If you are working on the construction site of a new building or just remodeling your current house, you will want to use a circuit tester. A circuit tester will check the outlets in the building to see if they are receiving any sort of electrical flow. This is good knowledge to have because you will want to make sure all the outlets are working properly before you send the electricians home. more »
If you are performing home electrical work or are just curious whether a particular circuit is working, you may want to use an analog circuit tester.

To troubleshoot a fuel pump relay, start by pulling the relay out of its socket. Use a circuit tester and check the pins in the socket for power with the ignition key off. There should be one pin that has power direct from the battery. If not, check the fuse and make sure that there is power to the fuse. If not, look for the main wire in the fuse block to be loose or open to the fuse. If the fuse is okay and the relay has power to the one pin, turn the ignition key on. more »
Installing a hanging pendant light outdoors can bring old-world charm to your home, especially when used on a front porch.

How many times have you wondered if your computer or appliance was getting AC power? You can't just look at a line cord or an outlet to determine if it is "hot." You can determine if you are getting AC power by using a non-contact circuit tester. more »
Check the fuses for the blower motor and the relay. Make sure that the fuses are not blown. Check the blower motor and the relay to be sure they have power. Start the car and with the circuit tester check across the fuse for power. Now remove the relay and make sure that there is power to two terminals in the relay's female terminals. With the heater turned on, put the relay back in slowly and listen for it to click, indicating that it was actuated. If it does not click and two terminals have power, replace the relay. Turn off the ignition. more »
When a Honda Civic air-conditioning system (A/C) is being diagnosed, it must have Freon in the system. If the system has sprung a leak somewhere and the Freon is gone, it is no longer an active system that can be checked. A leak would have to be repaired before further diagnosis can continue. Freon can't be released into the atmosphere and must be reclaimed in a machine and reused. There is a major fine for releasing it into the air. For the purpose of this procedure, a circuit tester and a set of air-conditioning gauges will be needed. more »
The blower motor on most vehicles is under the passenger side of the dash, in the area of the glove compartment. The blower motors speeds are controlled by a blower motor resister located in the immediate proximity of the blower motor. It is usually just to the left of the motor. It can be identified by its shape and plug. It is a flat plate about 1 inch by 2 inches. It has a plug with at least five to six wires. This is usually, but not always, the reason for a blower motor failure to operate. The blower motor should be checked first for power before replacing (use a circuit tester). If there is no power, the problem is elsewhere. more »
