The polarity L E D test light is a wonderful and safe tool to use on E C M circuits. It has the same construction as a logic analyzer used on chip sets throughout the electronics industry. The reason why the L E D test light is safe, is that it only draws between 20 to 30 milli Amps of current, making it safe for CAM and crank sensors, reference voltages and solenoid circuits. A word of caution, the L E D test light can not be used to test higher current devices. Not because there's any danger in doing so, but because the results are useless. If for example, when using the L E D test light to test an ignition coils or injector ground, it will check out fine and yet the circuit could still have a poor ground. And that's because the L E D will illuminate with only 20 milli Amps. This is a common mistake done in the field, using an L E D test light to test high current components. There are few scenarios worthy of the L E D test light. First scenario, testing a solenoid ..... Get the whole story right here in this video...Enjoy...
