How to test a computer transistor driver (without a scan tool)

How to test a computer transistor driver with a basic test light. This test is especially valuable when you have a faulty solenoid and cannot rely on voltage readings when the circuit is energized. Also this is the fastest way to verify wiring integrity of the control wire. A manufacturer flowchart will have you disconnect the computer and solenoid, then measure for opens and shorts with an ohmmeter. It's absolutely ridiculous that this is the standard method of testing a circuit! Suggested test light for this application is an LED type test light. Before performing this test, you must know what polarity to connect the test light to.
