Grounding Batteries to Eng. Block
Started this thread regarding Shunts:
How do Shunts work?
A issue I solved there prompted me to research the Battery/Ground relationship. The book; The 12 Volt Bible For Boats, by Miner Brotherton states:
"Ground is considered to be either an infinite "sink" or an infinite "source" for charge. That means if we have an excess of charge, ground will take all we can give it. If we have a deficiency of charge, ground will supply us with all we need
I think I understand the "sink", meaning ground gives excessive charge some where to dissipate. However, I do not understand how ground supplies us with all the charge we need. If my alternator fails (for example), ground ain't going to help me, right?
Can someone explain what Botherton means?
