    Hello Neil,
    Thanks for writing in.
    Are you talking about the above item #090482?
    It can’t stop charging automatically. The above circuit diagram is to prevent battery from feed back and damaged item.
    In generall, PWM terminals doesn’t need to be hooked it up. It is connected with microcontroller to control output and adjust current.
    Best regards.

    Hi Aric neeld,
    Thanks for writing in.
    Is it this item? https://www.amazon.com/dp/B01M5CWR2P
    The jumpers is not related to display. When measure 10-120V voltage, the board doesn’t need external power supply, please put jumper at “2W” position.
    For 0-10V measuring voltage, it needs 12-30V external power supply and please put jumper at “3W” position.
    Have you tried to power the display separately？mobile power bank or DC power supply(10-30V)
    Best regards.
