely marvelous sail. Lydia had gone down to sleep after letting me sleep longer than the expected midnight change, and in return, I kept at it until past dawn and our entrance. That sleep deprivation would come back to haunt me later, as the out of sequence posting demonstrated a few days ago. We got Larry on the phone and were directed to a special entrance we'd missed both when looking at the electronic and paper charts of the area. We were also directed to the City Marina as necessary for us to accomplish what might be refrigeration repair (more difficult for a service person to dinghy out), electrical troubleshooting, instrument repairs and the like. As much as it's against my religion and our budget, we bit the bullet and signed up for the Franklin plus daily fees to be at the (very VERY long dock - the MegaDock, where the big guys park) end of the outside floating dock. Larry had his hand-held VHF radio with him and was able to hear our traffic with the control for docking and thus was waiting for us when we landed. We quickly connected to shore power and commenced to troubleshooting while Lydia went off to discover who she'd chat up in THIS marina (if you let her off the boat, she's gone for hours, as there isn't anyone she meets who doesn't turn into a conversation, some of which involve geneology, let alone hail-fellow-well-met). We quickly determined that we weren't getting nearly enough power to the batteries which appeared to be OK, but very low. Larry's first supposition was that the batteries were dead, but futher digging showed that the charger wasn't putting out anything like the 70 amps it was rated for. Out come the manuals and to cut it short, the charger and its controller were fried, literally (see gallery pix). So, the first order of business, as long as we're on someone else' (expensive - a surcharge of $6 per day) electricity, we need to get something to accelerate the charging, so it's off to West Marine. New charger installed, we're topping up the batteries. To do our tests, we've turned on everything we can find to generate lots of load. If our charger is up to the task, it should shoulder all the load and have some left over. However, as we put all that we can find into the system's load, it turns out that it's high enough to take all the charger has to offer. As it's a relatively small charger, that's not really surprising - we have lots of time when connected to regular 110V power, so it's not worrying. However... Then, while it's working, we check the alternator (the busy thing on the engine which is supposed to not only supply the electrical needs while operating, but have lots left over to bring the battery up to cover the non-running times' consumption. We'd assumed we had high output alternators based on the markings on at least one of our spares. NOT! Just like the case marking sez, they're suitable for charging the starting battery, and nothing else. No wonder we've got low power. We've been assuming all along that our alternator was not only keeping up with the running load, but could easily cover other loads (like this computer!) as well. Instead, we've been steadily sucking out the supply, rendering us nearly bankrupt in power terms. (You look at a boat's electrical system like income and spending, with the bank - except it can't be filled beyond a certain point - supplying the extra, such as drawing from your savings. We were making far less than we were spending, and our "bank account" - the battery bank - was nearly empty...) It does its thing overnight - so, now it's the 20th. More working in the engine room. As it's cooled down a bit, I go in with one of the two spare alternators I have, and change it out, on the thought that perhaps the one which has been on the engine since we bought it was somehow defective. Ever hopeful, perhaps this one is 70 amps? Nope. Same basic output. If we load up everything possible at the same time, it's more than the alternator can supply, let alone fill the battery with the excess. All this alternator testing makes for a very hot engine compartment, and heats the rest of the boat. Our marvelous extraction fans do a great job of pulling the hot air out of the engine room, but are awfully hungry for electricity to feed them. As we're trying desperately to charge up the batteries, that's not a good thing. So, I continue to work on in the heat. Making it worse, I got only a few hours of sleep last night, as we were up until the wee hours. Tonight's no different - I was so out of it from the heat and lack of sleep that I posted our third day of the trip before the second! So, we'll continue this saga at a later time. In the meantime, it's been great to actually meet the guy with whom we've been corresponding, skyping (internet telephone, with pictures, sometimes, even), phoning and otherwise picking his brain. Later, we'll do some basic touring, but save the high activity levels for our return trip when we're not trying to get to NYC.
