Hardie Rain Dial Won't Activate Sprinklers After Rain Shutdown

Symptom: Controller On, But Valves Don't Run

After being off all winter, a Hardie Rain Dial shows display but won't run valves manually or automatically. Manual valve operation works.

Verify controller power: Remove battery; if display stays on, AC power is good. If display dies, check transformer/outlet.
Test controller output: With voltmeter (AC 24V scale), touch black lead to Common terminal, red to Station 1 terminal while manually running Station 1. Should read 22–26 VAC.
If no voltage: Controller is bad.
If voltage present: Check voltage at the valve solenoid wires. If missing, field wire is cut. If present, valve solenoid or diaphragm is bad.
