I have a 2003 TMZ-34 trailer mounted lift. After last use the outriggers would not retract. The boom functions normally and there are no fault codes displayed. There was some damage on outrigger wiring so a new outrigger wiring harness was installed. I’ve tested the limit switches on the boom (4) and they are good so the unit knows the boom is stowed. I’ve checked the switches on the outrigger pads and they are correct. I’ve tested the coils on the outrigger cylinders per the service manual and they are good. I’ve tested the coils on the outrigger manifold and they’re good as well. This unit has blue circuit boards and automatic hydraulic leveling. Overlay decal type buttons on the control box. Inside the ground control box the connection board on the back has two green LED lights. One labeled E Shutoff OK is illuminated. The other labeled Outriggers OK is NOT illuminated. I find no reference to this Outriggers OK light in the service manual. The light not being on indicates a problem. But what problem? There is no response when the buttons are pressed to move the outriggers and no power sent to the cylinder coils while buttons are depressed. Any suggestions will be greatly appreciated.
