Orbit Timer Zones Cycling On/Off Every Minute: Electrical Testing Procedure

13‑Year System, Orbit 6‑Station (5‑7 yr); Zones Run 1 Min, Click Off, On Again

Systematic electrical tests:

1. Reset the timer.
2. Test input voltage to the timer.
3. Test voltage at the controller terminals for the affected zones continuously for >1 min to catch the dropout.
4. Test ohms on the zone wires (check for open circuits).
5. Test voltage at the valve solenoids.
6. Inspect all wire connections for corrosion/looseness.

Report findings for further guidance.
