I looked at the two o-rings in my axle shift switch. They looked good, so I cleaned and oiled them, put it all back together now. Just going to have to wait on the pressure switch before re-installing it. Found out today that my low air switch didn't work either, it was stuck "closed" all the time. The last owner had un-plugged the low air buzzer, I plugged it up, and it worked once, and I guess it burned out or something. Never could get it to work again after that, even on the work bench connecting it to direct power source.
So I thought I would check the brake switch while I was at it, and found out I had a hydraulic brake switch... the hard way. I think you seen my post on DeucesWild's thread.
So, I've got 3 pressure switches to replace now. At least I didn't place my order this morning until I knew that I needed all 3 of them, so I got them all on order. Should be here monday I guess, and get this thing back together. Been working on this truck for the past 3 months now, Going through everything. Going to make a new thread to show it all once we get everything completed.
Thanks!
