Did you solve the problem?
In the initial message you wrote that you have error 1307, now you are writing about error 1317. Error 1317 signals that the engine temperature is too high. Most often, the wires break right after the plug at the temperature sensor. The external insulation is normal, but there is poor contact inside the wire. Pull each wire with force, you can do this with the car on. A broken wire will give an error.
Change the contractor and the battery cables and harness. Working well and Controller output voltage L1, L2,L3 12V. When moving 11V. After a while E1317 error message appears and stop working. When switch off and switch on again operates.
You don't understand. The engine control unit is most likely defective. Power transistors burn out. Check each phase of this block, as I wrote earlier. There should be half the voltage on each phase. If the voltage is different, repair of the control unit or a new unit is required.
Thank you for the replying!! I disassemble the engine motor and reassemble in other forklift and operates properly but sounds subnormal. No sound from bearing, no error code dislay
Most likely, one of the engine phases is faulty. Measure the voltage between the negative "-" of the battery and the phase on the engine. The voltage should be half the battery voltage.
