Hey everyone,

I'm struggling witch a Iteco scissors lift. It has a Curtis 1243 Controller and we get the fault code 1,3. Which I can see on the LED on the controller. We bought a brand new controller but the fault didn't disappeared. The manual says: Bad motor wiring or the M- and the B- terminals are short. The motors work perfect when I give them power directly. Between the M- and the B- terminals I measured 1-2 Ohms when it's powered on. When I shut off the power this resistance goes up to 80-90Mohms. I also tried to give signal to the pins directly what the wiring diagram says. This 1,3 Code is also shown when there's no wires on the high current terminals. What's the solution? This machine is very important in our company, so i would love to fix it somehow. Thank you.
