Had a nice day of sailing today despite being overcast and rainy. Tonight the wind pooped out and then clocked around rapidly from Sw to SE so now it's right on my nose. I needed to run the generator to charge the batteries but got the bright idea that since there was no wind I could just charge the batteries with the main engine and make some forward progress at the same time. Well , LuLu must have been watching because shortly after starting the engine and getting up to 4.5 K I noticed that the batteries weren't charging. Panic set in as I raced about trying to figure out what was wrong. I'm leaning over the hot engine trying to see if the alternator wires are loose or if some circuit needed to be reset or perhaps the battery switch was acting up again. In the process, I managed to briefly shut off the power to the chart plotter which then erased many of my waypoints. Luckily, I had only to stop and restart the engine like you would your computer to get the alternator back on line you can see the implications of the main engine not charging the batteries. Egad and little fishes as mom would say. Fortunately I didn't have a heart attack, but I did get angry enough to throw my old boots overboard when the sole came off one in the middle of all this mess. Stay tuned for more fun stuff that is surely to come.
