In general, when on the boat, you’ll have all the green and all the yellow breakers “ON” with the Macerator Pump, Fuel
Transfer Pump and Oil Change Pump “OFF”.
When not aboard, only the green breakers may be left on.
4G5: DC Switch Panel, Helm
The DC Switch panel located at the pilothouse helm
controls a number of auxiliary items; some of these are
also controlled at the upper helm.
4G6: DC Voltmeter & Ammeter
At the top of the main Breaker Panel are the electrical meters, and the
right-hand two show house battery DC voltage and current.
More readings are available at the inverter control panel; see page 30.
Since the house battery is the primary power for instruments,
lighting, and other important vassel systems, you will want to monitor
it! Whenever you are dependent exclusively on battery power
(particularly before retiring at night or leaving the vessel at anchor)
you should get in the habit of checking the ammeter to be sure that
you are not running down the batteries with some extraneous unit turned on.
