So I read Calder's chapters on batteries, regulators, monitors, alternators, and wiring and got a terrible headache. Fortunately, I made friends with another cruising couple anchored nearby. They'd been out for years, along the way fixing and maintaining a similar electrical system on their boat, and they helped me figure out how to reset the interface monitor and alternator regulator, two bits of equipment completely alien to me. In the process, I also cleaned connections and traced all kinds of wiring-that previously had been a big mystery of spaghetti-to their functions and sources. The boys wanted to stay in the San Blas forever, but we needed to get the shaft-seal problem sorted out, transit the Canal, and cross the Pacific before my five months with them came to an end. Their father was meeting us and taking over in Tahiti at the end of February; I had only 115 days left with them, and time was limited. Ever since I'd bought Shangri-La, every little setback felt urgent, like a time sink standing between me and my ability to relax until it was sorted out. When I was very young, I'd learned the hard way all about fast-paced schedules at sea, about relaxing now and paying later. I was trying my best to do things right this time and earn credit toward some trouble-free cruising time in the Marquesas.
