Abstract: A test apparatus for testing an electric starter, a solenoid and a key operated switch of a two or four cylinder engine of an outdoor apparatus. The test apparatus includes a component box for removably supporting the key operated switch, the solenoid and the electric starter. When the key operated starter is closed by turning a key, a light indicator provides a visually perceivable output indication indicating the key operated switch functions to properly close. When the solenoid is connected to the power supply, the solenoid provides an audible output indication indicating the solenoid properly is engaged. When the electric starter is connected to the power supply, the electric starter engages and provides an audible and visual output indication indicating the starter properly is engaged or is properly operating.
