Fuses and Circuit Breakers

The engine is protected by a large cir-
cuit breaker located on the engine. The
accessories are protected by circuit
breakers on the battery switch panel
and by the accessory circuit breakers
located below the steering wheel.
Wires are color-coded to indicate
which accessory each circuit breaker
services. Some items, such as radios
and bilge pumps, may be fused individ-
ually at the unit. Autofloat switches are
fused at the battery.

Batteries

The batteries, located on the port side
of the engine compartment, supply
electricity for lights, accessories and
engine starting.
The Electrical section of Chapter 7, in
the Owner's Manual, provides battery
care and maintenance instructions.

Battery Switch

The battery switch (located under the
aft sink in the cockpit) has four posi-
tions (see photograph on right);
• Position "1" - Battery "1" provides
power for engine starting and accessories. Battery "1" (only) will be charged by the engine alternator when the
engine is running at high idle or faster.
• Position "2" - Battery "2" provides power for engine starting and accessories. Battery "2" (only) will be charged by
the engine alternator when the engine is running at high idle or faster.
• Position "BOTH" - If batteries are low, provides power for engine starting from both batteries. The "BOTH" position
also allows the charging of both batteries by the engine alternator when the engine is running at high idle or faster.
• The battery switch should be switched to the
of time.
