[QUOTE="Swsignal5, post: 1171538, member: 18380"] They are tied together In a weird way. The passenger battery is for starting. That is the one that goes directly to the starter and directly to the alternator. The driver side one is the one that powers interior things and I believe the pcm. If you have 1 battery that has the bad and will not start the truck you can put jumper cables in between the driver and passenger side and most of the time get a start. [/QUOTE]
