Can tester SAFELY be used to test ECM signal going to coil and/or injector?

Its current draw is supposed to be about 18mA (green) and 24mA (red), however, the product ships with the following Safety Precautions: 1. For 12V DC systems only. NOT FOR ANY AC VOLT SYSTEM. 2. DO NOT USE THIS TOOL ON COMPUTER CIRCUITRY. 3. DO NOT TEST OR PUNCTURE SPARK PLUG WIRES WITH THIS TOOL. 4. Never use a Test Light to diagnose automotive air bag...

Is this probe safe enough to test 5V automotive reference wiring? Computer safe?

Hello. To be honest I’m not sure if it will pickup a 5v refurance I use it On 12 volt I have a power probe with the 5v connector for it. So I’m not 100 on the test ligh work on that

Does this tester require a connection to the car battery?

Has two alligator clips to connect to a car battery and a power plug so you can plug it into the power source in the dash. Works on any 12 volt circuit. I use it to fix cars and my electric trains.
