What is the difference between test light and multimeter?
An incandescent test light is often a better tool for basic troubleshooting as it does pull some current but a multimeter is needed to see if the charging system works, testing continuity without power applied, etc.
Is the old test light bad for your car?
The old style test light can damage auto electronics. Using a test light to check for circuit voltage is a tried-and-true diagnostic method. But if you probe a computerized circuit with your old incandescent test light, you can fry some sensitive and expensive electronics.
What do you need to know about test lights?
Step 1 – A test light is needed to perform electrical power and ground testing to facilitate automotive repairs, this tool is easy to use and is reasonable priced.
What to do if your test light doesn’t light up?
If the light doesn’t light up, check the light by connecting it directly across the battery. Initially, make sure that you have the ground clip on the negative battery terminal. If you touch the probe to the positive terminal, the test light should light up. If it doesn’t and the battery is not completely dead,…
What’s the best way to detect laser damage?
While microscopy is the most common detection method used to identify damage, there are several other detection methods including scattered light diagnostics, plasma spark monitoring, and topography analysis.

Can a Megger test cause damage to a light bulb?
The test current has been known to destroy lights bulbs and printed circuit boards that have been inadvertently left in the electrical system as it is being tested. So instead of testing for damage the megger test can cause damage. The CurrentSAFE Service is a completely nondestructive test in virtually all aspects.
