I have one valve that's not working. The positive wire is hot with 27 volts, but when connect the lead to the valve, the voltage goes to nothing. I borrowed the positive wire from an adjacent valve and it worked. I know it's not the timer (I swapped zone 6 & 7 to check it), I know it's not the brand new valve, and I know it's not the common wire. It has to be the positive wire, but I can't figure out why I get 27 volts until there's a load on it.
