Air horns are leaking.

Is there a way to adjust them? Or will I need a new solenoid or similar?

leaking air? or just staying on blaring the whole time? Check the diode going to them if they are staying on. It has been a problem for others. Should be located right near it. If it is staying on then it is something on the ground side as it is suppose to have 24+ all times when the switch is on.

If the actual tubes are leaking air replace it with a louder unit

They are not blaring. More like weeping to a tone and getting slowly louder. If i stick a rag im the top hown or cover the hole with my hand it stops, but i hear air escaping.

Take the air line off going into the solenoid. Put some oil in there. Reconnect it, and cycle it a few times. The seat in the solenoid probably just dried up or the pintle can’t fully seat due to rust or a foreign piece. Lube may help it.

I'll try that, thank you

So Ive undone some fittings and removed the solenoid and opened up the botton, which would let me look at the plunger of the solenoid. I saw that a piece of metal got lodged between the plunger and brass opening. I put a round piece of flexit tape. Put it back together and the horn weep is gone.
