You might only get one chance at a start with just one. hemisareslow 07-10-2007, 02:19 AM What he said....for the extra cranking amps needed to turn over the high compression of a diesel engine... dennis1 07-10-2007, 02:25 PM Does anyone know if one battery is the primary and the other the secondary? Or are they connected in parallel? Heartbeat Hauler 07-22-2007, 06:28 PM Parallel. | ||
