Hey Fred, I don't think I want to run something quite that big but I do think you're right, I may want something more than 1.5 amp. I just want something good enough to pass inspection. If I'm counting on people to watch out for me because of my horn I think I may have more problems than just one. If I have to run a relay I will, but did the stock horn require a relay?
Hi Van,
the stock XS650 horn is wired direct but it does define the term pathetic bleat.
Any good horn is a power hog and will work better run through a relay so that neat little pushbutton of yours don't have to switch all that power.
And while the average phone-gabbling SUV driving soccer mom can't even see a motorcycle she just might look around if your horn makes her think there's a semi coming at her.
