I am a little confused about how the dual batteries must be wired. I ASSUMED that if you always had at least one of the batteries connected that all of the circuits would remain powered. I guess that is not true.
I disconnected the main (front) battery to install a jumper cable harness. I left the second battery (side) connected. No problem installing the jumper cable harness.
When I started the truck I noticed the clock had the wrong time displayed and needed to be reset. It apparently lost power while I had the main battery disconnected. All settings in the DIC and all information - odometer, MPG, HRs, trip info, radio pre sets, etc appears to be correct.
Was I wrong to ASSUME that EVERYTHING will remain powered if only one battery is connected and the other one is disconnected??
Arn't both batteries connected to a common harness? They sure appear to be. Anyone else experienced this???
