Using a cable tracker can I test 110 volt circuits?

Using a cable tracker I bought from Harbor Freight seems to work with 110 wiring when the circuit breaker is turned off, but can it work safely with the CB turned on. If not, could a capacitor be inserted between the tone generator and the hot wire for isolation? I am trying to find a break in the wire that leaves several receptacles cold while the rest of the circuit is hot. The cable tracker seems to follow the wire all the way to the cold receptacles as being continuous, but voltage measured is zero.

SOURCE: can cat5e cable be wire wrapped?

I tried the same thing once, the diameter and the twist make it useful only in desparate times when you just can't find any mylar wire to use. Been there, done that, now you have the T-shirt. I do use the wire for patching and repair but again it is just much larger than patch wire and not nearly as flexible.

SOURCE: i have a 5000 watt generator with a 20amp

Check and test your voltage output first. It could be your output voltage is 110V, 220V, GND, Chassis(equipment) ground. In reference to Ground point.

Or its output is 110V, 110V, GND, and chassis gnd. Where you have to connect the two 110V output to have 220V output. Then taking 110V - GND to have the 110V.

Check your service voltage for your equipment. So you can wire your system according to your equipment needs.

And green wire should connect to equipment ground.

If your rooms is small in area a two 20A breaker should covered it. And the other one could be SPARE circuit. But still it depends on your needs.

And the last when you got the 25 volts. That might be you only got the neutral point(leak voltage) if I remember it right. Or you have only 1 test point that is live and its connection is loosely attached. Or check your breaker contact.

Hope this helps.

SOURCE: When we measure from hot to neutral we get between 40 & 50 Volts

this is "phantom voltage." To be sure of this you can try shorting the hot with the ground. Should not short. The voltage isn't dangerous. It often happens when two hot wires are in the same cable. For example a 12/3 romex with a shared neutral. When one hot wire is turned off and the other is still energized, voltage can leak from one wire to the other, causing a reading of 50 or so volts on the non powered wire.

SOURCE: House wiring

From your description of the problem, I think the problem is in the white wire (neutral wire). There is a loose connection some where in the line.First, turn off main breaker, then check receptacle for a loose white wire. If none found or this receptacle is the first one in line, then the problem is in the breaker box.Fine where the line enters the box and trace the white wire to where it connects to the neutral buss. Tighten it or repair as necessary

SOURCE: Why does voltage at circuit breaker read 120V and less than one volt at dishwasher junction box?

Say, do you want to play with this?
Could you disconnect the wires at the dishwasher junction box, (remembering exactly where they go) and find an extension cord you could plug in somewhere else to get electricity to the junction box that way? Obviously, you should need to have bare wires to hook to the junction box, so you might be sacrificing an old extension cord, or you might be using romex wire, or something like separate wires. Just be sure you know what you are doing so you don't get ZAPPED. God bless your efforts.

How do you check the alternator

Get a $5.00 tester in Harbor freight and tools
Scale in DC lower scale but grader than 12 volts
tester have a positive red and negative black cable
black to chassis and red on the thick cable of the alternator
should read greater that 13 volts, if less or equal 12, alternator is bad.
-Or remove and take it to a auto part for test

1996 lerado grand cheroke jeep, battery gauge went to to negative, no power new won;t stay running new battery, alternator checks out good any ideas

First check your battery get a cheap digital volt meter. Free at Harbor freight with a purchase. Fully charged battery 12.6 volts Not 12.5 or 4 or 3. With the volt meter set on DC volts touch the battery and have someone start the car if the meter shows high 13.5 to 14.7 the alternator is ok if it is less replace. If you have a dead short take out every fuse and relay from the black box under hood by the battery. Remember where they go and plug them one at a time until the discharge hits and at least you will know what circuit it is.They also sell about 20 dollars a plastic meter you hold over the positive battery cable to see if the starter is drawing to much power A battery open-circuit voltage test will show the approximate state-of-charge of a battery. This test can be used if no other battery tester is available.

