Can you use a continuity tester on Christmas lights?
If you have many strands of lights to test, you can save time by using a divide and conquer approach to testing the individual light bulbs. With this method you test continuity between successively smaller sections of the light strand in an attempt to determine where a bad bulb is located.
What does a Christmas light tester do?
Light testers search for the point in the string where the voltage changes between a good bulb with current flowing and a problem area with minimal current. Christmas light testers typically either detect voltage in a string by displaying indicator lights or through the use of audible beeping sounds.
How does the LightKeeper Pro fix the shunt?
The LightKeeper Pro Quick Fix Trigger sends a shaped, electrical pulse through the defective bulb, clearing the shunt. This allows it to operate properly. The current can then flow through the light set completing the circuit and illuminating the other bulbs.
How can you tell if Christmas lights are bad?
Simply bring the light tester close to each bulb. The tester’s indicator will light up when it’s near a functioning bulb. If you have a non-contact voltage detector, bring the detector close to the wire section between each bulb to test for voltage. The dead section of wire will be the section after your bad bulb.
How does a light keeper work?
Why does half a string of Christmas lights burn out?
1. A light bulb has come out of its socket or is half out of its socket and it has brought down the circuit. For light strings that commonly have over 50 bulbs, they are constructed in 2 or more continuous circuits. If a bulb is missing in a circuit only the bulbs in series of it will go out.
Can I use LightKeeper Pro on LED lights?
No, the LED Keeper uses a different technology specifically developed to perform on LEDs. Fortunately, the LightKeeper Pro is able to fix incandescent holiday lights and has the required technology for these sets.
