Hey guys.... As the header says.

Our Terex TL100 loader has lost its aux hyd function.

The control switch in dash is a momentary switch that turns on or off the circuit. ( Momentary tap one way, aux function ON. Momentary tap other direction, aux function OFF )

Switch swapped out with FLOAT switch ( to verify good or bad switch ) Still no aux oil flow ( from tilt cylinder to aux hoses )

All fuses good.

Do any of you happen to have a wiring diagram for this unit?

Hi, Did you solve this ?
Well yes. Sort of... I ended up hardwiring into the auxiliary control valves and running a new switch. Temporary until I can get her in, to repair properly. I found it was faulty trigger buttons in the joystick.
