Knowing the total speaker load (or impedance) that a set of cabinets, or speakers in a single cabinet, represent is critical. An impedance mismatch (when an amplifier is not rated for the total...
Drip coffeemakers tend to have problems with hot water not flowing from the drip tube, keeping brewed coffee warm, and sputtering or leaking. Coffeemakers run with pump valves and a motor. Here is...
Convection ovens work just like regular ovens but have a fan that circulates hot air around the food. Convection ovens require more energy than most other small home appliances. Here is how to fix...
Corn poppers commonly have problems like scorching or not popping corn or having the motors go out over time. Read on to learn how to fix a corn popper.
A diode is a valve that makes electrical current flow in one direction. You can test if a diode is working with an multimeter. Here's how it's done.
Save yourself time and money by purchasing a volt-ohm meter. Volt-ohm meters are used to find electrical malfunctions in your home. Electricians use them all the time; so why not save yourself the...
An amplifier is an electronic device used to magnify an input signal into a higher output. You can use an amplifier to drive two or more speakers. For this to be successful, the output of the...
Vegetable steamers are handy appliances to have in your kitchen and can save you lots of time preparing healthy dishes for your family. Like other electrical devices, however, their wiring can...
Car amplifiers are not only considered part of the complete car stereo package, but they are also essential in ensuring the appropriate power is distributed to the subwoofer for optimal sound...
If your Whirlpool washer is leaking or not filling properly with water, it's possible the mixing water valve is faulty. There could be cracks on the water valve body, or it might not be closing...
An electric steamer can be used to steam vegetables or cook rice to perfection. The food is healthy since it is not boiled or cooked in oil. Steamers are almost fool proof, but if problems occur,...
The bass rig head is the device that links your bass guitar to your speakers. Choosing one is largely a matter of the technology your speakers and bass require to get the job done.
Learn tips on how to use ohms, including how to match them correctly to your amps, in this free video series that will teach you how to strategically set up your band and musical equipment for a...
Reading and understanding the Ohm rating of a car stereo amplifier is not very easy to understand. Learn tips from our stereo expert on how to control the Ohm loads of your car stereo amplifier...
If you can use an ohm meter, you should be able to determine whether a transformer is good or bad.
Learn the color codes for resistors and the amount of ohms in each resistor in this free video on soldering.
Personally, I know absolutely nothing about changing ANYthing on a Corvete! :) But a little research goes a long way! I found some tips and instructions from some online Corvette experts and...
Calculating Electrical Current Resistance is useful if you have an electrical device that is not working correctly. Especially if that device is constantly tripping the circuit breaker or blowing...
Testing and replacing a refrigerator's compressor relay is not a typical job for the do-it-yourselfer. But, for someone who is willing to try their best to figure out a problem in lieu of...
The Dodge Intrepid is a discontinued model, so you definitely want to keep its parts in good condition. The ignition systems on newer cars can get quite complex, so consult a mechanic or other...
The best way to troubleshoot your Dodge Ram's ignition system depends on the type of system you have. There's plenty you can do on a distributor system, but a distributorless system restricts you...
The Geo/Chevrolet Metro was discontinued at about the time distributorless ignition systems were advancing. So there's a good chance your car could have either type of system. In either case, the...
There are several possible causes of a start-up problem on your old Plymouth Neon. While you shouldn't work on the complex ignition system yourself, you can take steps to detect the problem. The...
Since the Honda Prelude was discontinued around the turn of the century, most of its models have a distributor-based ignition system. Inspecting this system for problems mainly involves testing...
Because the Hyundai Santa Fe is a relatively new vehicle, all versions come with a distributorless ignition system. Such systems are complex and controlled by the Powertrain Control Module, so...
