Eagle 128 Installation And Operation Instructions Manual page 21

CAUTION:
When using the unit in a saltwater environment, we strongly
recommend that you shut off the power supply to the power cable
when the unit is not in use. When the unit is turned off but still
connected to a power supply, electrolysis can occur in the power
cable plug. This may result in corrosion of the plug body along with
the electrical contacts in the cable and the unit's power socket.
In saltwater environments we recommend you connect the power
cable to the auxiliary power switch included in most boat designs.
If that results in electrical interference, or if such a switch is not
available, we recommend connecting direct to the battery and
installing an inline switch. This will let you shut off power to the
power cable when the unit is not in use. When you are not using
the unit, you should always shut off power to the power cable,
especially when the power cable is disconnected from the unit.

If possible, keep the power cable away from other boat wiring,
especially the engine's wires. This will provide the best isolation from
electrical noise. If the cable is not long enough, splice #18 gauge wire
onto it. The power cable has two wires, red and black. Red is the
positive lead, black is negative or ground. Make sure to attach the in-
line fuse holder to the red lead as close to the power source as possible.
