Watermaster 57161 Won't Start: Check Fuse and Solenoid Shorts

System Stopped After Last Station; Won't Start Auto or Manual

Red light on (lower left)? → Blown fuse. Replace fuse (spare on door).
If fuse blows again → shorted solenoid. Locate and replace.
If fuse OK → measure voltage at each zone terminal (red lead) vs. common (black lead). Should be 24 VAC+. No voltage = timer or transformer damaged.
