    Help diagnosing motor problem

    Still getting used to my newly acquired used summit. I took the MMM (still need to change firmware version on esc) and put the Titan 775 and VXL-2 back in and ran it for about 20 min today doing a lot of crawling around the yard. After stopping for a few minutes the motor stopped responding. I charged the batteries and reset transmitter and re calibrated the esc and still no motor response. The light is green on the esc and all servos work as they should. The only thing i did differently today was take the servo horn off the rear diff to manually move rear diff locker into place to diagnose another problem. I put the servo horn back on in the same spot, but it does seem to be struggling a little.

    Both motor and esc setups came with the used package

    Does it sound like the motor is dead? I am not used to working with brushed motors.

    thanks for yet another question.

    I assume you mean EVX2 and not VXL-2?

    Try connecting power directly to the motor.
    If it doesn't spin, the motor is shot.
    Whatever it is I just said... I could be wrong.

    Yes I meant evx-2. Can I use a jump starter for that? If not what is a good source to connect to the motor? Thanks

    Motor runs when powered by separate battery source. Not sure where to go from here. Any thoughts?

    ESC may be malfunctioning.
    That is the only thing feeding it juice from your batteries.

    Does it have any peculiar smell to it?

    No smell. I ordered a new lvp esc from eBay a few days ago. May have to wait till that one comes in.

    New lvp version came in. It works fine now. Not sure what happened to the original one.
