What is a potential cause of normal charging voltage yet 0 amperage?

A potential cause of normal charging voltage yet 0 amperage is due to poor circuit connections. When connections are not secure or there is corrosion present, it can prevent current from flowing despite the voltage being present. The voltage indicates that the charger is attempting to supply power, but the poor connection results in a break in the circuit, stopping the flow of current.

This situation can occur in various components of the circuit, such as at the battery terminals or connections where the charger interfaces with the battery. Ensuring proper and clean connections can restore the flow of current and allow the charging process to function correctly.
