Why does the fuse keep blowing in my Irrigation Controller?

Field wiring from the Irrigation Controller to the Solenoid Valves may need to be checked

The single amp glass fuse is installed in the Irrigation Controller to protect the board from being damaged as a result of something wrong in the field wiring to the Solenoid Valves
If this fuse has blown, check that the wiring on each STATION is intact and not damaged
If your fuse is continuously blowing, remove all wires from every STATION and reconnect each station one at a time to determine which STATION is causing the fault
