During a bus inspection, what is true about battery connections?

During a bus inspection, it is essential to ensure that battery connections are tight and free from any signs of corrosion. Tight connections are crucial because loose connections can lead to poor electrical conductivity, which may result in starting issues or malfunctioning electrical systems on the bus.

Additionally, corrosion can hinder the flow of electricity and may lead to battery failure over time. Regularly checking for tightness and signs of corrosion helps maintain the reliability and safety of the bus's electrical system. These checks are essential regardless of the season and should be performed regularly as part of routine maintenance rather than infrequently or only during specific times of the year.
