Thats NOT a good sign. First set your truck on somethin to hold the wheels off the ground, so it cant move, then unplug your motor from the ESC, should be 2 bullet cons. Take a AA battery an hook the battery to the motor, if it turns you got other porblems <doubt it> If it dont turn your motor is fried. If thats the case its the perfect time to upgrade!!   Give me a holler had the same problem you do now and got some really good ideas from these guys I'd be glad to pass along in the morning!
