Section 2 - Getting to Know Your Power Package
A 20 amp fuse may be located in the ignition switch "I" terminal lead to protect the electrical
system. Check for a failed fuse if the ignition key is turned to the "START" position and
nothing happens, and the circuit breaker is not tripped.

Audio Warning System
Caution
IMPORTANT: The audio warning system alerts the operator that a problem has occurred.
It does not protect the engine from damage.
Your Mercury MerCruiser power package may be equipped with an audio warning system.
Most faults cause the warning horn circuit to activate. How the warning horn activates
depends on the severity of the problem.
There are three warning horn states:
• Caution
• Severe
• Onboard Diagnostic Marine (OBDM) fault
If a caution is detected, the audio warning system will sound for six one‐second intervals.
