Fire or Explosion Hazard!
Electrical system parts are designed by and
manufactured to comply with the US Coast
Guard requirements to minimize risks of fire
or explosion. Never substitute automotive
parts for marine parts. Automotive parts do
not provide the necessary ignition spark
protection.
DO NOT tamper with any electrical connection,
panel or harness, or attempt installation of any
electrical equipment unless thoroughly familiar
with the systems and experienced in making
such installations.
Circuit breakers are installed on the battery switch to
protect various system components. The SHIP SYS-
TEMS breaker supplies power to all DC electrical
components except the aft bilge pump and forward
bilge pump (if applicable), stereo, ignition, and instru-
mentation. Additional breakers are located in the cabin
circuit breaker panel. The circuit breakers and/or fuses
are labeled for amperage and use.
The dash components are protected by a fuse panel.
Refer to Figure to the wiring schematics in the back of
this manual.
