My horn did the same thing on my RK. Turns out it was bad, if you have a service manual you can test it with a OHM meeter. I called my dealer, told them and I picked up a new one.

Been fine.

I need a new horn

One that won't make me sick

One that won't keep me up all night

One that won't make me feel three feet thick

Sorry, just listening to some '80's Huey Lewis and I couldn't resist.
