Why is my Nelson water sprinkler backing up? - Nelson Garden

SOURCE: nelson lawn sprinkler timer will not turn on

Assuming that you have AC power (the symbol is not on to tell you it isn't failed), and everything else seems normal, then open it up and make sure the ribbon cable didn't come out (sometimes temperature variations make the clips creep apart and do weird things), and that the sensor connection is secure (either jumpered or connected to the sensor input). Look for corrosion or water in the box. Do you have electronics repair skills? If not, the best you are going to do is replace the main components until it works. The replaceable parts are listed in the manual (the front panel seems to be working, leaving the ribbon cable(not likely) and the main board.) You also have the possibility that some of the valves were fried by lightning or something, and possibly the drivers in the board.

I* am certainly not an expert repair technition but I do own a Nelson traction sprinkler and did the following to mine.

I've not checked but I doubt seriously that the transmission is only ten dollars and I doubt if you can spray oil into the axles that it will last very long. The transmission is plastic and nylon and surely gets brittle over time so do not go nuts forcing it. The transmission is held to the casting with hexhead slotted screws. I did not even try to loosen them with a screwdriver as you will only strip the slots-use a socket wrench-they are surely stuck. With the bolts out the transmission is easy to remove. I could open the case about 1/4 inch before it would not go any further. I think you need to remove the part onto which the T shaped piece that the arms attach to. My sprinkler is quite old and I did not want to disassemble too much so with a clean dull old knife it was easy to apply marine waterproof grease to the gears and the axels. I then, reinstalled the transmission and hand turned the arms in both high and low gear to distribute the grease.
I works fine now with water and should last for another 20 years.

I just took mine apart about a week ago. If, I recall correctly, you broke the T piece. That black plastic or nylon nut that is still connected to the transmission should thread off fairly easily.

I expect you can buy the part from Nelson.

If, solution #1 is correct and you find you cannot get the part, I've done some truly amazing repairs with that epoxy product called PC7. Depending how much of the part is broken and or missing, you might find a combination of what you have plus a brass T fitting plus the PC 7 will get it working.

You have nothing to loose.
