Hey group, I'm having issue with 15 zone sprinkles that when either on auto or manual start, each zone doesn't come on, but the water trickles from all the the heads that I can see. I have a master valve that I opened manually, thinking it was it but no change. I disconnected 1 module and even tried flip floping them and no change. I tried using a 6 zone Hunter X-Core ( just to see if it was the controler ) and connected the common, MV and 1 zone wire and the water still trickled out of all zones. Im stumped and I really want to DIY it. Any help would be appreciated
