Well I am deployed to middle east.... Truck is at home with wife dead.... We have two vehicles........
2009 GMC Sierra 1500 4-DR C/C, V8, 5.3L, RWD
Just before I left, I installed x2 Red Top Optima Batteries, PAC Brand Dual-B Isolator. Now truck= No Power! WTH?
In order for the Isolator to allow two batteries to be running, the (Signal/Remote) wire (to the PAC Brand Dual Battery Isolator) has to be supplied 12v. Therefore only the (Start) Battery should be enabled, so its not till you start truck, that (Signal/Remote) wire would get 12v, therefore allowing the Alternator to access both Batteries simultaneously (topping off both batteries) If the vehicle wasn't running, the (Auxiliary Battery) should have not being activated via the PAC Brand Dual- Battery Isolator.
So the Batteries should not have killed themselves trying to battle with each other over lower cell voltage.....
I wonder which Alternator was on my truck, maybe rollin' for the six weeks before I left; keeping two batteries charged was too much for a 3.5 year old truck.......?
I heard rumor of two alternators used, one lower amp output, and one higher amp output.....
What are you all's thoughts?
