I have a late T190 ser. 531615995 with intermitant "no hyd.and drive" when working code is none when not working ACS light is on with codes: 32-04 ACS not comm. with bobcat controller 75-04 no comm.from drive controller 39-16 left joystick not connected 40-16 right joystick not connected I have wiring schmatics and was doing pin-outs for powers and grounds and noticed voltage was a little high 15.1v I unplugged alt. so now volts is about 12.2v but still "no hyd.and drive" and same codes I changed the ACS controller a couple months ago for a "no drive" issue and put it back now to test but still "no hyd.and drive" and same codes I now put back the new ACS controller. It seems if it sits over night it will work for awhile. any ideas wally 808-479-3323
