if you have 24 Volts AC on solenoid and the valve does not open, but opens manually, then the valve diaphragm is bad. You can test this by swapping wire at timer with a known good one. If the known good one will not open valve, repair it or better replace it.. I have found that buying a new valve and swapping parts is cheaper than buying individual parts. If you decide to replace diagram when reinstalling screws place screw in hole and turn to left, you will feel screw rise up and then fall, this is position you need to in as the screw will back in the original threads and not cut ones. do not tighten screw fully down and repeat for the remain 5 and the tighten in criss cross pattern
This question has been asked before without anyone providing a link to a manual. My search only turned up 3 fraudulent sites claiming to have a manual, for sale, but my years of experience with similar sites made me avoid getting deceived.
The free youtube video below has a comment that it helped someone who had a Nelco 344c, so it may be of help to you.

Feb 14, 2013 ...Ricky Nelson. Long before Justin Bieber or even Ricky Martin, there was the original teen heartthrob. His name was Ricky Nelson. Nelson began his ...

Jim Reeves had more to do with Bimbo than Ricky Nelson.
You can Google this and get an answer.
My wife is a Ricky Nelson fanatic and she says absolutely no way he recorded Bimbo Bimbo. She has all of his records, albums, tapes, CDs and song lists.
Maybe water pressure available is too low for sprinkler's rating How do you get the sprinkler to turn When turn on the water the arms do... Nelson Sprinkler 3 Arm Square Pattern Wheeled Base Whirling Sprinkler How do you get the sprinkler to turn When turn on the water the arms do...
NO!! Never drill holes in any sprinkler system as the size and shape of the holes are very carefully worked out to give you the best cover. Check that your system is running at the designed pressure. This is all important as if it is too much or too little the pattern delivered will be wrong and not efficient. Small holes and high pressures waste water by evapourating too much and cost too much energy to run. Low pressures can result in big droplets which carry well but may over shoot or undershoot the desired path. The most efficient distribution graph of any irrigator is designed to work within relatively narrow parameters.
You really should consult a qualified irrigation technician.
Just a WAG, but My first suspicion is your internal battery has become very weak. It's down low and behind the control panel. Similar to a smoke detector when the battery is getting weak. Hope this helps!
