I need help. Changed a drive motor. Installed new hydraulic charge pump. Installed new control valve plus coil. Installed new main controller. Installed new case drain filter. New hydraulic fluid.
Brakes are locked. No bucket lift or tilt.
All lights come on. Start engine and runs a few minutes then shuts down. Belt is tight and pully key is not sheared. New battery. All fuses good.
Only thing i have noticed is the green wire from main controller supplying voltage to valve coil is 5 volts....
