This owner's manual contains electrical
schematics and wiring harness illustrations for
your boat (See pages 6.22 thru 6.67). These
electrical schematics were generated by electrical
CAD designers at the engineering division for
technical reference and service technicians. Sea
Ray
®
does not recommend that you attempt to
work on the boat’s electrical system yourself.
Instead we recommend that you take your boat
to your authorized Sea Ray
®
dealer for service.
Sea Ray

the electrical system on any model at any time

obligated to make any updates to units built prior
to changes.
ashore. The zincs will be consumed at a faster rate
unless the marina maintains a protective system to
prevent this. In this case, hanging a zinc in the water
bonded to the metal outlet box on the dock will
reduce zinc loss on the boat. Do not connect this
zinc to the boat’s ground system.
It is extremely important that all electrically
operated DC equipment and accessories be wired
so that the ground polarity of each device is the
same as that of the battery. Sea Ray
®
boats have
a negative ground system, which is the
recommended practice throughout the marine
industry. All metal items (fuel tanks, underwater
gear, etc.) in the boat are connected to the zinc
anode by the green bonding wire.
Electrolysis can also be caused by “stray currents”
due to a fault in an electrical item, even though
correctly grounded. Sea Ray
®
has equipped your
boat with an isolation transformer which isolates
the boat from the dockside electrical system.
