24SSRCXP Pontoon horn not working

[pbock]

I have 2017 Bennington pontoon 24SSRCXP and the horn is not working
I checked the switch, and circuit breaker both are good, replaced horn and still no luck
Looks like the wiring goes through a wiring harness
Any help on locating wiring diagram of wire harness

The Electrical Specs thread in this forum has some schematics. I didn't see any specific to your model, but the horn circuit doesn't seem to have changed much. Best option is to start probing with a meter to see where you lose the 12 volt reading. Also, make sure to verify that the ground side is still good.
