4.2 DC Power System

There are three battery banks in the 12-volt system: Generator Start Batteries, Engine Start Batteries,
House/Inverter Batteries.
The battery master switches are located aft, next to the salon sliding door on the port side. Normally you will
leave the switches in the ON position. There is a DC MASTER SWITCH (it is black) on the left of the panel.
It must be switched to the right for the DC system to work. Note that it will trip if it detects a problem with the
DC circuitry. Note: Changing the position of the battery switches with the engines running will cause
damage! Only change positions with the engines off. Normally, it will not be necessary to change these.
Call AYC if you need further directions.
The DC panel is the right side in the starboard cabinet in the pilothouse. The DC MASTER switch has to be on
before any of these switches will work. Remember, there may be helm switches such as Navigation Lights or
Depth Sounder that also have to be switched on or off at the upper helm.
With the DC MASTER on and the ENGINE START switches on check the level of charge in the batteries by
rotating the switch on the upper right and watching the meter to the left of the switch. This does not show the
level of charge of the inverter batteries. The inverter will show the charge level of its own batteries via the
remote inverter control at the aft end of the wet bar in the salon.
The DC electrical panel (right side of the electrical panel in Pilothouse) shows all the systems supported by the
batteries. You will be turning on these breakers for lights, water pressure, electronics, etc. This will allow you
to manage your power usage. Certain breakers should be turned off after each use (engine room light,
washdown pump, etc). Bilge pumps should always be left on.
When disconnected from shore power (and without the generator running), the 12-volt systems will drain the
house batteries, especially when at anchor. Monitor your batteries very carefully. When anchored, turning
off high draw items (icemaker, bridge lights, refrigerator, water heater) will extend battery time between
charges.
