I checked the horn relay in 300i downtown and there is none in the parts list, the same as exc. 500 I will trace the wires on my scoot tomorrow, as it is stripped down ,looking for a dead short , looks like my starter relay jamed and it fryed my battery, a new one should be in tomorrow,. new starter relay , new battery ,. what else?
I bought a Wolo air horn, it gives a pretty big blast,. good enough with one horn, two horns you will need a relay, as they are heavy on the juice,
