Load group 2 on your distribution panel contains the air/cooler pump, air conditioner, helm air
conditioner, and the cockpit coolers. Turning all of these accessories on at the same time will
create a load that is greater than 30 amps.* This load will exceed the capacity of the shore 2
breaker causing it to trip. However, this tripping may be avoided in either of two ways. One
option is to use generator power when you want to turn on all of these accessories at once. The
transfer breaker has a 50 amp capacity and will not trip when all of these devices are started at
the same time. Another option is to turn on these accessories in stages. The amperage draw of
each accessory is at its highest level during initial startup. The total amperage draw from these
accessories may be kept below 30A* by turning on each accessory individually, letting the
startup phase finish (i.e. let the cabin cool down, etc.), and then turning on the next accessory.

The air/cooler pump supplies raw water to the air conditioner, refrigeration unit for the cockpit
coolers, and the helm air conditioner. This pump receives a signal from the pump relay for the air
conditioner unit and cockpit coolers refrigeration unit when the air conditioner or refrigeration
unit is operational. Also, the air conditioner seacock located in the aft rigging compartment must
be open (the remote arm for this seacock is accessed through the fold down door behind the
folding aft seat).

This two bank battery charger is located in the aft rigging compartment near the four aft
batteries. The generator must be running or the shore power must be connected with load group 1
energized for the charger to work. To activate the charger, turn the AC panel breaker switch to the
“on” position. The charger has a built-in isolator that senses the charging needs of all the batteries
and distributes charge accordingly. At the point that all batteries are nearly fully restored, the
charger will automatically reduce the current being sent to the batteries to a maintenance level.
There is a 40A in-line fuse in the positive charging lead to each battery bank. If the charger
appears to be operating normally but the batteries do not recharge, check these fuses and replace
as necessary. See this charger’s Operation Manual in your Owner’s Packet for further information
on the charger. See the 11” x 17” drawing labeled “120 Volt AC Electrical Diagram” for wiring
detail.

The Express 370 is equipped with five batteries. One of the batteries is designated for the bow
thruster and the steering power assist pump. It is located behind the fold-out helm table. The other
four batteries are located in the aft rigging area under the drop-in box, and provide power for the
remaining accessories as well as starting the outboard engines and generator. The four aft batteries
are grouped into two banks, each bank consisting of two batteries wired in parallel.
There are two battery select switches on a dual engine boat and three battery select switches
on a triple engine boat. One battery select switch is designated for each engine, with the
accessories operating from the same switch as the starboard engine. See
“Battery Wiring With
Select Switches (Dual Engines)” on page 8–42 and “Battery Wiring w/Select Switches (Triple
Engines)” on page 8–43 for battery wiring diagrams. In normal use, select position “1” on the
starboard switch and position “2” on the port switch so that both battery banks will charge
