Question about Gb Electrical Gardner Bender GVD-504A Circuit Alert Non-Contact Voltage Tester

1 Answer

I have 6 outlets that do not work.

I used a Circuit Alert Non-Contact Voltage Tester on them and 3 indicate voltage on both poles of the outlet. The other 3 indicate voltage only on the 'black' or hot pole.

I would start by determining if these 6 outlets are on the same circuit. Also I am usually not too confident in the non contact voltage tester you are using. They tend to give false positives if they contact anything or even if you move them fast. I would invest in an inexpensive multimeter whcih will allow you to test actual voltage across the poles and ground and also check for continuity between poles/ground (WITH CIRCUIT OFF ONLY).

Did these outlets previously work properly?

Does a GB 504 A have a battery?

The 504A uses two silver oxide 357 button batteries. The black top is just press fit in. Gently pry it off. The batteries install with the positive side down.

Voltage tester shows red light on all the 3 cables(including the ground) of a 14-2 home circuit,

HOLD ON!!! The Klein 69127 is an automotive tester to be used for voltages between 6V-24V, AC or DC. The higher voltage in your home could possibly damage the unit as well as yourself. It would be safer for you to use the non contact tester to verify voltage Klien NCVT-1

It only takes a very tiny amount of current to measure voltage. There's always a little tiny current leakage going on, even without contact. Your tester is just telling you the voltage difference between it's own two terminals, even without the other terminal actually touching something, and that difference is 600 volts. Many years ago, my dad showed me a trick using one of those little voltage indicator lights that has little bulb that I think is a neon bulb. If you plug the leads into an outlet, the bulb glows brightly. But if you hold one lead in your hand and stick the other lead into the outlet, the bulb will glow very faintly if the lead is contacting the hot wire. It doesn't glow if you contact the neutral instead. This was very useful to identify hot wires in a box in days before those non-contact voltage detectors that beep.

Irregular function of tester GVD-504A

There are two button cell batteries located in the top of the unit. Try removing the black cap. Some twist off and some pull straight up. Note the polarity of the batteries.

Usage How To

To measure the voltage at an electrical outlet requires the use of a multimeter. Always test your test equipment for proper operation before use. Set the multimeter to AC voltage. The markings may appear as VAC, AC V, or a V beneath a wavy line. Choose the AC voltage closest to the voltage you will measure. Standard current in home and businesses in the USA is in the range of 110 to 120 volts. Some circuits used for equipment such as dryers, air conditioners, electric stoves, ovens and other large equipment may use voltage in the range of 220 to 240 volts. These heavy-duty circuits can be identified by their non-standard outlet plugs. While grasping the insulated portion of the probes (never touch the metal conductor during testing) place one probe into each of the two terminals. The multimeter will display the voltage. Carefully remove the probes, being careful not to touch the metal part of the probes to anything or each other. The voltage should typically test in the range of 108 to 121 volts for most circuits. If voltage is higher or lower, professional electrical service may be required.
