Fuse flashes when sprinklers goes on. Not all the time but approx. 50% of the time. Brand new pump start relay by Hunter products. Turned breaker off to pump. Still fuse on display. Disconnect common and zone wires from controller and ran a temporary wire to pump start relay. Still flashing fuse. Unplugged controller and unplugged everything that i could find on that circuit (including the freezer) and still same results. Also tried a new pro c controller and still had the same results. Only way...
