[OCCRA]: Problem with the compressor, pressure switch, or Bosch relay.

[BrittanyV]

OK, I cannot figure out this problem and I have been working on it for more than a day and a half. Our compressor will not shut off at all. I've read the manual about ten times, and I have everything wired properly. I'm actually an electronics person (our last pneumatics person graduated and we can't get a hold of him) and I have tried everything that I can think of. The only thing that I am not positive on is what wire of the pressure switch to connect to the positive fuse block and which to connect to the white wire on the relay. The wires are brown and blue, and I've tried both ways. As far as I can tell, everything in the pneumatic system is hooked up fine. Air goes in all the right places and everything follows the diagrams and instructions. I've replaced the pressure switch and everything. I cannot find any leaks in the system, so I don't believe that's what's causing the problem

If anyone has any idea on what the problem could be, I would be so grateful. I've worked on this for far too long and I'm getting behind in everything else.

Thanks,
Brittany
