I can't get my compressors to shut off...

I have Seige Engineering horns and now they are out of business! I had them installed on my 5th whell and now transerfing them over to my Chevy truck. I need a wiring diagram please. I can’t get the pumps to shut off. I had them working on my 5th wheel but I can’t get them to work now. I am installing them the same way as I had them installed before. THANKS!!!

could you just put a toggle on the power wire?

That is how I had it hooked up. I just need a diagram. I must be missing how to hook it up to the pressure valve…

I have a power wire, ground wire and a blue wire coming off of my compressor.

My instructions are not clear. But I installed them on my 5th wheel ok and now I am lost…

Someone HELP me PLEASE…

power wire to the battery with a toggle and fuse connected. ground the compressor. and for the pressure switch you have the ground and thats going to a 12 volt source too and the compressor i believe i dont quite remember. I think thats how mine is set up. you sure you just dont have a bad pressure switch?

use the pressure switch load wire to power your compressor… if it fails to shut off then, request an RMA since the pressure switch you use should turn itself off

opps I never saw this thread, I just posted up almost the same thing…lol

SOUNDS like the pressure switch to me also…mine has done that before several times…run and run, and when my tank pressured up to 275psi I knew the switch was done !