Before proceeding with this test, completely charge the battery. Refer to Standard Procedures for the proper battery charging procedures.
  1. Before measuring the open-circuit voltage, the surface charge must be removed from the battery. Turn on the headlamps for fifteen seconds , then allow up to five minutes for the battery voltage to stabilize.
  2. Disconnect and isolate both battery cables, negative cable first.

118345962 Testing Open Circuit Voltage

  1. Using a voltmeter connected to the battery posts (see the instructions provided by the manufacturer of the voltmeter), measure the open-circuit voltage.

See the Open-Circuit Voltage Table. This voltage reading will indicate the battery state-of-charge, but will not reveal its cranking capacity. If a battery has an open-circuit voltage reading of 12.4 volts or greater , it may be tested to reveal its cranking capacity. Refer to Standard Procedures for the proper Micro 420 battery test procedures.

Wire keeps jambing in hose

Make sure you are using a high quality brand of wire. Don't use the junk Harbor Freight sells. Use Hobart or Lincoln Electric. Also make sure your wire feed setting isn't too fast.

Hi I have an electric stick welder ,made by welding industries type mc85 output93amps at 24 volts.Great little machine but it recently got dropped and now doesnt do the frizzzzt thing .The fan works and...

small inverter will not put out the amperage required for welding. if you still have power at the stick and no buzz but a steady melt the rectifier probably crapped out. for light welding harbor freight has a mig thats $90 and will do light jobs decently.

Kinda depends on what you are looking for!
At Harbor Freight you can buy a Volt/ohm/ammeter for about 3 bucks.
Do it.
Use the Amp Meter set for 10 amps. Connect it between the neg. cable and the battery - terminal.
Repeat the fuse pull exercise. The removed fuse that reduces the reading the most is the fuse to the circuit that has your problem (except the hood light and the interior lights - which will be on during this exercise).

Once you have isolated the circuit you should easily find the bad device - or bad wire feeding that device.

Keep us posted on your progress.

My Kenmore 80 series dryer is no longer heating up. The dryer it self is running, we have been able to air dry the clothes, but no heat

If all controls seem to work normally, except that no heat is produced (and is an all electric unit--not gas), then likely the heating element is burnt out (has a break in the wire that heats up and glows, like in your toaster--though the heating wire can sometimes be within a covering metal like your electric range burner, and the break not visable). This is a commonly replaced part; it can be tested for continuity (no break in the wire) with a VOM (Volt Ohm Meter--$2 w coupon at harbor freight this week I noticed) where you set to ohm-resistance (to arrow with + sign if shown and will beep when probes are touching to show a complete circuit) (number would be the same as probes touching, but since resistance wire [to make the heat], there will be some number but not close to that of leads just held not touching anything) or the piece of wire, flashlight bulb, and flashlight battery test (casing of bulb to end of element, battery to end of bulb, piece of wire to other end of battery and on to other end of heating element), where if bulb lights then no break in element (though occasionally wire break can be disconnecting only when large dryer current is applied).
Of course unplugged when do all this testing.
The dryer "working" as it is, is using 110 volts (the controls and the motor) and is separate from the heating circuit which is using both 110 volt sides of the outlet, to equal 220 volts.
Of course, you should check that the connections are solid, and if you have the VOM, you could even use the VOM set to 600v AC to check that the outlet is delivering 110v on both sides of the plug and 220v between the two hot leads (usually black and red, with white the neutral which eventuall connects to ground--if a 4th lead, it is the cabinet ground--usually green or bare).
... and make sure when looking in the cabinet, that there is no build up of lint which can cause the overheating and heating element failure in the first place.

1995 camry running fine up until i parked it for 2 hrs ignition fine timeing belt fine keeps popping 30 amp fuse could that fuse block were the harnesses are plugged to under the dash go bad?

It takes a short circuit to blow a fuse. You could try to disconnet thingsuntil it stops, but that is slow. Better if you buy pulse generator to replace the fuse, then move probe over wire until puse stops at the short in the wire.
Harbor Freight might sell a short circuit test probe and pulse generator.
