    Question ...

    Are the Brake and the Motor supposed to run at the same time?

    ;constants
    brake Con %00000011
    stmot con %00000000
    runmot con %00000001

    The only way I can see that your symptoms can happen is if the PIC gets reset at the point where it applies the brake.
    Possibly from over current (Brake+Motor).

    The code itself will not do that.

    Good point...I think you are correct. After I wrote my previous post, I was thinking about possibly a brown out condition where it would come up in reset mode. I will check it out and post back.

    Thanks!

    Darrel you are correct!! The brake was hosing the MCU....even though I have 1K resistors...strange I will need to dive more into the hardware.

    Thanks for your help!!!

    Hmmm, must be one of those Canadian brakes (Hoser).
