Rain Bird E‑6: Only Zone 4 Works – Common Wire or Solenoids

New timer same issue: only zone 4 works. Valves look normal.

Diagnosis

1. Check common (white) wire continuity to all valves.
2. If common good, test solenoids – replace one ($8) on a dead zone; if it works, replace rest.

Always shut off water before removing solenoid.
