    Miller AEAD 200LE regulator spade ID

    I have an AEAD that isn't charging the 12 battery. I have reason to suspect that the previous owner did not wire the regulator correctly when he replaced it. Can someone help me identify the two AC terminals on Cummins part number 13950-03-A / 191-2208?

    The reason I suspect it is not wired correctly is that the stator wires pass the ohmmeter test(resistance, not grounded). But the motor runs when connected to the 12 volt battery, and doesn't when the battery is disconnected. I know I shouldn't do that test again unless I want to repair circuit boards. The running and welding with the machine slowly discharges the battery.

    SN - JB520799

    Thanks,
    Carl

    Looks like I have it figured out. I wired it AC|B+|AC. Seems to be charging now.

    You obviously figured it out correctly.

    However, FYI, those regulators "turn off" if the battery is disconnected which is why the engine wouldn't stay running with the battery out of the picture.
