Posted April 28, 20177 yr I just bought aftermarket horn for my yamaha sr125 to replace old, rusty, squeaking horn. I have two questions. If i connect it wrongly can i blow a fuse or it will be ok and i will only need to rotate the plug on the horn? And second question how to recognize earth and positive on the horn and on the wires? Picture of the horn attached.
April 28, 20177 yr I may be wrong, but I don't think it matters ? If the two are identical just wire them up the same, shouldn't blow a fuse I don't think  Sent from my C5303 using Tapatalk  Â
April 28, 20177 yr Yep as Andrew said not important, I think you'll fine that the horn is earthed through the mounting.
