Hey Kent, at this point I would swap the valve assemblies complete with the solenoids attached and see if the problem reverses itself. The pins Edward is talking about that aligns and holds the solenoids on place is on top of the case. It takes an 11 mm wrench to remove each one and then slide the valves out. They have a rather tall hex head, below that an oring, and then a pin about an inch long that engages a hole in the far end of the valve. As I recall, I used a 1/8" welding rod piece about 2" long with the flux removed as an "alignment tool". Keep us posted!
