A few of the major improvements that needed to be made to the electrical system was that the power supply was too heavy, and that maintenance was going to be difficult if it needed to be done. Also, due to changes in the rules for the 2016 competition a new brake light needed to be purchased.
After some quick calculations, it was determined a simple 9V battery should do the trick, which is a significant weight decrease from a golf cart battery. This year, the car will not be equipped with reverse, making the overall circuit simpler and easier to install. In order to simplify installation and maintenance, more connectors will be used and the new brake light features two holes on the sides for mounting. Last year’s brake light was mounted using a grommet, so if the light needed to be removed, it was easier to take off the entire mounting bracket which was mounted a little too close to the firewall, making it difficult to use any tools. A new mounting bracket is going to be made this year once the brake light comes in and measurements can be taken, and will be mounted in a way that will be more easily accessible. The new brake light also allows for removal while leaving the mounting bracket in place.
