Breaker for horn on 360DA

[dlfish702]

Tinkering around the boat today and noticed the horn wasn't working. I reset the breaker at the panel below the wheel but no luck. Anybody change out the breakers here, any info would be great as I'm no handyman.
boat is 360 Sundancer, 2005, 8.1 Mercs

If you have a voltmeter, check for voltage at the switch. If you have 12V there, check at the breaker. If you have it there then it's the horn itself. Mine just died for no apparent reason 2 weeks ago. Mine is electric but you may have an air horn with a compressor, in which case you might have a relay in the line after the switch too. Maybe others with your boat will shed some light.
