Lifting automatically after starting up
Checking method:
1. Unplug the coil cable from lifting contactor, then turn on the truck, see if it still lifts automatically.
lf yes, then lifting contactor is faulty, replace it, lf no, check whether lifting button is normal.
2. Use a multimeter to test the continuity of lifting button.
lf the button is damaged, replace it.
If the above causes are ruled out, then lifting circuit has fault.
