Just finished my install of 4 zones run off a shallow well. 3/4hp jet pump with a pump relay hooked up to my nelson controller. Has been working great for the past week. Now zones 3 and 4, the valves don't open (rain Pro 8410t jar top valves). I've checked at the controller and each zone gives off 24 volts (when the controller send the voltage). At the manifold (50' away) both zone 3 and 4 have power and i can hear the solenoids. I've taken apart the valves and nothing is restricting them. When the solenoid is activated if I manually open the valve a bit then close it the solenoid seems to hold open the valve. valves 1 and 2 work perfectly. i can't figure out what is going on. everything is brand new. thanks
