4-Zone Sprinkler: Zone 3 Dead, System Cycles Endlessly

Zone 3 No Water, Controller Loops Forever: Programming or Solenoid

Replaced Toro timer, both problems persist.

Endless Cycling = Programming Error

Multiple start times stacked. Clear all start times, set ONE per program.

Zone 3 Dead = Solenoid or Wire

• Test voltage at controller Zone 3 terminal (should be 24 VAC).
• If voltage good → bad solenoid or cut wire at valve.
• If voltage bad → controller output fault (unlikely on new timer).
