What's the best way to diagnose? Just start taking things apart?
I took the control valve apart, and the spool looks fine. When blowing through it, air seems to go where it's supposed to.
I know the return after the diverter valve must be working fine, because it's common with the FEL return and the FEL controls work fine.
Any idea why the dead heading would happen only when returning the control to center from contracting the ram, and not from expanding it? That's where I"m really stumped.
If the splitter control valve works fine, and the FEL controls work fine, the problem must be either:
[list] a) In the ram itself b) in the hoses to and from the diverter to the splitter valve c) in the coupler d) in the diverter valve [/list]
I guess I'll just work through them all, starting with the coupler, then the diverter valve.
