How can you tell if there's an issue with the DC output connection?

When assessing the health of a DC output connection, the presence of normal charging voltage alongside an absence of amperage is a strong indicator of a problem. This situation suggests that while the voltage is being supplied, the circuit is unable to deliver current to the load or battery. Several factors could contribute to this, such as a break or fault in the connection, an open circuit, or an abnormality within the load itself that prevents it from drawing current even though the voltage is supplied.

In a properly functioning system, both voltage and current should be present when a load is applied. Therefore, if you observe a normal voltage reading but the current (amperage) is zero, this discrepancy reveals that there is likely an issue with the connection or the load, indicating further investigation is necessary.

Other indicators, such as a blinking charger light or the smell of burnt wires, can suggest different problems, but they don't directly define the health of the output connection as clearly as identifying inexplicable voltage without current flow does. A battery draining faster than expected might point to other issues, such as battery wear or excessive load, rather than a direct issue with the output connection itself.
