Peter, It was great to meet you at TFest Melbourne. In answer to your question, Winnie the Pooh has a simple but robust electrical system. There is a 700 AH house bank(4 L-16 6v batteries) and a small engine starting battery connected by a 1-2-both switch. Charging is by a 140A alternator on the engine controlled by a manually adjustable automotive regulator (mounted outside the engine room, where it;s cool. The regulator is adjusted by a small screw on the front, from 13.45v up to over 15v. I set it at 14.3 when we are charging at anchor(seldom), and 13.5 when we are running the ICW everyday 8-12 hours. A Heart Link 1000 battery monitor tells me when to recharge the house bank, and also monitors the voltage only on the starting battery (what more would you want to know?). The Link 1000 also controls the Heart 10 inverter/charger. Finally, a Siemens 75 watt solar panel on top the Pilothouse contributes to the house bank (25 AH/day in good weather)about 1/3 of our daily needs. Coupled with a miserly 4 cu ft refrig (32 AH/day in 80degree weather), we can stay 6-7 days at anchor before we need to start the engine to charge. It's good to be back on the list, but don't expect timely replys, we can't always get to a library to use the internet. == Mark Richter, M.E., aboard M/V Winnie the Pooh custom Morgan 46 Trawler.
