Have a customer who I installed late last fall who is on their 4th timer. Everytime after a lightning storm the controller [Nelson] gets zapped! I checked all the valves and even rewired them to make sure of good dry connections and the customer even put a surge protector on the outlet where the controller is plugged into. Any ideas? Thanks

Also the controller is internally grounded so the manufacturer says there is no need to ground it with a rod. I have 2 houses within a block of this home [2 years old] with the same controller and have never had any problems.

check the connections on the outlet to make sure wires are tight, also check wire conections at breaker. Loose wires at these points can sometimes cause problems. Am I understanding that the surge protector didn't protect the controller? If you continue to have problems install a gfi outlet, it may be a pain in the a### but it should protect the controller and it is easy to reset

So you have replaced the Nelson controller everytime with another Nelson? Off the subject of lightning, I don't know how many Nelson controllers we have eaten :eek: We installed a bunch of them in a two year period and almost everyone of them was lost within a couple years.
