ELECTRICAL:
The Seawind 1000XL2 has a 12 volt DC electrical system. Power is supplied from
three 105Ah batteries. These provide power to start the engines, as well as running
all the electrical appliances and instruments.
The batteries on your Seawind 1000XL2 are setup as two separate banks. Two
batteries under the ‘HOUSE’ bank and one engine cranking battery under the
‘START’ bank. If the house bank runs flat or extra power is required the
‘EMERGANGY PARRALLEL’ can be used to join all 3 batteries together to form one
singular bank.
The batteries are located in the battery lockers behind the front seat of the saloon
dinette. Batteries are charged by the 2 x 125W or 175W solar panels mounted on
the targa and by the motors when they are running. Batteries are also charged by
optional charger that is mounted in starboard side locker.
NOTE: The Yamaha 9.9 Outboards only contribute around 6Amps each at full
power and can not be voltage regulated. If all batteries are fully charged with
prolonged motoring the battery banks can be overcharged and worse case acid
electrolyte lost through boiling. In this exceptional circumstance turn on additional
cabin lights while the motors are running to discharge excess current.
The house battery switch can be off but the engine battery switch must be on when
leaving the boat. This allows the VSR to engage and charge both batteries.
NOTE: When using the optional electric anchor winch it is essential that the motors
are running so as to provide additional charging capacity to the batteries. Also it is
advisable to only run the winch continuously for no more than 15 seconds – give it a
break for 30 seconds then run again for 15 seconds if required (depending on how
much chain is out). Doing this, will increase the life of the solenoid.
