Rain Bird RC-7A Station Overlap: Controller Port or Valve Fault?

Station 4 Stays On Until Station 5 Shuts Off

This symptom suggests either the controller’s station 4 output is stuck on, or the valve 4 solenoid is receiving voltage from the station 5 wire.

Run station 5.
Measure AC voltage at the controller’s station 4 terminal (red lead) and common (black lead).
~24 VAC: Controller port 4 is damaged—replace controller or move wire to a spare terminal.
0 VAC: Problem is at valve 4—replace its solenoid or the entire valve.
