OBA pressure switch not working?

I just put a compressor in my jeep with a 1.5 gallon tank and it works great accept the auto shut off doesnt work. It will continue to build pressure way after 135psi wich is what its supposed to be set at. Iv adjusted it and the wiring looks to be all right or at least the same as the little factory diagram on the back of the switch housing. Anybody have any ideas why its not working?

Thanks

I know I double posted but I wasnt getting any responses in other tech and I dont really know where this should go in the first place. So I thought I would try here.

Also Its SoCal Chapter, Cant we just post anything here?
