zone came on and it was not scheduled to
nelson projr 8304 brain. This morning zone 2 came on and it was not
scheduled to. I changed the solenoid but that did not fix the problem. I
changed the diaphragm but that did not fix the problem. I disconnected
the zone wire at the brain and moved it to another zone spot. The zone
did not activate so I switched the zone wires around and any wire I
connected to zone 2 immediately turned on. I do not know what is wrong. I
am thinking I have a bad spot on the brain and zone 2 position is
sending bad information to thee solenoid.
