AN ANALYSIS AND INVESTIGATION OF TRACTOR AND TRAILER ELECTRICAL SYSTEM CAPABILITIES. FINAL REPORT

The ability of the tractor-trailer electrical systems to satisfy the electrical powering and signalling demands of present and future electrical/electronic systems appears questionable. This study focused on this issue by: Characterizing the ability of a representative sampling of typical new and in-service truck tractors, and one tractor/double trailer combination, to provide electrical power through the stoplamp circuit; Postulating the type and number of electrical/electronic devices that might be installed on trailers in the future; Performing an analysis of the electrical wiring needed to reliably power, through the stoplamp circuit, ABS on multiple trailer combinations; and Suggesting improvement to enable the electrical systems of tractor/trailers to meet present and future electrical power and signalling demands. Recommendations are offered for minimum electrical power output requirements for truck tractors at the tractor/trailer electrical connector.
