I am adding the second horn on my 31 and I discovered that both terminals on the horn are hot[they light my probe light] I also checked the wire to the horn button and it is hot also,I would have thought that grounding to blow the horn the ground side would be dormant.They both blow real good but I can't find a reason for the feedback to the horn button.It is not enough to blow the fuse, It just dosen't seem normal. Any ideas?

Ok, that is the way the thing works, the horns are hot, the wire up to the horn button is also hot, the horn button connnects the system to ground to complete the circuit and blow the horns. The horns are above ground.

There is an "S" wire inside of the horn button and it has two wire "legs" that touch the brass ring on the mast jacket bushing inside of the mast jacket when the horn button is depressed. Therefore, when the contact is made via the "S" wire the circuit is completed and the horn sounds.

Thanks guys ,I was not sure and wanted a second opinion.They sound real good as a pair.

Cool!
