Two means of powering trailer ABS systems have been considered in this country. One approach is to provide separate electrical circuits, the other approach is based on the use of the existing 7-pin connector and the stoplamp circuit in it. A number of full-scale vehicle tests were conducted to evaluate the following areas: Electrical power available from tractor stoplamp circuits. ABS power requirements (average and minimum voltage). ABS powering on doubles and triples. In testing double and triple combinations, it was found that improvements in ABS powering for trailers can be made by using full-time power on a separate circuit with increased wire size to the ABS system and by using LED lights. Also found to be critical to powering trailer ABSs were the connectors between the tractor and the trailer and between the trailers.
