Hunter Pro-C Shows Running But No Water: Test Controller Voltage Output

Manual and Auto Show Running, But No Sprinkler Activation

Water source is on. Need to verify controller output.

Test Procedure

  1. Run Station 1 manually.
  2. Measure voltage at controller: terminal #1 (+) vs C/common (-). Need 22–26 VAC.
  3. Voltage good: Check for Master Valve (MV) or Pump Start (PS) wire on terminal strip. If present, master valve may be stuck closed — locate and repair.
  4. No master valve: Field wiring to valves is damaged — repair or replace wires.
  5. Voltage low: Controller defective — replace.
