Abstract
A battery charger assembly for charging a battery includes a battery charger power supply having a positive output and a negative output for providing a rectified DC voltage output. A negative cable is connected to the negative output and a positive cable is connected to the positive output with clamps being connected to each of the cables. A polarity indicator including a test contact, a first indicator for indicating a first polarity connection and a second indicator for indicating a second opposite polarity connection is electrically connected to one of the cables. The first and second indicators are connected for indicating if the battery charger voltage output is greater than the voltage of the battery. An electrical connection is provided between the positive and negative cables for actuating the indicators.
