    I found my amp spot in the Pololu Utility program, and rised it from 12 to 20 ampere, that changed my simracing for good. It bacame so responsive = Strong and quick as in 1:1.

    So happy simlife until..

    One motor dies during driving. I suppose that the jrk12v12 board was loaded by to high ampere ? But no smoke or smell or other funktion problem, it's just that it's not working well under load and on one specific axel side.. so one side of axel rotation is strong as before but the other side is falling down when I'm in seat and it getts under load.

    How can i check if a board is messed up ? so it's just some security funktion that it's done to safe it selfe from getting broken, or is it broken alreday ?

    And last question.. If I do want to drive about 20-25 amps of load to get that quick 1:1 motors, how to do ? another pololu driver that is stronger ? or how ?

    Can I use my old one by fixing them, run a diagnostic on them ?

    Thanks for taking time and redaing this..
