Rain Bird RC-7Bi Stuck on Zone 1: Advance Motor or Switch Failure

Mechanical Timer with Two Motors

One motor keeps time and times zone duration. Second motor advances the zone turret. Zone 1 runs indefinitely; manual advance required.

If turret doesn't auto-advance after manual click → advance motor failed.
If it advances after manual click but not from start → top-back micro switch failed.

RC-7Bi discontinued long ago. Replace with Irritrol Rain Dial or Rain Bird ESP — compatible with existing wiring.
