Looks like my horn circuit was on for a while, I have the horns unplugged at the front so I never noticed, looks like it killed the battery for being on for so long....

I think I’m missing some rubber washers/grommets that sit on the plastic guides that allows the ring to move up and down when you tap the horn.

I think the part number is 48441-12905 which looks like NLA. Anyone have an alternative, whatever the hardware store has? 
 

 

 

I ended up using some 3/8 grommets in this location, I don’t like how they fit. They appear to be too thick to tighten all the way down and have enough play to get the horn pad installed on.

 

will keep looking around for a solution.

on the plus side the horn does jot randomly turn on.

Ah I went back out in the cold and cut them down in half. The total thickness is 5mm, works great the pad fits snug, and the horn is not on randomly.
