adding a new battery to the house

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.

Re: adding a new battery to the house

All the negative connections go to the same place. There are a few different ways to accomplish this. One is to connect all the negative battery terminals to a stud or buss bar. Another is to daisy chain them.

If you don't understand, get some local help from someone who knows electrical systems.
