Im installing an oohga horn and have one terminal of the switch going to an "add a fuse" (size 10 fuse) and the other terminal going directly to the horn. There is only the one singular wire coming out of the horn.
I am mounting the metal plate/base of the horn in order to ground it, however before I bolted it on all the way I barely touched it to the grounded bolts just to test the horn and when I pressed the horn button I got sparks coming from the grounded bolts.
Whats the issue here??
