Ferrari Mailing List: Probable explanation for my horn problem!

[Michel Savard (mysavard]

Today, I decided to check the fuses. I tested a couple of relays (0332019151) 
yesterday and all were good.
In april 2023 I put the Birdman’s fuse boxes in. I just noticed the #16 (horn) 
was quite loose. It was easy to push it up and down. Still a bit tough to take 
it out but can this have been the problem ?
#17 (right fan) was quite loose too. Both fan worked yesterday by the sound of 
it, I didn’t check if BOTH worked.

If this was the origine of my  problem, meaning horn not working only when 
engine running, how do you get these things tight ? I tried with my thumb 
finger nails, but to no results. I couldn’t find a tiny enough screwdriver 
blade.
Any ideas ?

If that was the problem, now I only need to figure out the mess I made with the 
ground wire attached to the horn button.
