Power cord on DeWalt electric drill

My DeWalt electric drill started tripping a ground-fault interrupter outlet and eventually I traced the problem to the power cord. I removed the cord from the drill and found something I have never seen before on a cord, and neither has the local electric motor shop or the local DeWalt dealer. The three wires from the cord are green, white and black. The black and white wires go to the trigger switch for the drill motor. All three wires also "pigtail" to a common encapsulated or "potted" piece that I am guessing is the problem. The man at the electric motor shop said he'd just cut the potted piece out of the tool. I'm wondering what its purpose is. Any ideas, anyone?

    Rowdy, the drill is a DeWalt DW130V 1/2-inch VSR Drill, Type 1.

    I took the cord to the local DeWalt distributor's service department and the man behind the counter said he'd been working with drills for 30 years and had never seen anything like the potted piece, but guessed it might have something to do with noise suppression.

    So, I came back home and broke the potting compound off and exposed the piece beneath. It was wrapped in fabric tape and under all that were three capacitors, each 0.1 microfarad rated at 250 volts. I think they are miniature electrolytic capacitators. I don't know if they are for reducing sparks at the motor brushes or for reducing radio interference.

    The neutral wire is attached to the (+) lead of one capacitator, with the (-) lead connected to the ground wire; the hot wire is attached to the (-) lead of the second capacitator with the (+) lead connected to the ground wire: the third capacitator is connected across the hot and the neutral wires, with the (+) lead of the capacitor connected to the neutral and the (-) lead connected to the hot wire.

    Thanks for looking into the question, Rowdy. The tool is 115 Volts AC. I unfastened the capacitors and it seems the capacitor from the hot wire to ground may be the problem. (Either that or it isn't!)

    Is this tool a 230V model, that is all I found on their site and most of the parts you have to contact Dewalt for. It sounds like it is for the interferrence also, but you have me stumped on this one, sorry I couldn't help further but if you get any more information let me know and I will try again

Dbx is a family of noise reduction systems developed by the company of the same name. The most common implementations are dbx Type I and dbx Type II for analog tape recording and, less commonly, vinyl LPs. A separate implementation, known as dbx-TV, is part of the MTS system used to provide stereo sound to North American and certain other TV systems. The company – dbx, Inc. – was also involved with Dynamic Noise Reduction (DNR) systems.

My conclusion is that your answer was right on.... good work.

As soon as i plug it in the circuit breaker trips.

You have a short. It is either short to ground or short circuiting. Check the cord very carefully for breaks. Make sure the ground plug is in tacked. Also try a different outlet to make sure the problem is the tool.

I just put together a Sole f63 treadmill (it took forever). I turned the power button on and the display lit up. I pressed the start button and the display shut off. I can't get the display to turn back...

First of all, make SURE that the unit is NOT plugged into a ground fault circuit interrupt (GFCI) outlet. Make sure that the safety key (or safety tether cord's magnet) is on the round metal portion of the console control's head. (It will NOT operate without this in place because it's a safety feature. Also check the circuit breaker under the console, & push it in until it clicks (if it has been tripped (it would extend out if tripped)). Make sure that the power cord is fully inserted in the appropriate power outlet & that the building/home's circuit breaker has not tripped. Otherwise, call your dealer to replace what would be a defective treadmill.

Gfci trips heater not turned on

GFI is Ground Fault Interrupter (or GFCI - Ground Fault Circuit Interrupter) It is doing its job, telling you that there is a short in the unit or wiring. Have a certified electrician check the wiring and unit.

Circut board trips electricty board

Treadmills are machines with a considerable pull of electricity. Make sure you are operating on a dedicated circuit.

Most users have the machine plugged into a spare bedroom outlet ehich is either not dedicate (power source spread out to more then one outlet) or is a GFI outlet (Ground Fault Indicator).

These outlets are used so homeowners do not overload an outlet in an area where a resident will sleep and be in danger of a fore or death.

Usually in the first few pages of your owners manual it will give you the requirements for your machine.

You can run an extension cord to another room with a dedicated outlet, but the extension cord does not transmit all the power coming out of the outlet and will eventually lead to other issues, usually electrical issues within the machine.

You can use a multimeter to see what else could be the issue with your outlet, but will want to consider having an electrician put in a dedicated outlet.

There can be several causes for this symptom. Does the outlet have a breaker or "switch" that is tripped? If this is a GFI (ground fault circuit interrupter) outlet, first disconnect any cord or equipment plugged into the outlet, then press the "reset" button in the middle of the receptacle. The GFI's should not/will not reset with anything plugged in. (If they are working correctly.) More specific information needed if this does not take care of the problem. There are numerous other things which could be causing this problem, loose conections, bad generator, broken or damaged wires on the electrical system, inverter problems, etc. Refer to your owners manual if at all possible, take a look here at this link if you don't have a copy.<<< >>>>

It's possible that you fried it somehow, or you tripped a fuse on the line you are using to power it. Try plugging it into another outlet.

Using a garden auger with the torque set to the highest setting the clutch broke and started to slip. Is this too much for the Dewalt 720 cordless drill? Dewalt is repairing it under warranty.

Yes, luckily Dewalt is taking care of you. You might want to look into a 1/2' drive electric model (sorry with a cord) Alot depends on how hard the ground is but in the long run the big electric will handle about anything you throw at it. Check Sears or Home Depot both good sources for good tools

Switch will not turn on disposal

under the sink you will probably find an electrical outlet with the disposal cord plugged in. If so, plug another item into the outlet like a blow dryer to be sure you have power to the outlet. If you have no power the problem is a tripped breaker or a blown fuse. First check all of the plugs in the kitchen area including under the sink to determine if you have a ground fault circuit interrupter outlet. If you do, it may be tripped. If it is tripped simply reset it.

If you know you have power to the disposal then check to be sure no spoon or other hard object isn't in the disposal preventing it from operating. Use a flash light to check this. If there is no obstruction look on the case of the disposal for a reset button. good luck.
