A test set that includes a circuit breaker, at least two test points, a single pole switch, a double pole switch, and a set of test lights. The at least two test points are for reading amperage when testing a bleed air shutoff valve in aircraft. The at least two test points electronically communicate with the circuit breaker. The single pole switch electronically communicates with the circuit breaker and the at least two test points. The double pole switch is able to open and close and shut off the bleed air shutoff valve electronically. The double pole switch electronically communicates with the single pole switch and the at least two test points. One of the lights is able to inform whether power is being applied to the test set, another light is able to inform whether the double pole switch is open.
