Machine starts and runs but when you push the hydraulic release button it releases the throttle but no hydraulics, pumps are working relays tested okay,
fuses are good. This is an interment problem but most of the time it does not work.
Found the problem the wire going to the lever lock solenoid on the sub valve was broken at the solenoid connector also the connector was very corroded giving intermittent hydraulic flow.
2017 TL12 R2. The battery went dead and I replaced it. The machine start and runs but hydraulic interlock switch will not engage hydraulics. Engine does not go into high idle.
