FAQs about Battery ground wire has current
Does a ground wire carry electricity?
The ground wire will not carry any electricity. But, if the circuit breaker has tripped, the ground wire will remove the current from the system and ground it.

What happens if you put a ground wire between engine and battery?
Let's take a look a the problems this can cause: During cranking, a lot of current flows through the ground strap between the engine and the battery, so there's a voltage drop between the engine and the battery. When you have multiple ground wires that connect between the same 2 points, the current is shared between the two alternate ground paths.
