In this video we are going to repair 4X4 monster truck toy. There were two problems in monster truck. Firstly its battery pack was bad and secondly it was not moving left and right. We have made the battery pack from the mobile battery BL5C. Right - left movement was not happening due to faulty motor driver IC which we fixed by replacing it with L293D motor driver IC.
