How to Test a Warning Horn Unit?
I would like to know the way to check if a warning-horn unit in my boat
is working or not. I am supposed to hear a beep-beep from the warning-horn unit when I turn on the key to start my Mercury 1995 115hp outboard. But I hear nothing. I am wondering if the warning horn unit is working or not. If I find that it is not working, I will simply replace it without going through further investigation. But I don't know exactly how to test it. The Mercury Service Manual asks me to ground the "tan" wire of the warning horn unit to test it. I don't understand what this means. Can I simply run the two wires from the warning-horn unit to either terminal of a 12-volt battery and see if I can get it to horn? Thanks in advance for any info. Jay Chan |

It means exactly what it says, look on the horn unit for a tan wire, when you find it, jumper that to ground, the negative terminal of the battery or anything connecting to that. |
