Yes, a test light can be used to determine if a car battery is experiencing an excessive current draw. If the test light illuminates when connected between the negative battery cable and the negative battery terminal, it indicates that there is a parasitic battery drain.
To properly use a test light to check for electrical issues in a vehicle’s battery system, you need to follow these steps: Turn off all electrical components in the vehicle. Disconnect the negative battery cable. Connect the test light between the negative battery cable and the negative battery terminal. Observe the test light.
Lest Jump In! Before you begin testing it is good practice to make sure the test light works. This is easily done by connecting the test light lead to the negative side of the battery and then touching the point of the probe to the positive side battery terminal, the test light should light up.
An acceptable level of battery draw when testing with a test light is less than 50 milliamps. If the draw is more than 50 milliamps, there is likely a parasitic draw. How can you identify the most common causes of battery drain through a test light procedure?
When it comes to testing for a draw on a car battery, a test light is one of the most useful tools you can have. This simple device can help you diagnose a wide range of electrical problems, from a faulty alternator to a parasitic draw caused by a dome light or other electrical component.
A test light is a simple tool that can help you determine if there is a draw on your car battery.
