Pretty soon Ill rename my boat to "Sinking Devil"!

My horn has never worked. So tonight I took off the horn and hooked up the
voltmeter and put it on DC 10 (mine doesnt have a 12). I hit the horn
button and the meter went from zero to down below zero. It did this each
time I hit the horn and if i held it in it would stay down below zero.

Is this normal? I tried swapping the wires and then it did nothing.

I also tried hooking the horn straight up to a battery and it did nothing.

If that voltmeter reading is correct then I'll buy a new horn for the
"Sinking Titanic" tomorrow.

Thanks fellas,
