Testing involves using an old fashioned 'test light' with an incandescent light bulb of ten watts or so installed. The clamp end finds a good ground. The pointed end is used to verify battery voltage.
It is useful for verifying that all the signals needed for a relay to work are present...
That a relay, switch or light bulb is getting power... It's ground is indeed making a ground ect.
Volt meters are mostly useless except for learning that yup! 14 volts when it is charging... Ect.
I totally disagree.
I was taught the exact opposite. Test lights are just for quick checks. When it comes to actual diagnostics - DVOMs are king.
Too many times, someone says "I tested it (with a test light)" and the problem is that test lights will light up at 11 volts and higher with very little degree of indication of how low the voltage actually is.
Now, Snap-On makes a test light with a a voltage gauge on it. That is nice
The in tank fuel pump fails when its warmed up. Solved
So, to get home when the car's warm, you have to spray starting fluid into a vacuum line? Also, dude, get a can of PB, some new exhaust studs and nuts, as well as exhaust port gaskets. Fix that exhaust leak. That way, people on FB don't keep going when they see your video on the carthrottle page.

So let's say you want to verify if a washer pump circuit is good....take out the meter? Ok so you measure 12v at the pump wiring between positive and the negative. Is the circuit OK?
Id use a light if I can get the connector loose. But, I'd use my meter with piercing leads if not.
