The light doesn't work and we want to check the bulb but can't figure out how


Look at the bulb filament! If broken it is blown, should be attached at both ends. Also an electrical circuit tester can test for a continuous circuit, if not continuous then blown bulb!

Light doesn,t come on when door opens


Hi there, this sounds like either the bulb or the switch. However your "new bulb @switch" seems to imply that you have already checked them. Can you try to get a multi tester onto the bulb mount to check if there's any current going to the bulb because if it's not the bulb or switch then it has to be the circuit somewhere. I'm sorry but I don't think I have any more suggestions apart from 'put up with no light'. Sorry I can't help any more.

No power to left rear turn/ brake light


Check the display. Ask a helper to step on the brake pedal while you check the lights from the rear. If no lights appear, check the fuse that connects the brake lights. The owners manual will show the location of the fuse box and which fuse is for the brake lights. Pull out the fuse and look at the wire in the central window. If the wire is broken, replace the fuse. Make sure the new fuse is not blown, and carries the same amperage.
Take note of lights that are out, if any are working. The problem may be cured by replacing the bulb in a brake light that's out. A burned out bulb has a broken filament and a dark brown spot on one side. Check the owners manual for bulb type.
Check the circuit if replacement bulbs and fuses do not restore the lights. Find the wiring diagram in the vehicle assembly manual. The circuit for the brake lights runs from the battery to the fuse, to the pedal switch, to a connection plug, to the lights. The circuit has to be checked with a volt tester at all points.
Check the battery power and the light on your volt tester. Turn the ignition key far enough to activate the electrical systems. Turn on the lights to check for battery power. If the battery has power, ues it to check the volt tester. Put the black lead (the ground) from the volt tester on the negative battery terminal. Briefly touch the red tester light on the positive terminal. The light on the volt tester should flash brightly.
Test the wiring to the fuse. Clip the ground wire to solid metal near the fuse. Touch the light tip to both sides of the fuse. Both should light the tester. If neither side lights, the wire between the battery and fuse is bad. If only one side lights, the fuse is blown.
Test the switch and wiring. Touch the light tip of the tester to both terminals on the brake pedal switch without putting any pressure on the pedal. One should carry power and the other should not. When both show power, the switch is stuck and the brake lights are always on. If neither shows power, the wiring between the fuse and the switch is bad. Now check both switch terminals while the pedal is depressed. Both sides should light the tester. If not, the switch is bad.
Check the connection plug. Unplug the connection and refer to the vehicle manual to identify the brake light wire. Touch the tester light on the brake light wire at the inner socket on the battery side. If the tester lights, the power is flowing to this point. If not, the wire between the plug and the pedal switch is bad.
Check the socket. Plug in the connector plug and remove the bulb. Touch the contact inside the socket. If the tester lights, the socket is good. The socket and wire running to the plug should be replaced if the tester doesn't light.
Check the bulb with the ground wire. The bulb must be in its socket. The ground wire running to the socket should be black or brown. Stab the tester through the insulation. If the tester lights, the bulb is good. Replace the bulb if it doesn't light.
Check the ground wire. Remove some of the insulation around the ground wire. Twist one end of the extra wire around the exposed ground wire. Touch the other end to a solid piece of metal. If the brake light comes on, the ground wire is bad.

Replaced dryer drum bulb but light won't come on


First, test the bulb you just installed to make sure it works. Assuming it is a 110-120v bulb, you should be able to do this with any standard lamp in the house. If it's good, next test the socket in the dryer to make sure it has electricity going to it. Do this with a multi-tester and please be careful -- this is a live circuit. Set the tester to its highest AC Voltage setting. Touch the center "button" of the socket and with the other tester probe, touch the outer screw-in shell. It should show 110 to 120 volts. If no power, you'll need to break into the back and make sure all wires going to the socket are connected . . . which may have become jostled.

What one is the live wire for the radio for


Its usually a red or black. You can buy an inexpensive tester to find a live circuit or make your own. Get and 12V bulb and 2 lengths of 16 or 18 gauge wire. Solder one wire to the center contact of the bulb, the other to the metal case of the bulb. Cover the case and exposed solder joints etc with electrical tape. Turn on the radio. Attach the case (ground wire) from the bulb to any metal in the car, use the other (positive end attached to the bulb) as a probe. Probe each plug going into the radio, when the bulb lights, you found a hot circuit.

2001 Chrylser LHS. The battery is being drained when sitting overnight. Will not start in the morning! New Interstate battery has been tested and is good. Any ideas will be helpfull!!!!


TO FIND OUT IF THERE IS A BATTERY DRAIN. TURN OFF ALL SWITCHES, MAKE SURE THE GLOVE COMPARTMENT IS CLOSING RIGHT & THE LITTLE LITE IS GOING OUT. OPEN THE HOOD. IF THERE IS AN UNDER HOOD LIGHT, REMOVE THE BULB, OR UNPLUG THE LIGHT.
CLOSE ALL DOORS TIGHT. WAIT 30 SECONDS AFTER CLOSING THE DOORS, LOOK THROUGH THE WINDOWS, ARE THE COURTESY LITES ALL GOING OUT ." THEY MAY BE ON A DELAY TIMER ". DISCONNECT THE NEGATIVE CABLE FROM THE BATTERY, PUT ONE END OF A 12 VOLT CIRCUIT TESTER ON THE NEG. TERMINAL OF THE BATTERY, PUT THE OTHER END ON A GOOD GROUND. IF THE CIRCUIT TESTER LIGHT COMES ON SOMETHING IS DRAINING. TO FIND THE CIRCUIT THAT IS DRAINING, YOU WILL NEED TO OPEN THE FUSE/RELAY BOX PROBABLY NEAR THE BATTERY. ONE AT A TIME PULL EACH FUSE OUT, UNTIL THE CIRCUIT TESTER LIGHT GOES OUT. WHEN IT GOES OUT READ OWNERS MANUAL TO FIND OUT WHAT IS IN THAT CIRCUIT.

Rear break ligths not working, fuse is fine


check if bulb is busted if not check pedal brake switch, sometimes socket connectors were detached or loose or use light tester to check manually from the fuse connection down to the wiring circuit until you reach the tail of your car. let somebody do the brake pedal pushing when checking using the light tester. i don't see any reason if your problem is not solve using these technique

2002 Isuzu axiom cluster lights and tail lights out


Don't try a higher fuse , it just makes things worse by adding extra burn to the problem.. First make a test lamp with a 21w bulb ( indicator size) .You now have a bulb with two wires attached , insert the "test bulb" across where the fuse should be.
When you switch on the circuit concerned it will glow BRIGHT as it is getting a POS (+) and a NEG (-) ie blowing the fuse (short circuit) in the fuse box and therefore a BRIGHT bulb.
As you disconnect and eliminate or disturb the problem the bulb will immediately glow DULL ( in series contact now) and no longer a short circuit . As you check the circuits the illumination will change and, your on the money ! Let's know how you get on , Good luck

Rear lights


Check the lighting fuses, if these are ok you have an open circuit somewhere. You will need to check it out using some kind of circuit tester to find the fault.
