hi all. i checked for voltage at the relay connector before replacing relay and had 12.5 volts. after replaceing relay the horns worked a few times(sounded real low) then stopped working. i checked voltage at relay connector and got 0.15 volts and no juice at the horn and the fuse is good. did a search but couldnt come up with anything. any tips would be appreciated.

 

Make sure the horns are grounded.

 

checked it out last night and found a blown fuse and one bad horn. the blown fuse wasnt the horn fuse it was the tail lamp fuse. replaced it and got power to the relay. lesson learned... dont just check one fuse check them ALL.
