Added a 3rd remote to my 8030. All 3 remotes work fine - but 3 point won't raise. What did I mess up?

By chance the draft lever got pushed all the way down during the process?

No action no matter whether draft is up or down.

Will it raise if you reach behind valve and push in on spool?

Did you remove the valve assembly or just add a valve? MACK

Did not remove the assembly - just added a valve. Did not try moving the spool by hand - did check and confirmed that the lever was moving the spool in - at least some - although it did not seem like it moved it very much. Will try moving the spool by hand in the morning.

The spool does move - but not as much as on my other 8030. The 3 point lever also creeps forward - so there must be some residual pressure - I'm guessing hydraulic rather than mechanical. I am also getting an intermittent hydraulic filter warning light that was not there before adding the 3rd remote. Is there a check valve of some kind in the 3 point valve? And can I get to it without taking the stack off?
