Only one horn toots.

I have checked all the lines switched the wires around and even made a new ground. Only one horn toots until there is less pressure in the tank then it finally sounds like a loud fart after a bowl of chili. I like these horns. They are my second set but I don’t know where to look now. Could it be too much pressure or the solenoid is bad? Please help me with this. I hate having things that don’t work on my truck.

Have a blessed day.

Welcome to the forum!

What horns are problematic? What are the system components?

They are the outlaw horns that is 3 all connected together. I have a viair tank on there and the place I bought it from in Dallas said that it was 150psi set. No directions were in the box when I bought them
