I rebuilt the dana air compressor for some reason it decided to break again, the piston shaft broke. So a friend rebuilt it for me and it took me
awhile to get it back in. I was distracted by other projects. Today I put it in and it does not seem to stop just keeps running. I aired up the tank
with the shredder valve at the tank and just past the compressor. I re-read the rebuild instructions and still am not sure why it wont shut off. I do
not hear any air escaping any where. I can find no details to see if I wired something wrong, there is one wire I am not sure of.

There is a gray or black box that has a diaphram that sense air pressure
and opens up the circuit.
The diaphragm goes out so you need to replace it.
It is about $30, find it on our web site under Rear suspension.

Get a gauge on the system, temporary or plumb it in, and check the pressure. Mine doesn't cut off until 135 psi., according to the gauge I plumbed
into the system. Use soapy water to check for leaks you cannot hear. The power supply wire for the pump was routed directly from the pressure switch
from the factory, but your P.O. may have installed a relay in between them like I did to reduce the current load on the pressure switch and the power
supply buss energized by the ignition key. It is also best to run the engine while the compressor is on so it gets full voltage from the charging
system. Let us know what pressure you reach and we'll go from there.
