TESTING FUSE

TESTING PROCEDURE FOR FUSE
It is extremely important to understand that if a fuse looks good, it might not in fact be good! Fuses can appear to be fine
and have a break in them so small that it cannot be seen by the naked eye. Therefore, it is important to check a fuse with
an ohmmeter or a continuity tester instead of assuming that it is good.
Use a multi-meter and set the range switch to the lowest resistance range to check the fuse. A good fuse will read 0 ohms
(depending on what the meter reads when the leads are held together), and a bad fuse will read the same as holding the
leads in the air. The illustration below shows how to test a fuse, with the picture's readout showing the fuse as good. There
is no gray area; the fuse is either good or it is not.
