Title: Broken Horn Switch
Post by: Timmy Tucker on December 05, 2010, 08:34:43 AM
Due to the bike being dropped by both myself and previous owners, the horn button is smashed into the control housing and no longer works. I was wondering if anyone had successfully repaired a broken horn switch? I can't afford $200+ for a new set of left hand controls, and can't seem to find a used one w/o the same problem.

I generally have no qualms about tearing into stuff to try and fix it, but I'm a little hesitant to tear the controls apart and possibly fubar the whole control assembly. Anyone have experience with this?

The horn switch contacts are held in position by a tab and a screw, if the button is pushed *hard* the tab can pop out of the slot in the housing.

Some times need to straighten out the contacts as they can get bent in the above scenario.

Requires a bit of fiddling around with small parts, and a good small phillips screwdriver.

Well that was easy. Took about 5 mins to disassemble, fix and reassemble. Thanks!

just fyi for those that got here from searching as i see you already fixed your issue

i've been having some issues with the horn switch myself. after tearing into it, i realized that the contact plate the button makes contact with moved further away from the switch.  now the button no longer makes contact due to a further distance if this makes sense.

to correct this, i had to shove some neatly folded electrical tape behind the plate to prevent it from moving away from the button.  works 100% of the time now

As a reference point, I've disassembled the horn switch on the 1998 ST2 that I used to own twice to fix it.  (The ST2 used the exact same switches as the Monster.)  The first time it stopped honking the horn and I opened it up to clean up the contacts a bit.  The second time it was at the point where it worked most of the time, and I pushed the switch too far in while trying to honk at some moron on a cell phone who cut me off and was totally unaware of what was going on.  I had to bend things a bit and use a file to clean up the contacts to get the best operation.  Hopefully the new owner of that bike has no further problems with the horn.
