Electrical Troubleshooting for Irrigation Systems

Students will be introduced to the basics of electricity and how it applies to irrigation systems. Multi-meters will be utilized in taking voltage and resistance measurements in class. Typical irrigation system electrical discrepancies will be presented with possible causes and solutions in addition to tracking buried wires and valves and isolating wire faults. Topics covered include:

  • Basic electrical terminology
  • Multi-meter usage at the controller and in the field
  • Wire splices
  • Wire tracking
  • Fault isolation
