One of the more frustrating problems to diagnose are complaints of batteries going dead after the vehicle sits overnight. In most cases, the battery is simply old and worn out. But sometimes the battery is not the fault, but instead a component or system is draining the battery when the vehicle has been shut down. In days gone by, a simple test light could be used to identify whether an excessive amperage draw on the battery was present. However, modern vehicles require more sophisticated testing and an understanding of the vehicle network and Power Moding.
