Have Truck Repair Questions? Ask an Expert
Hi Chris, My name is***** will be glad to try to help. What is the serial number of your lift? It sounds like one of the safety switches is not functioning properly.
That is along the lines I was thinking. But usually they prohibit travel if the platform is up and uneven... Let me see what I have for troubleshooting and schematics
Hi Chris click on this link for the manuals, schematics, and troubleshooting info.
PDF page 94 says to test and check wires #71 and #19 from Terminal block 1 ( TB1) to Drive override limit switch ( LS6) for open circuits or loose connection or damage. I would test for continuity in the circuit using your OHM meter.
LS6 is the Drive override switch. Go to PDF page 55 in the manual for the schematic for this circuit.
