    in reply to: Drok Voltmeter / Ammeter not working #19871

    Hello JF，
    We are sorry it is really hard to figure out the wiring from these pictures.
    Did you follow this wiring diagram?
    100043
    According to your description, it seems your power terminal and measuring terminal use the same power. If you follow the above diagram, the meter must be power separately. They can’t share the common ground.
    If it is not that case, we sincerely hope you can draw a simple wiring diagram so that we can check it more carefully. Hope you can understand.
    Best regards.
