Terminal 30 to Live supply with in line 10a fuse.
Terminal 85 to original horn supply.
Terminal 87 to air horn +.
Terminal 86 to earth.
- on air horn to earth
I've just installed air horns and I'm confident they are wired correctly.
Worked fine for the first few blasts then one long blast and the fuse blew.
Any ideas what could make the fuse blow? It is a 10a fuse as recommended in the instructions..
