Lift Axle Valve Question...

[Waterloo]

I found it, up near the cab on the crossmember. I think the issue is the air solenoid... I checked the wiring in the cab, all good. Checked the relay, working. Chased the main power to solenoid, I think that is the issue, the solenoid. Ground appears good. Still need to test.

And that is the thing, I think it is just that solenoid that is bad. It is an always closed unit, looks darn near identical to the one we use on our fan clutch. I believe the valve is fine, so looking for a solenoid, FleetPride may have a universal unit, I guess I could Mickey Mouse it in there and make it work.
