|Battery/Motor Connectors (2-pin) from TNC Scooters|

Shortly after I installed the Dorman LED indicator light, it blew out. I quickly diagnosed the problem. The wiring diagram for the controller is as follows:

After changing the connectors and using the go kart a few more times, I noticed problems with overheating of both the motor and controller. The controller seemed to heat up after a few minutes of use and stayed hot. Airflow over the controller from opening the mailbox door did not help. The motor only seemed to heat up when used at low speeds with high load such as driving around in the grass in circles. If you look on YouTube, you will see examples of overheating MY1020 motors:
