I have a hunter sprinkler system for my lawn. One day it was working great, the next it won't turn on. I set the controller to 'manual all zones' and turn it on. The display shows its running, but the sprinklers never come on and I never hear the pump start relay click like I usually do. I have checked all the breakers and nothing has been tripped.

Is my pump start relay bad? Is there a way I can manually force the pump on or troubleshoot the psr?
