Question
Stations 1..3.and 4 operate OK, #2 just fails to go on..any suggestions as to what could be causing this....are there contacts that would have to be cleaned, if so, how??..Thanks for any help...MATT

Answer
Thanks for your question.
A simple test would be to reverse the wires on 2 and 3 terminals in the controller. If zone 2 then works on terminal 3, your controller is the problem. If zone 2 doesn't work, then your solenoid is bad or the wire is cut.
This will give some help as to what repairs are needed.
