Rain Bird ESP-ME "Station 1 Wire Shorted": Solenoid or Wiring Fault

Error Indicates Short on Station 1 Circuit

Main lawn zone skipped; other zones work. Error: "STATION 1 WIRE SHORTED".

Quick Isolation Test

At Zone 1 valve, cut one solenoid wire.
At controller, run Station 1 manually.
Error persists: Short in field wiring (controller to valve). Repair or replace wire.
Error clears: Solenoid is shorted. Replace solenoid.

Why This Works

Cutting the wire at the valve disconnects the solenoid. If the controller still sees a short, the fault is in the wire run. If the short disappears, the solenoid coil is internally shorted.
