All,

My neighbour has found that the sprinkler system in our garden is no longer working. I'm not familiar with it, but a quick look seems to show a wire has come loose (see the cap lying at the bottom) - however, I'm not sure which wire is which before putting it back! Can anyone identify as to what I'm looking at here? I've attached pictures both of the controller, and what I assume are the pumps.

Thanks,

Neil
