We can check the fuse visually to see if it's broken or we can do an electrical test on the fuse using a multimeter to see if it's good or blown. Visual Test of a Fuse The first test is to do a visual check of the fuse. If the fuse has a broken or melted connector, it is...
Here are some key points to remember: Applications of Continuity Testing: A digital multimeter’s Continuity Test mode is versatile, suitable for testing switches, fuses, electrical connections, conductors, and other components. For example, a good fuse should show continuity. Audible Indicator: The...
Before showing you on how to test or check a fuse, first you need to understand the purpose of a fuse. The function of fuses is to stop higher than normal current to flow to an electronic circuit-it is designed to protect equipment and save electronic components from being damaged and als...
And you can use your multimeter to test virtually any battery ranging from AAAs to car batteries. Note that the above-mentioned technique only tests voltage, not the battery’s ability to supply current under load. The test gives you a rough idea of whether the battery is good, shot, or ...
A digital multimeter (DMM) is one of the most useful test instruments in any automotive electrician's tool kit. Every DMM is slightly different but there are some general guidelines you can follow for its use. An old analog voltmeter will work too but be careful of polarity when using one...
