Did my once a month start up and was checking everything and the airhorns would not work. The car style horns work and I hit the horn button several times however the airhorns would not sound.
I seen on Nick post that he had problems with his airhorns because of a bad or poor ground.
Where is that ground wire located?

Thanks, Jim

I forgot to add the following info for everyone,

Jim, on my coach the bad ground was located at the solenoid that is mounted on the firewall. Roll out the generator. Just to the drivers side of center on the firewall is the solenoid that operates the air horns. You can identify by the air lines connected to each side. Ground just went to a ground buss higher on the firewall. Now having said this realize Barth did them all different. Hope this helps.

Thanks Nick,

It will give me a place to start looking and like you said almost every Barth is just a little different.
