sprinkler system zone not working

My system is 7 years old....now zone 1 is not coming on. I checked all the wiring in the control box, and it looks great. I then went to the zone valve box and checked the wiring, which was corroded and gross where they twist together underneath the nut. I cut the wires, stripped off plastic to expose fresh wire, and re-wired everything in the box. Still nothing. So then I went and bought a new solenoid, and replaced it. Still nothing when I turn the zone on.

If I start unscrewing the solenoid, the zone will come on - but I have to screw it back down to get it to shut off.

Any suggestions about what to do next? Thanks !
