I recently added a thumb to my TB135. However, I cant get the aux hydraulic circuit to work. The buttons on the joystick don't seem to do anything. I should get a set of manuals. Am I overlooking something simple?
Check the switch wiring from joystick, i suspect maybe no pilot solenoid valve installed on the pilot line to control main control valve..
Thank you. I am suspecting the buttons on the joysticks... The rubber buttons have deteriorated from the allowing water to get in.
