I upgraded my bike's horn. If I stayed on it for more than 2 secs, it would blow the 10amp fuse. How bad would it be to put a 15amp in place?
Just plug and play off the OEM horn. That is kind of what I was thinking and since I rarely use it wasn't super concerned.Wire might get a little hotter.
Is the horn powered by a relay to the battery, controlled by the horn switch?
If not, the horn button contacts could fry over time.
