Fun Fact November 30, 2021.

Tool time Tuesday and we’re checking for voltage.  I recently bought a 12v test light.  I have a few multi meters that I can use to check voltage, ac and dc, but if I just want to check a circuit on a car I use my new test light, it’s just easier.  Attach the ground clamp to a ground or negative side of the battery and use the probe to check for voltage on whatever you’re checking.  If the light comes on, there is voltage.  If it doesn’t, there is no voltage.  I used it when I installed new head lights in my wife’s Jeep, trying to find a circuit that had power when the key was turned on to the accessory setting so I could wire up the daytime running lights, which the Jeep didn’t originally have.  I remember my dad having a homemade tester.  It was a couple of wires soldered to a 12v bulb, one to the positive, one to the negative.  It worked the same as my fancy store bought one, but didn’t have the clamp on the negative wire, so you had to hold it to the ground.  Listen to the podcast here; https://theriver953.com/lonnies-fun-fact/
