I have 7 stations on a Hunter I-Core Controller box. I have a wire that is reading 60 volts and the rest are reading around 24 volts which is what it should be since I have 24 volt solenoids at each valve. However, when I turn a valve on with the box I don't get any response? Also, I have left the wire that is reading 60 volts capped off in the box and I manually turn that valve on when needed. Anyone know what might cause this or what the issue may be? I'm thinking the source would be the wire ...
