I'm hoping somebody can point me in the right direction for troubleshooting this. I have a Cat 247b3 that starts and runs fine but I'm not getting any hydraulic movement from the right joystick. I parked the unit with everything functioning but now nothing from that controller. I only have the operation manual so I'm sitting pretty blind here. I've confirmed that the hydraulic oil level is normal and that the hydraulic lockout switch is not engaged. The unit does not have an enclosed cab with a door so no door switch. All warning lights seem to be functioning and there aren't any warning lights indicating a problem. Serial number is: CAT0247BLTSL01277
