I replaced the Norgren air valve and it didn't fix the problem. The slide still will not close. When I changed the air valve I just switched over the old fittings and reattached the air lines. Are there any other adjustments that need to be done to the air valve, or do I need to start looking toward the electrical side or the actual air ram. I am hoping it is not the ram since it looks like it will be a pain to change out. The small box on the top right corner looking at the air valve came new with the new valve and it looks to have a few adjustments, but I don't want to mess them up if they were set up correct from the factory.
I also saw no signs of water in the air lines or tank, and the air dryer cycles regularly so I think I as good there.
The green air gauge will also start to leak air within 24 hours and will settle and only hold air at around 5 to 10 psi, while the orange needle will hold over 60 psi for a month or more. I haven't been able to find where it is leaking.
Does any one know a good way to test out the electrical side of the step cover. Looks like a red wire to the front top terminal, and 2 black wires to the top back terminal, then a black wire underneath on a lower terminal. I am guessing red is positive, two blacks are triggers, and lower black is the ground?
Thanks Carl
