Back in January, I replaced all my solenoids (a couple had locked up, and in for a penny...) and the control panel, and everything was hunky dory for the two weeks I ran the system putting in the winter grass.
I recently decided to overseed again with a new seed, and now the system won't turn on any of the solenoids.
I checked the panel, and it's passing around 28-29V at each zone terminal when I activate that zone, just as expected.
I pulled a solenoid, thinking they had died again, and it tested fine when I applied power to at the control panel.
Going back to the irrigation valve end wiring, the solenoids I tested are only getting 9-10V each from the wiring. I tested them all, and they're all receiving around that voltage.
What am I missing? If it was no voltage, I would suspect a wire break.
