Hydraulic Deflector not working

[PNWBXer]

BX2380 with BX2816 SnowBlower with BX2821a Hydraulic Shoot deflector. When I depress the installed switch on the box on the stick.....a diverter valve should work to allow the deflector hyd piston to work (aka stops rotating shoot and starts raising or lowering the shoot deflector. That isn't happening as depressing the switch does nothing and still allows chute rotation (vice stopping rotation and starting deflection)

Year 5 of having this set up and its been working great in that time period. I started troubleshooting and realize I might be in over my head as electrical stuff isn't my strongest suite. I guess my question is if there are any known issues with this setup and might be an easy fix? Don't want to drag this thing to the dealer as I don't own a trailer and it would be a PITA. I"m just trying to wrap my head around how the whole system is wired so that I might find what is causing the issue.

I would need to see the wiring diagram as there are several ways to wire up the 'system ... but... 1st possibility is a blown fuse. 12 volt from battery 'should' be going to an inline fuse that feeds the push buttons that power the solenoid valves. If that's good, #2 would be 'no ground'.

Others who have that setup can offer better help.

Mine has a plug in connector that connects a few wires to the valve (the part that’s stuck on the side of the loader valve). At about 400 hours it quit working in the middle of a grapple job. Somehow that plug had worked loose just a little bit. Unplugged it, plugged it back in. Fixed.

Intended to take a look at it after finishing the job to see why it might have come loose, but we all know how good intentions often end up. 200 hours later no further issues.

So maybe in addition to the above advice from @GreensvilleJay, which I agree with, also unplug and reconnect any electrical connection plugs in the diverter wire harness. For mine, that’s just the connector on the diverter valve and a connector at the button on the stick. (Edit: Yes, there are other electrical connections, but they’re not plug type connectors.) YMMV.

All the diverter valve needs is two wires- one is 12V and the other is ground. Start by checking continuity on the ground wire at the diverter valve to see if there is a continuous path back to the battery's ground. If that's good, move onto the 12V wire. If not, you'll need to find where there's an open.

While pressing the button, see if there's 12 volts on that wire at the diverter valve. If not, you'll need to move up the chain to find out where the 12 volts stops.

I don't believe there's a relay for that 12 volts but it all depends on how your setup was wired.
