Tevo Little Monster Power Supply Wiring

  • I have added a Duet Wifi and smart effector to my TLM. Can someone help me to identify which wires from the power supply connector mounted on the control box are for the Power In 12-25V and which are for the heated bed? I thought I labelled them when I removed from the old board but it appers not 😞 I have seen a few pictures but it is hard to tell which is which. Can I tell the difference with a multimeter? Thanks in advance for your help.

  • I have a TLM.... Use a multimeter

    A) with all disconnected wires of bed don't have tension.
    B) Wires from psu have over 25v of tension
    C) for or less in my case, the red wire is the positive
