Not a GL1800 horn but some ideas here:
I've been thinking about the wimpy horn on my NC. The horn on my GL1800 on the other hand sounds off proudly. Has anybody but me thought about putting a GL horn on an NC? How do I find out if the wiring will support the GL horn?
I was just thinkin.
From what I can tell, the stock GL1800 horns are 4 amps each. They are wired directly to the horn button without a relay. Unless you can find a set of take-offs for sale cheap where someone has upgraded, they look to cost about $47 each. That is about three times more than the Fiamms which are also about 4 amps each.
What no-one knows is the amp rating of the NC700x horn switch. The safe approach that always works is to use a horn relay because you are increasing the load from 1.3 amps to 8 amps. Or, you could assume that the NC700 horn switch is as stout as the GL1800 switch and wire them direct. Not implying that anyone here is a punk, but I guess you have to ask yourself. "Do you feel lucky?"
Motorcycle don't lie!
If I remember well, someone wired directly to the horn button and and melted it, or am I wrong? Can't locate the post, but I remember this well because after reading it I decided to postpone my onw FIAMM dual horn fitment until I have the time to do a good job with relay and so on
