    The shunt has to be on the aux battery neg terminal, it’s the only way the BMV 602 will work.

    I have made a new correct wiring diagram that I will post tomorrow when I get access to a scanner.

    Agree, and no devices (-) should be connected directly to the aux (-) besides the shunt. All devices (-) connections should be connected to the “other side” of the shunt.

    It's working!!!

    Thank you so much for the help guys.

    I can confirm that the smartpass is working and does indeed increase charge current.

    Without smartpass = 20A
    With smartpass = +- 40A (saw 60 for a split second but slowly falls)

    Thanks again
