John Deere 457 baler gate

I am working on a 457 and the gate indicator started showing the gate open when closed. I put a new microswitch in and adjusted it and it still shows the gate open. When open the gate open shows proper and no problem but as soon as it closes it starts beeping and shows it still open. checked wiring and connections and seem good .

Mine did that so I changed hydraulic hoses to different scv and now chamber alert doesn't sound and blink.

Brother broke a hydraulic hose the day before so it may have air in the system I will check that thank you.

Today I bled the hydraulic lines, wired the connectors at the switch, replaced the connectors on the switch. Switched the hydraulic lines to another scv. no change . I talked to the service manager at JD and he said that single switch controls the monitor so it has to be a broken wire.
