The first thing we do is unplug the shore power cord. We want the boat running on her own systems, pulling the batteries down and recharging them, so there is load on the alternators and genset. To make sure the charging system is properly cycled the inverter is turned on along with the electric element in the hot water heater. This really sucks down the batteries. During the night the fresh water pump has cycled several times indicating a leak.
Hose clamps are double checked and several loose ones tightened.
While inspecting the engine room I notice a shiny spot on the hull. A couple of minutes later we've found a tiny leak in the drain valve of the day tank. A quarter turn on the valve solves this problem. All electrical gear is now running. The digital thermostats for the fridge system are adjusted and a log of compressor time is started.
