air valve issue
Hello. i have a 2012 ftl cascadia with no air to the accessories. cannot change from low to high range, no cab air bags, no seat air, no differential or anything else. brakes are fine and tractor airbags(suspension) is fine. primary air guage shows 130 psi but secondary guage shows 0 psi. just put on new air dryer about 3 weeks ago(the one with the governor mounted on the side of it, bendix ad-is model). main air compressor was changed last sunday at a ftl dealer in Ms. after the other had busted the housing. I have no air in the wet tank, but do have air in the primary and secondary even though the secondary shows zero on the guage. what valve should i be looking for? i figure it is a faulty relay or check valve; i just don't know where. any help would be greatly appreciated. thanks.
