   I have a series of heads out of Toro newtwork vp . Stations 1,2 and 3, all come up and run.. when you turn station 4 -6 ( on the same pipeline) station 4 will come up for about five seconds and then will go back down. Station 4 5 and 6 will pin on individually and triac from station test. However when you try to run stations 3-6 , 3 will come up , 4 and 5 will not come up unless you pin 3 off then 4 will come up for a few seconds go down, and 5 will come up.
   Think it is a voltage issue with a bad solenoid in the field. Just trying to get some thoughts , feel free to ask more particular questions if need!

   Hello Austin, I have Sitepro LTC + . It sounds like a circuit board in sat to me. Have you tried switching good performing plates with the troublesome ones?
   
   Good luck Michael

   I have LTC+ Site pro. I had a very similar issue two weeks ago. Stations before station 31 would only work intermittently and rarely at that. I had resistance at stations solenoids 1-31 but they were fluctuating. I found low fluctuating voltage at station 31. Perfect voltage at station 32. I do not have a wire tracer or ground fault locator so I bridged the common wire from station 32(working perfectly) to station 31(working intermittently) in the field. This fixed the issue and I trenched between the heads buried the jumper wire and put it on the map....Done! I suspect a repair was made at some point and not put in a box or on the map. We found a drain line not on the map. I believe this was added to help drain a near by low area. Repair splice not in a box and tree roots don't mix. Hope this helps. I would look to a short in the common. If you have a bad connection you may get enough voltage to start a head 14-15 volts but not enough to hold the solenoid open or run other heads.

   I'm thinking Thomas has it pegged! Its usually a problem with the common when trouble shooting with this type of problem.
