Sometimes a solenoid isn’t working because there is no power getting to it.
What to do?…
Firstly – check that there is power ‘leaving the control box’. Put the multimeter probe on the station terminal and on the common and the reading should be 24V+. If not then the problem lies there. (This does happen) Simply change the wire to an unused terminal and you should have power. Voila!
If there is power there then the break is somewhere between the control box and the solenoid. Depending on how easily accessible the wire is will determine what you do next.
If its possible to use a wire tracker then you may wish to go this route, but assuming most people don’t own one of these then the next best option is to look in obvious places for a break.
These are usually:
- at the base of control box
- by the solenoid itself
- anywhere the ground has been disturbed.
If it doesn’t turn up easily then you need to decided whether it is worth tracing from the box and testing at regular intervals.
If it a sole solenoid then you don’t have much choice, but if it is sitting next to another solenoid then you have two options.
a) wire the two stations together and run them as one – if there is enough pressure.
b) use an ‘add a station‘ device to act as the wire that was broken.
Option A is cheaper if you can get it to work as the ‘add a station’ modules come to nearly $100.00 for the part itself. However if this is your only option then its good to know you can use it.
