Toro EL-6A Controller Replacement Leads to Total Failure – Pro Diagnosis Needed

Old Toro EL-6A had timer motor issue and two zones weak. New controller installed—now nothing works. Zones operate manually at valves.

Likely Electrical Issue

• Wiring damaged during valve excavation.
• Controller not sending 24VAC (verify with meter).
• Common wire cut or disconnected.
• Transformer faulty.

Recommendation

Hire irrigation professional with pressure gauge and volt/ohm meter. On-site diagnosis is essential—too many variables (hydraulic + electrical) for remote troubleshooting.
