Installed my stebel nautilus . Went well and used Murphs harness . After blowing the horn 3 or 4 times the inline 10 amp fuse will blow . Searching online it seems most people up that fuse to 15 amp to resolve this issue . Sound right to you guys ? I also wondered if the horn is grounded through the mount. I used a plastic spacer on the install which would interuppt the ground if so and can replace in if nessacary. Thanks in advance !
