How To Check a Blown Fuse

To check a blown fuseThere is a simple step how to check for blown fuse. Set your meter (analog or digital) to ohmsRange or continuity (buzzer test). Point with probes on the top of both edges of the blownmerge. If you are reading a sound or an acoustic signal could hear the shows that the fuse is good. When

there is no sound or even reading the fuse is considered defective and should be replaced.Some glass type fuse will tell you how heavy is the short circuit in the board.A dark fuse blown or cracked show that this was a serious short circuit and only theReplacement of the fuse is usually lead to blow that back. If the fuse has a slight torn(Tungsten) in it are the odds with a new fuse will back up the device operation. Nono matter what, it is still the best to put a series light bulb to prevent the fuse from blowing upagain.About FuseIf you find a fuse that have problems, whether in the main line or in the secondary side ofExample, the pico fuse in the inverter board not only direct you to replace the fuse and turn theEquipment. Chances are high can break the backup. Yes fuses sometimes they have their own lifeRange or is broken when hit by a small wave and by exchanging only the fuse will usually solve theProblem.As for me, I always want to check the fuse for all line along shorted components, especially theSemiconductors, before a new fuse and turn the set "On" again. At the very leastprevent wasting another good backup just in case if it. still problems with the boardAlways scan through all semiconductor devices such as ICs, diodes and transistors.Sometimes a short circuit capacitor (e-cap and non-polar cap) is can also cause, but burn the backupthe percentage is less than compared to a short circuit semiconductor.So do not be happy if you found the fuse open circuit and you still have to solve to findblown out the cause of fuse. If everything to be in order only on the switchEquipment.
