Ok guys, I'm asking for some serious suggestions here. My irrigation setup here at the GC is an ESP 16LX someone installed fairly recently to replace two RC 12's and 4 remaining RC 12's Two of these RC's are acting like they could give up at any time (advance motor runs slow, hangs when turning manually; nice LOUD grinding as they run, etc.) My sprinklers are setup in banks of 4 valve in head RB51DR rotors PER zone. Factory new, the 51DR has an inrush usage of .43amps and holds at .23amps. The RC's were rated for 3+MV or 4 valves per zone (2.1 amps with circuit break at 3 amps). Now that the RC's are discontinued, what controller out there will fire 4 solenoids consistently? Realize that these are not new either. A majority of these solenoids are mid 90's for date code/install. BTW, the ESP is running my greens and tees and only firing one and in a few cases two solenoids at a time. The other four clocks run fairways.
