Live Streaming – Electrical Troubleshooting

Troubleshooting the electrical operation of an irrigation system is a scary thought for many professionals in the irrigation industry.  This training class aims to remove the fear of electricity by helping students understand how the electrical system works.  First, an explanation of electricity will be presented along with some of the tools necessary to work on the electrical system.  Electrical failures will be explored from both the power supply side and the irrigation controller operation.  Finally, discussion on electrical circuits including control wiring and valve solenoids will complete the troubleshooting of an electrical system.
