Battery drains after workshop work: what evidence to ask for

A classic Chevrolet owner's question shows how to distinguish a current draw from a weak battery before paying for parts.

A low-voltage code can be a clue to a broader supply or charging problem, especially when several modules complain at once.

Loose or corroded connections can interrupt power and create symptoms across several systems.

A single electrical component and a whole-car voltage problem call for different first checks.
