last week i went over some train tracks and the motor turned on and stayed on. stopped the car and jumped out and pulled the ground. but the motor stayed on. i popped the trunk and looked around and couldnt find what the problem was. the motor was smokin like a sunuvabitch. i didnt have a crescent wrench so i ran to the nearest parts store(a block away) and grabbed one. well the motor had been spinnin for about five min. that night i took it apart put a new seal and motor.the next day it did the same shit! would low batts do that? a homie said that its grounding somewhere but i cant find any thing. any help would be appreciated.
