    Default Coolant pump wired wrong?

    6d2af919-5abe-472b-9705-9762ab5db62f.jpgI have a 1998 Bridgeport Ez Path SD

    When I bought it a few years ago it was wired for 440 at the transformer in the machine. I didnít know it was wired for 440 and wired it of my RPC with 240 three phase to the machine disconnect.It would superheat the dynamic controller. I had a tech come look at It and he found the transformer and reconfigured it for 240 three phase. So the machine runs fine.
    I had only made a handful of parts with it up till now and hadnít used the coolant pump.

    Fast forward to yesterday. I filled the tank and tried to initiate a coolant command and it blows a breaker for the pump.
    Iím thinking the motor is wired for 440 and needs to be reconfigured as there are three different configurations on the plate on the motor.
    My problem is that Iím not savvy enough to understand how to change it by reading the plate.

    Iíll try and post pics for clarity and hopefully help someone steer me in the right direction.6d2af919-5abe-472b-9705-9762ab5db62f.jpg

    The bottom pic in the first post should have been deleted. Can’t figure out how to do that.So it is also in this reply. Anyway, the three pics below are how it’s presently wired. Is this encounter info to get advice from?

    You want the leftmost of the 3 wiring diagrams.

    1 to 6
    2 to 4
    3 to 5

    It looks like your wires are all labeled, so it should be easy.
