The requirements for a competition car electrical system are significantly different from those of a standard road car. Such luxuries as electric windows and central locking are superfluous. Conversely, equipment such as emergency electrical cut-outs and fire extinguisher systems may be required. Electrical system reliability is an often-overlooked aspect of competition car design, and a common source of trouble. Here is a practical, illustrated guide to all aspects of electrical system design and implementation, essential reading for anyone running or constructing a competition car or modifying a road car for competition use.
