The purpose of the work was to investigate the feasibility of a 48- volt cranking system for military diesel engines. Test work was exploratory. The cranking requirements were established for three military diesel engines the Continental AVDS-1790-2, the Detroit Diesel 12V71T, and the Mack ENDT 673. An experimental 48-volt cranking system was tested and compared to the present 24-volt system. The 48-volt system did crank faster and it did produce a quicker start on the Mack ENDT-673 engine. Problems associated with the 48-volt system would be motor and contactor development and design of a dual-voltage circuit to integrate the cranking system with other electrical components.
