[QUOTE="TriHonu, post: 77432, member: 897"] Are you absolutely sure you put the wires back on the correct solenoids? If you mixed them up, you could have a set of wires from the Aux attached to the main hydraulic solenoid. Without engaging the AUX controls, one set of the three should have voltage when you are in the seat with the seat bar down. That set must be connected to the solenoid for lift/tilt. If one of the connections for the Aux is connected to the lift/tilt solenoid, you would only get lift/tilt functions by engaging the appropriate Aux function. ---------------------------------------------------------------------------------------------- The box that controls the aux hydraulics is the Pulse Width Modulator (PWM). [B]If the Aux control wires are connected to the Aux solenoids and the Aux is NOT working:[/B] You should check the connections on the module as well as the PWM fuse in the fuse block. I would also check for aux function in both momentary and constant flow modes. Activate momentary flow and try the RH middle rocker switch. Activate constant flow and try the RH trigger switch. If neither works, odds are the PWM controller is bad. If one works and the other doesn't, you probably have a bad switch or broken wire to or from the switch. [/QUOTE]
