Toro ECTRA "Fuse" Flash on Zone 2: Internal Breaker Tripped by Shorted Solenoid or Wire

No Physical Fuse — Internal Circuit Breaker

"Fuse" + zone number means overload on that zone's circuit.

Diagnosis

  1. Disconnect wires from Zone 2 solenoid.
  2. Run Zone 2 from controller.
  3. "Fuse" still shows: Field wires shorted (hot touching common).
  4. "Fuse" clears: Solenoid shorted — replace it.
