Battery Select Switch - Grady-White 330 Express Owner's Manual

Should the high bilge water alarm activate, immediately investigate to determine the source of
water entry. Also, confirm your bilge pumps are working properly. If the situation cannot be
quickly resolved, contact your dealer and remove the boat from the water. See "12 Volt DC High
Bilge Water Alarm Diagram" on page 8–52 for wiring detail.

The 330 Express is equipped with four batteries and two battery select switches. The batteries
are grouped into two banks, each bank consisting of two batteries wired in parallel. One battery
select switch is designated for each engine, and the accessories operate from the same switch as
the starboard engine. See "Battery Wiring With Select Switches" on page 8–40 for a battery
wiring diagram.
An outboard engine should be connected to each battery select switch. Either engine may be
started with either battery bank by selecting position "1" or position "2" on the select switches. In
normal use, select position "1" on the starboard switch and position "2" on the port switch so that
both battery banks will charge simultaneously with the engines running.
Never turn the battery select switch to the "OFF" position with an engine (including generators)
running as this could damage the engine charging system or the generator control panel.
