I've got a chevy 7500 dump truck with Cat diesel. It has a pair of batteries. Just started going dead after sitting a few days. First thing I did was to put in a heavy duty battery disconnect, suspecting parasitic drain. That didn't help. I load test the batteries and one checks good, one indicates replacement needed. Do I need to replace both as a pair, or can I get by with just replacing the one that checks bad?
Thanks,
Greg
