Hi Folks,
I have been having EAS problems of late. On the way home from a trip down South the air bags started going down. After a while I found a place to pull off the highway and bypass the the control system and inflated the air bags directly to get home. On investigation I found a loose air hose under the bonnet. Easy fixed, but then the air tank would not hold air. The air bags were fine. Just as soon as I turned the motor off the diaphragm would open and dump all the air in the tank. I pulled the valve block and checked every thing in there and it looked fine. I did read somewhere that the diaphragm is held closed by the air pressure held in the line from the compressor to the valve block. I did replace the little O ring under the reed valve. I fitted a gauge in the line from the compressor and the valve block and it was holding pressure, but when I put it back to the vehicle it would dump all the air from the tank. So I got a inline non return valve and put it in the line, and it still won't hold the tank pressure. So at that point I gave up and went to the shed to work on another project. I will try again tomorrow. Does anyone have any ideas of something that I am missing.
Thanks for any advice you can give me, Regards, Alan
