It woukd be easy if the staring battery
is complete seperate from the house battery
. This is the scenerio. The ground from my house battery is connected to my starting battery. So can i still take the ground line from the starting battery, and connect it to the neg post to my second(new) battery. Than can i connect the ground from the new Battery to the original house battery, and connect the positives to the original? Sounds confusion, it is. Any help is appreciated.
