Sprinkler help. Why does one section keep going on when the others do? Details below

I have 7 zones. I prefer to do the sprinklers myself because I can and I have the ability. Any major repair I would find someone.
I have one section running on a hunter node. Kind of a cope out by a past technician but it is what it is.
This one section pops on every time I turn another one on. I am thinking a valve type thing? Not even sure where the valves would be located maybe near the node?
Also I took the batteries out of the node to try to just shut that section off and the damn thing still shoots water out of that section when I turn the other ones on. I am not mad about the water but kills my pressure to the other larger areas.

Your wiring is messed up. That valve has to be getting electrified to come on when the others do.
I’d guess the common wire to that valve is messed up.

Finding the valves is going to be the hassle. Hopefully they put the valves in valve boxes but you can start by taking a metal piece of rebar and going down the line putting it in the ground until you hit the lid hopefully. If you don't find it there, you can start at the water source and start poking around there.
You definitely have a wiring job that the past technician didn't want to jack with apparently.

Just so I get this right, you're saying that when you turn a zone on, the valve that is wired to the Hunter Node comes on at the same time?
If that is the case, its not a wiring problem because that valve is not connected to the control timer, it uses the Node to activate it. It could be that the valve has debris around the diaphragm and when the pressure changes by turning a different zone on the valve activates or the diaphragm could be worn out, it does happen occasionally.
It should be easy to find the valve with the node attached. The node should be directly wired to the valve, the wires are not very long (less than 12"), you should be able to trace the wires by hand to find the valve, it might require a small gardening trowel to dig the dirt from around the valve.
If the diaphragm is not good, you don't have to replace the entire valve which would require you to cut it out and do some minor plumbing work. The bottom half of the valve that is connected to the main water line and the sprinkler zone should be fine, all you would have to do is shut off the water, take the top cap off(should be attached with screws), and remove the guts. Unscrew the solenoid that is attached to the Node, leave it wired to the Node, replace the guts and top cap of the old valve with new ones (buy the complete valve and use the parts) and screw the solenoid back on and you should be good to go.
Replace everything except the Valve Body. You will not be able to use the new solenoid, it is 24v, the Node requires a DC latching solenoid so use the one that is already attached to the Node.
Hope this helps.
