Cat 420D return to dig

2005 BLN11341. Return to dig stopped working. There is no move movement of front bucket when the pilot joystick is moved into the return-to-dig position from a dumped bucket. Fuse has power. I was in some brush, but I don’t see anything obvious when looking under the machine. Thoughts?

    Just figured out there is a solenoid on the valve body. I’ll start there.

    Reseated the plug on the solenoid, and tapped on it a few times. Return-to-dig functionality is back.
