This is a screwdriver-style test probe that is used to test automotive electrical systems (+12 volts or -12 volts only); it allows you to determine the presence of voltage in the area being checked -- I believe its primary purpose is to check for blown fuses.

To use the Screwdriver-Style Automotive Test Probe, take the black wire furnished and plug the end with the metal "rod" on it into the female receptacle (hole) for it on the end of the unit's handle, and clip the alligator clip onto any exposed metal surface of your automobile that you can easily get to.

Start touching various electrical connections with the probe-end of the instrment now; whenever you touch a connection that is "live", a linear incandescent light bulb in the handle will come on.

One handy use for this probe is to check and see if a blown fuse is causing some accessory or other in your auto to not function; you can easily check this by turning your auto's ignition key to the "ACC" position (usually, counterclockwise), turning the "defective" accessory on, and connecting the Screwdriver-Style Automotive Test Probe across the fuse for that accessory. If the probe handle lights up, the fuse is definitely blown, and replacing it *SHOULD* get your recalcitrant accessory functioning again. But if the new fuse blows right away, you have more of a problem than can be fixed with this instrument.

Because the Screwdriver-Style Automotive Test Probe is powered exclusively by your vehicle's battery, I do not have battery changing instructions for you.

The Screwdriver-Style Automotive Test Probe wasn't designed to be used as a flashlight meant to be carried around, thrashed, trashed, and abused; it was also part of an automotive took set that was also a gift from my (now-deceased) best friend. So I won't hit it against the concrete floor of a porch, try to drown it in a toilet, stomp on it, throw it against a wall, throw it at a wall-mounted porcelain urinator to see if it explodes (the test probe, not the urinator), let my mother's big dog's ghost or my sister's kitty cats spring a leak (uranate) on it, hose it down with a gun, run over it with a 450lb Celebrity motorised wheelchair, stomp on it, use a medium ball peen hammer in order to bash it open to check it for candiosity, fire it from the cannoņata, drop it down the top of Mt. Erupto (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piņata Central {aka. "Party Central"}), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoņata (also located at Piņata Central) is only used to shoot piņatas to piņata parties away from picturesque Piņata Island, and Mt. Erupto is an active volcano on Piņata Island), send it to the Daystrom Institute for additional analysis, or perform other indecencies on it that a flashlight might have to have performed on it. So this section of the Screwdriver-Style Automotive Test Probe's web page will be ***SIGNIFICANTLY*** more bare than this section of the web page on a page about a flashlight that was born to be a flashlight and nothing but a flashlight.

Product is part of an automotive tool kit that was given to me by my now-deceased best friend in early-2006.

Because it was not specifically intended to be a light source and because it is a part of a larger automotive tool kit, the conventional "star" rating will not be applied here.
